Can I Use Home Equity to Buy Another House? Your Complete 2026 Guide

Yes. The equity you've built in your current home can be used as a down payment on a second property — whether that's a rental, vacation home, or investment property. Four primary methods do this: a HELOC (bridge loan), a home equity loan, a cash-out refinance, or a home equity investment. Each has different costs, qualification requirements, and cash flow implications. This guide walks through all four, calculates the real math for a common scenario ($500K home, $100K equity, buying a $350K investment property), and shows you exactly how the numbers work — so you can pick the method that fits your situation.

Why Homeowners Use Equity to Buy Investment Properties

Using home equity to fund a second property is one of the most common wealth-building strategies in real estate. The logic is straightforward: you've accumulated equity in your primary residence through mortgage paydown and appreciation. Rather than selling that equity (by selling the home), you borrow against it — converting it into a down payment on a second property without disrupting your current living situation.

For many homeowners, the appeal is financial. Rental properties generate ongoing income that ideally covers the mortgage, taxes, insurance, and maintenance — while the property itself appreciates over time. With a traditional 20% down payment on a $350,000 property running $70,000, pulling that equity from an existing asset is more practical than saving cash from scratch. For a broader look at how these strategies fit into your overall financial picture, see our HEI vs HELOC comparison guide.

The Four Methods: An Overview

Here's how the four approaches compare at a high level before we dive into details:

Method 1: HELOC as Bridge Financing for a Second Property

A home equity line of credit (HELOC) is the most popular method for funding a second property down payment. It works as a bridge: you open a line of credit against your primary residence's equity, draw the funds at closing for your second property's down payment, and repay the HELOC over time — ideally from rental income or your regular cash flow.

HELOCs typically offer variable rates tied to the prime rate, with current rates running roughly 8.5–10.5%. The draw period (when you can access funds) is usually 5–10 years, followed by a 10–20 year repayment period. During the draw period, most HELOCs require interest-only payments, which keeps monthly costs low initially — but the full balance still comes due when the draw period ends.

Qualification requirements for a HELOC used for investment property:

• Credit score: 680–720+ is typical for competitive rates; some lenders go lower with higher rates
• Income documentation: W-2s, pay stubs, tax returns (2 years) — lenders verify debt-to-income ratio including both mortgages
• Equity requirement: You typically need 15–20% equity remaining in your primary home after the HELOC (80–85% max CLTV)
• Ownership seasoning: 6–12 months of on-time mortgage payments; some lenders require 12 months
• Combined loan-to-value (CLTV): Both your primary mortgage and HELOC together can't exceed 85% of your home's value

The investment property itself also needs to qualify. Lenders typically want rental income to cover 125% of the new mortgage payment (the "DSCR" or debt service coverage ratio requirement). This means your lender will want to see that the rental income — not just your W-2 income — can handle the payment with a 25% cushion.

Method 2: Home Equity Loan for a Second Property Down Payment

A home equity loan (sometimes called a second mortgage) works similarly to a HELOC but delivers the funds as a single lump sum rather than a drawable line. The key difference: home equity loans have a fixed interest rate and fixed monthly payment, making budgeting simpler.

For second property purchases, a home equity loan works best when you know the exact amount you need — typically the down payment plus closing costs. If you're buying a $350,000 investment property and need exactly $70,000 for a 20% down payment plus $7,000 for closing costs, a $77,000 home equity loan at a fixed rate gives you predictable payments for the life of the loan.

Current home equity loan rates run roughly 8.5–10.5% fixed on a 10–15 year term. On $77,000 over 15 years at 9%, you're looking at roughly $780/month. That payment needs to be absorbed into your total debt picture — both your primary mortgage and the home equity loan — as lenders will calculate your combined debt-to-income ratio.

Method 3: Cash-Out Refinance for Investment Property Purchase

A cash-out refinance replaces your existing mortgage with a larger one and returns the equity difference to you in cash. If you owe $300,000 on a home worth $500,000, you have $200,000 in equity. A cash-out refi at 80% CLTV would allow you to borrow up to $400,000, pay off the existing $300,000 mortgage, and receive $100,000 in cash.

The advantage of a cash-out refi for investment property: you get a single, clean loan on your primary residence (replacing two separate products with one). The disadvantage: you restart your mortgage clock — you're starting fresh on a 30-year amortization at whatever rate is available today. If you locked in a 3.5% rate in 2020, a cash-out refi at 7.5% on your entire first mortgage is a significant cost.

Current 30-year cash-out refinance rates run roughly 7.5–8.5%. The total cost includes closing costs of $3,000–$8,000 (appraisal, title, origination) plus the ongoing rate difference on your entire mortgage balance. For a detailed comparison of this approach against a home equity loan, see our cash-out refi vs home equity loan guide.

Method 4: Home Equity Investment for Second Property Purchase

A home equity investment (HEI) from companies like Hometap works differently from the other three options — and for certain borrowers, that's precisely the advantage.

With an HEI, you receive a lump sum of cash in exchange for giving an investment company a percentage of your home's future value. There are no monthly payments for up to 10 years and no income verification required. The cost comes at settlement (when you sell, refinance, or reach year 10): the investment company receives their agreed percentage of the home's value at that time.

For investors using equity to fund a second property, HEI can be the cleanest option for one key reason: your cash flow from the rental property doesn't need to cover two mortgage payments (one on the primary residence and one on the HELOC or home equity loan). The HEI has no monthly payment. This dramatically changes the DSCR math on your investment property — you're not required to show rental income that covers both debts.

The tradeoff: if your primary home appreciates significantly over 10 years, you're sharing that appreciation growth with the investment company. In a flat or declining market, the HEI cost is minimal. In a strongly appreciating market, you're giving up a larger share of your home's equity gains. For a full analysis of HEI costs and how they compare to traditional loan products, see our guide on what home equity investments really cost.

Down Payment Strategy: Using Equity to Meet the 20% Threshold

Investment property mortgages typically require 20–25% down payment (conventional loans). On a $350,000 property, that's $70,000–$87,500 in cash — a significant amount for most people to have sitting in savings. Your home equity provides the bridge.

The standard approach: pull the down payment from your primary residence's equity via HELOC or home equity loan, close on the investment property, then either sell the primary home (eliminating the HELOC balance) or keep it as a rental too. Many investors use this "house hacking" strategy: live in one, rent the other, build from there.

Key considerations for the down payment strategy:

• LTV requirements on the investment property: Most lenders want 20–25% down to avoid PMI on investment properties. Some allow 15% with a higher rate.
• HELOC draw timing: Some HELOCs need to be drawn before the investment property closes — your lender will want to see the down payment funds "seasoned" (in your account for a period of time). Plan for a 30–60 day gap.
• Cash reserves: Most lenders require 6–12 months of reserves (mortgage payments) in the bank after closing — even on the investment property. Don't drain your savings for the down payment without leaving this cushion.
• Two-property tax implications: You can deduct interest on both mortgages if properly structured. Work with a tax advisor to understand how holding a second property affects your filing position.

Cash Flow Analysis: Rental Income vs. Monthly Obligations

This is where the four methods diverge sharply. Let's use a concrete scenario to show the cash flow difference: you have a $500,000 home with $100,000 equity (20%), and you're buying a $350,000 investment property with a 20% down payment ($70,000).

The investment property: $350,000 purchase price, 20% down ($70,000), $280,000 mortgage at 7.5% over 30 years = roughly $1,958/month principal + interest. Add property taxes ($3,500/year = $292/month), insurance ($1,500/year = $125/month), and maintenance reserve ($350/month) = total monthly cost of roughly $2,725.

Reasonable rental income in most mid-market areas for a $350,000 property: $2,200–$2,800/month. At $2,500/month rental income, you have a monthly cash flow gap of roughly $225 before accounting for the equity-access method costs. Here's how each method affects that gap:

• HELOC ($70,000 at 9% variable, 10-year term): Adds ~$880/month in HELOC payments (interest + principal). Total monthly gap: ~$1,105/month — you need to cover this from W-2 income or it erodes the investment thesis.
• Home equity loan ($70,000 at 9% fixed, 15-year): ~$710/month. Total gap: ~$935/month from your regular income.
• Cash-out refi (full restart at 7.5%): Depends on your existing rate. If you had a 4% mortgage, you're paying 3.5% more on $300K+ — roughly $875–$1,000 more per month on your primary residence mortgage alone, plus the new investment property costs. This scenario typically only works if you had a high first-mortgage rate already.
• Home equity investment ($70,000 received, no monthly payment): $0 per month on the equity access. Your only monthly obligations are the investment property itself (~$2,725/month). With $2,500 rental income, the gap is ~$225/month — a fraction of what HELOC or home equity loan scenarios create. Hometap can show you how much equity you could access with no monthly payment, changing the investment property cash flow math entirely.

Tax Implications: What You Can and Can't Deduct

Investment properties have specific tax advantages that affect which equity-access method makes the most sense after-tax:

Mortgage Interest Deduction

Interest on up to $750,000 of acquisition debt (the original mortgage to buy the property) is deductible on investment properties. This includes the mortgage on the investment property — not the HELOC or home equity loan on your primary residence. The interest on your primary residence's HELOC or home equity loan is generally deductible only if the funds were used to buy, build, or substantially improve your primary home (not to purchase a different property). This is a critical distinction: if you take a HELOC on your primary home and use the proceeds to buy an investment property, the interest on that HELOC may not be deductible.

Workaround: If you cash-out refinance your primary home and use those funds for the investment property, the interest may be deductible under the "acquisition debt" rules — but only for the portion used to acquire the investment property. Consult a tax advisor to structure this correctly.

Rental Income Reporting

Rental income is taxable at ordinary income rates — not capital gains rates. However, you can deduct operating expenses: property management fees, repairs, insurance, property taxes, depreciation (using IRS Form 4562), and mortgage interest on the investment property loan. The net rental income (or loss) flows through to your personal tax return and can offset other income — particularly valuable if you have W-2 income in a high tax bracket.

Capital Gains on the Investment Property

When you sell the investment property, capital gains are taxed at 0/15/20% (long-term) or your ordinary income rate (short-term, held less than one year). Your primary residence has the $250,000/$500,000 exclusion — investment properties do not. If you're using a home equity investment on your primary residence and selling it at term end, the settlement proceeds may fall within the primary residence capital gains exclusion. The HEI on your primary residence is not a loan, so there's no mortgage interest to deduct — but the appreciation sharing structure is different from a loan's interest cost. For a full breakdown, see our guide on HEI tax implications.

Risk Analysis: What If Both Properties Have Mortgage Payments and Values Drop?

Owning two mortgaged properties creates real risk that deserves honest analysis. Here's the scenario that keeps investment property owners up at night: home values drop, rental income falls (vacancy or rent cuts), and you're covering two mortgages plus maintenance from your W-2 income.

On our $350,000 investment property scenario with a $280,000 mortgage at 7.5% over 30 years: the property needs to sell for roughly $315,000+ (closing costs + remaining mortgage) to avoid a loss. In a 20–25% market correction, a $350,000 property could fall to $262,500–$280,000 — potentially underwater or barely above water. The HELOC or home equity loan on your primary residence compounds this: if your primary home also drops in value, your combined LTV rises and you may have difficulty refinancing or accessing additional equity.

Risk mitigation strategies:

• Maintain 12+ months of reserves: Both investment property and primary residence (with HELOC balance) should be covered by liquid savings for at least 12 months of payments. This is the single most important risk buffer.
• HEI as a risk buffer: Unlike a HELOC with monthly payments, an HEI has no monthly payment obligation. If rental income drops to zero (full vacancy), your only cost is maintaining the property — not a HELOC payment on top of the investment property mortgage. This flexibility is genuinely valuable in a downturn.
• Cash-out refi in a high-rate environment: If you have an existing first mortgage below 5.5%, avoid cash-out refi in the current rate environment. The rate penalty on your entire first mortgage is likely worse than the benefit from the equity access.
• DSCR underwriting buffer: Lenders requiring 125% DSCR (rental income covers 125% of mortgage) already builds in a 25% vacancy/price correction buffer. Don't stretch beyond this buffer — the margin exists for exactly this scenario.

State-Specific Considerations: Community Property States and Foreclosure Risk

If you live in a community property state (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin), your spouse automatically owns half of everything acquired during marriage — including home equity. Both spouses typically need to sign HELOC and home equity loan documents. If you're considering using home equity for an investment property and your spouse is not on the title, factor in the additional documentation and consent requirements.

On foreclosure risk: using home equity products to fund an investment property creates two secured debts against your primary residence. If you default on the HELOC or home equity loan while carrying an investment property mortgage with cash flow pressure, the lender on your primary residence can foreclose — potentially forcing the sale of your home to satisfy the debt. The investment property, meanwhile, would still have its own mortgage and could also face foreclosure. This is an extreme scenario, but it's why cash reserves and the HEI's no-payment structure are worth careful consideration for risk-averse investors.

HEI vs. HELOC for Investment Property: A Direct Comparison

The critical question for investment property buyers: HELOC or HEI? Here's how they differ across the dimensions that matter most:

For investment property buyers with strong W-2 income, a HELOC may be the lower-cost option over a 10-year horizon. For buyers with variable income, those relying on the rental cash flow to cover both mortgages, or those with a tight cash flow margin — the HEI's zero monthly payment can be the difference between a profitable investment property and a money-losing one. Hometap offers estimates with no credit impact so you can compare both options before deciding.

Real Math: $500K Home, $100K Equity, $350K Investment Property — All Four Methods

Let's make this concrete. You have a $500,000 primary residence, $400,000 remaining on your mortgage, and $100,000 in equity. You're buying a $350,000 investment property with a 20% down payment ($70,000). Here's how all four methods play out:

Method 1: HELOC ($70,000 at 9% variable)

You open a $70,000 HELOC on your primary residence. Draw period: 10 years (interest-only at ~$525/month), followed by 20-year repayment at ~$700/month average over the life of the loan.

Investment property: $280,000 mortgage at 7.5%, 30-year = ~$1,958/month. Total monthly housing obligations: ~$2,458–$2,683/month (HELOC + investment mortgage). Rental income: ~$2,500/month. Monthly cash flow: roughly $0 to $42/month (before taxes, insurance, maintenance reserves). W-2 income must cover vacancy, repairs, and any payment gaps.

10-year total HELOC cost (interest paid): ~$31,500 in interest over 10 years (rough estimate at 9% on declining balance).

Method 2: Home Equity Loan ($70,000 at 9% fixed, 15-year)

Fixed monthly payment of ~$710/month. Investment property mortgage: ~$1,958/month. Total: ~$2,668/month. With $2,500 rental income, monthly gap: ~$168/month from your regular income. Predictable and stable, but the gap exists.

10-year total home equity loan cost: ~$22,000 in interest over the first 10 years of the 15-year term.

Method 3: Cash-Out Refinance

Only works if your existing first mortgage is above ~5.5%. Refinancing a $400,000 mortgage at 3.5% to $500,000 at 7.5% costs you ~$1,167/month more on the primary residence alone. Combined with the investment property ($1,958/month), your total monthly cost could exceed $3,125/month before HELOC-equivalent costs. This scenario typically only makes sense if your first mortgage is above 6.5% and the investment property cash flow is strong enough to absorb the combined debt.

Method 4: Home Equity Investment ($70,000 from Hometap)

You receive $70,000 upfront with no monthly payments for 10 years. Investment property costs: $1,958/month (mortgage) + taxes + insurance + maintenance = ~$2,725/month total. Rental income: $2,500/month. Monthly gap from income: ~$225/month — significantly lower than the $880–$935/month gap created by HELOC or home equity loan.

HEI cost at year 10: If home appreciates at 4% annually, your $500,000 primary residence is worth ~$740,000 in 10 years. On a $70,000 investment with a 10–15% equity share, the settlement cost is ~$74,000–$111,000. Compare this to ~$31,500–$40,000 in HELOC interest paid over 10 years. In strong appreciation markets, HEI costs more. In flat or modest markets, HEI can be the cheaper option — and the zero monthly payment is worth the premium for investors with tight cash flow margins.

Which Method Is Right for Your Second Property Purchase?

Here's a decision framework based on your financial situation:

1. Do you have a low first-mortgage rate (below 5.5%)? If yes, avoid cash-out refi. The rate penalty almost certainly outweighs any benefit.
2. Is your W-2 income strong enough to absorb a $700–$900/month additional payment? If yes, a HELOC or home equity loan is likely the lower-cost option over 10 years. Fixed-rate home equity loan preferred if you want payment predictability.
3. Is your cash flow tight or income variable? If yes, HEI eliminates the monthly payment and dramatically improves the investment property's cash flow. The equity share cost is the premium you pay for that flexibility.
4. Do you need funds quickly (within 4–6 weeks)? HEI providers like Hometap can often move faster than HELOC/home equity loan underwriting, especially if you have equity but documentation is complex.
5. Are you in a community property state? Factor in both spouses' consent requirements and jointly-held debt implications into your planning.

For most investment property buyers with stable W-2 income and strong credit, a home equity loan (fixed rate, predictable payment) is the cleanest path: manageable cost, clear obligation, deductible interest if properly structured.

For buyers who can't comfortably absorb an additional $700–$880/month, who have income variability, or who want the rental property cash flow to be self-sufficient — HEI from a provider like Hometap transforms the math. No monthly payment means the investment property needs to generate far less rental income to break even.

Common Questions

Can I use a HELOC to buy a second house?

Yes. A HELOC on your primary residence is one of the most common ways to fund a second property down payment. You draw on the line of credit at closing on the investment property, then repay the HELOC over time. Most lenders allow this, though they may require proof the funds were used for the purchase (closing disclosure, etc.). The key requirements: 680+ credit score, documented income, 6–12 months of on-time mortgage payments on your primary residence, and enough equity (typically 15–20% remaining after the HELOC to stay below 80–85% combined LTV). The HELOC interest may not be deductible unless the funds are used to buy, build, or improve your primary residence — consult a tax advisor.

Does a home equity investment affect my ability to get a mortgage on the second property?

Not directly — an HEI is not a loan, so it doesn't appear as a debt obligation on your credit report the way a HELOC or home equity loan does. However, lenders may note the HEI lien on your primary residence during the mortgage underwriting process, and some investment property lenders have specific overlays about subordinate debt on the subject property. Most borrowers with an active HEI on their primary residence have successfully obtained investment property mortgages, but discuss it with your mortgage broker early in the process.

What credit score do I need to use home equity for an investment property?

For traditional products (HELOC, home equity loan, cash-out refi): 680–720+ for competitive rates, 700+ for cash-out refi. For home equity investments: soft credit check only with minimum scores of 500 (Unlock, Point) to 550 (Hometap). If your credit score is below 680 and you can't qualify for a traditional product, an HEI is a realistic path to accessing your equity for a second property — without the income verification and credit score requirements that would otherwise block you.

How much down payment do I need for an investment property with home equity funds?

Most conventional lenders require 20–25% down on investment properties (versus 3–5% on primary residences). On a $350,000 property, that's $70,000–$87,500. Some lenders allow 15% down with a higher interest rate, though private mortgage insurance (PMI) applies. Using home equity funds from your primary residence is the standard way to meet this threshold without saving cash from scratch. Additionally, most lenders require 6–12 months of mortgage reserves (cash in the bank) even after the down payment — don't drain your savings to fund the down payment without maintaining this reserve.

Is it risky to use home equity for an investment property?

It carries real risks that deserve honest assessment. The primary risk: you now have mortgage obligations on two properties. If rental income falls short (vacancy, rent reductions in a softening market) or your personal income is disrupted, you're covering both mortgages from reduced cash flow. Secondary risks: HELOC rates are variable and can rise 2–4% over a 10-year draw period; home values can decline, reducing your equity cushion on both properties; and the HELOC interest deduction has strict rules limiting deductibility for investment property purchases. The risk is manageable when: you maintain 12+ months of reserves for both properties, your W-2 income comfortably covers both mortgages if rental income hits zero, and your investment property is in a market with strong rental demand. For cash-flow-sensitive investors, an HEI's zero monthly payment reduces the monthly risk exposure significantly.
