Can I Get a Second Mortgage to Buy Another House?

A second mortgage, such as a home equity loan or HELOC, allows you to borrow against your primary home’s equity to buy of another home, whether for investment (e.g., rental or fix-and-flip) or personal use (e.g., vacation home). This 2nd-mortgage program offers lower interest rates than unsecured loans and potential tax benefits, but it carries significant risks, including foreclosure.

In 2025, with U.S. median home prices at approximately $412,000, homeowners are increasingly leveraging their home equity to expand real estate portfolios or secure second homes.  This article explores how to use a second mortgage to buy another house, investment property or vacation home. We will evaluate the eligibility requirements, benefits, and risks in taking out a second mortgage to buy another house.

Can You Use a Second Mortgage to Buy Second Home or Vacation House?

Yes, you can use a second mortgage to buy another house, either as an investment property or a second home.

The 2nd-mortgage funds can cover a down payment (10–20% for second homes, 15–25% for investment properties) or, with substantial equity, the entire purchase price.

For instance, a $100,000 HELOC could fund a 20% down payment on a $500,000 rental property or fully purchase a $100,000 fixer-upper.

Lenders typically allow borrowing up to 80–85% of your home’s value, minus the first mortgage balance, provided you meet these requirements:

• Equity: At least 15–20% equity after borrowing (e.g., $80,000 on a $400,000 home).

• Credit Score: Minimum 620–680, with 740+ securing lower rates. (Non QM lenders offer bad credit 2nd mortgages and private lenders offer hard money second mortgages as well.)

• DTI Ratio: Below 43–50%, including both mortgages and other debts like car loans.

• Income Stability: Verified through pay stubs, tax returns, or rental income projections for investment properties.

• Appraisal: To confirm your home’s value and combined loan-to-value (CLTV) ratio (80–85% max). Some lenders offer a no appraisal HELOC option.

For investment properties, lenders like Griffin Funding may consider the new property’s rental income to offset DTI, requiring a Debt Service Coverage Ratio (DSCR) of 1.0–1.25. Second homes, often vacation properties, require stronger personal income due to no rental offset. Closing costs (2–5%, or $2,000–$5,000 for a $100,000 loan) and higher rates than primary mortgages (6.88–7.26% APR) are common, per Forbes.

Can I Get a Second Mortgage to Buy an Investment Property?

Yes, you can get a second mortgage, such as a home equity loan or Home Equity Line of Credit (HELOC), to buy an investment property by leveraging the equity in your primary home. Equity is your home’s market value minus the mortgage balance (e.g., $200,000 equity on a $400,000 home with a $200,000 mortgage). In 2025, with median home prices at $412,000, many homeowners have substantial equity to fund purchases like rental properties or fix-and-flips. Lenders require 15–20% equity post-loan, a 620–680+ credit score, and a debt-to-income (DTI) ratio below 43–50%, including both mortgages.

For example, a $100,000 HELOC at 7.95% APR from U.S. Bank could cover a 20% down payment on a $500,000 rental property, with interest-only payments of $663 monthly during the 10-year draw period. Benefits include lower rates (7–9% APR) than personal loans (12.65%) and potential tax-deductible interest for investment property expenses, per IRS rules.

However, risks are significant: defaulting risks foreclosure of your primary home, and higher rates than primary mortgages (6.88% APR) plus closing costs (2–5%, or $2,000–$5,000) increase costs. Lenders like Griffin Funding may offset DTI with rental income projections (DSCR ≥1.0). Compare offers from multiple home equity lenders ensuring the property’s rental income ($2,500/month for a $1,800 mortgage) supports repayment. Use a mortgage calculator to estimate borrowing capacity and consult a financial advisor to mitigate risks and align with your investment goals.

• Home Equity Loan: A lump sum with a fixed interest rate (e.g., 7.96–8.41% APR in 2025) and term (5–30 years), ideal for one-time purchases like a down payment.

• HELOC: A revolving credit line with variable rates (7.25–10.75% APR), allowing flexible draws during a 10-year draw period, suited for ongoing expenses like property renovations.

Both require your home as collateral, meaning defaulting risks foreclosure. Lenders assess your credit score, debt-to-income (DTI) ratio, and equity to determine eligibility.

Benefits of Using a Second Mortgage to Buy Another Home

Using a second mortgage to buy another house offers several advantages:

• Lower Interest Rates: Second mortgages (7–9% APR) are cheaper than personal loans (12.65%) or credit cards (20.12%), saving significant interest. For example, a $50,000 home equity loan at 7.96% over 15 years costs $335 monthly, versus $595 for a personal loan at 12%. Shop for today’s best 2nd-mortgage rates.

• Flexible Funding: HELOCs allow you to draw funds as needed, ideal for staged purchases or renovations, paying interest only on the amount used (e.g., $167 monthly for $25,000 at 8% APR).

• Wealth Building: Investment properties generate rental income or appreciation (3–5% annually), increasing net worth. Second homes can serve as future rentals or retirement properties.

• Tax Benefits: Interest on second mortgages used for home improvements or investment properties may be tax-deductible, per IRS rules (IRS). Consult a tax advisor for eligibility.

• Quick Access: Funds are available in 5–40 days, faster than some traditional loans, per NerdWallet, suiting competitive real estate markets.

Considerations

Despite the benefits, using a second mortgage carries significant risks:

• Foreclosure Risk: Defaulting on a second mortgage risks losing your primary home, as it’s collateral. Ensure repayment fits your budget.

• Higher Interest Rates: Second mortgages have rates 1–2% higher than primary mortgages, increasing borrowing costs. For example, a $100,000 HELOC at 8% APR costs $667 monthly in interest-only payments.

• 2nd-Mortgage Closing Costs: Fees of 2–5% ($2,000–$5,000 for $100,000) can offset savings, especially for smaller loans.

• Market Volatility: If the new property’s value drops or rental income falters, repayment becomes challenging, especially for investment properties.

• DTI Impact: A second mortgage increases your DTI, potentially limiting future borrowing or affecting primary mortgage refinancing.

To mitigate risks, compare offers from at least three lenders, like Bank of America or PNC Bank, and use calculators from Bankrate to estimate payments and borrowing limits. Maintain a financial cushion (6–12 months’ expenses) and ensure the new property’s income or your budget supports both mortgages. Consulting a financial advisor is crucial to assess long-term impacts and tax benefits.

Case Study 1: Using a HELOC for an Investment Property

Homeowner: Sarah, a 42-year-old accountant in Denver, Colorado.
Background: Sarah owned a $500,000 home with a $250,000 mortgage, leaving $250,000 in equity. With a 720 credit score and $80,000 income, she wanted to buy a $300,000 rental property to generate passive income.
Action: Sarah secured a $100,000 HELOC from U.S. Bank at a variable 7.95% APR with no closing costs. She used $60,000 as a 20% down payment on the rental property, financing the remaining $240,000 at 7% APR. The HELOC’s monthly interest-only payment was $398 for the $60,000 drawn.
Outcome: The rental property generated $2,500 monthly income, covering its $1,800 mortgage and yielding $700 profit. Sarah’s total monthly payments ($2,198) fit her 40% DTI. The property appreciated 3% annually, adding $9,000 to her net worth in one year. The HELOC’s flexibility allowed her to draw additional funds for minor renovations, boosting rental value.

Case Study 2: Using a Home Equity Loan for a Second Home Down Payment

Homeowner: Michael, a 50-year-old engineer in Miami, Florida.
Background: Michael owned a $600,000 home with a $300,000 mortgage, leaving $300,000 in equity. With a 740 credit score and $100,000 income, he wanted to buy a $400,000 vacation home in Orlando.
Action: Michael took a $80,000 home equity loan from Discover at a fixed 7.96% APR over 15 years, with no closing costs, for a 20% down payment ($80,000) on the second home. His monthly payment was $536, and the second home’s mortgage ($320,000 at 6.5%) cost $2,022 monthly.
Outcome: Michael’s total payments ($2,558) fit his 38% DTI. The vacation home served as a family retreat and occasional Airbnb, generating $1,500 monthly when rented, offsetting costs. The fixed-rate loan ensured stable payments, and the home’s value rose to $412,000 in a year, increasing his wealth by $12,000. Michael plans to rent it full-time in retirement.

Simple Steps to Get a Second Mortgage to Buy Another Home

1. Calculate Equity: Subtract your mortgage balance from your home’s appraised value.

2. Check Credit and DTI: Ensure a 620+ credit score and DTI below 43–50%. Improve credit by paying down debts.

3. Research 2nd Mortgage Lenders: Compare at least three lenders, like second mortgage rates, fees, and terms. Check for fixed-rate home equity loans or HELOCs with fixed-rate lock options.

4. Prepare Documentation: Gather pay stubs, tax returns, mortgage statements, and details of the new property (e.g., purchase price, rental projections).

5. Apply and Appraise: Submit applications to multiple lenders within 45 days to minimize credit score impact. Expect an appraisal to confirm home value.

6. Close and Use Funds: Pay closing costs (if applicable) and use funds for the down payment or purchase.

Using a second mortgage to buy another house in 2025 is a viable strategy for leveraging home equity to build wealth or secure a second home. Sarah and Michael’s case studies demonstrate how HELOCs and home equity loans provide flexible, cost-effective funding for investment properties and vacation homes. With rates at 7–9% APR, second mortgages are cheaper than unsecured loans, but foreclosure risks and closing costs require careful planning. By comparing lenders, ensuring repayment affordability, and consulting financial advisors, homeowners can successfully use second mortgages to achieve their real estate goals while safeguarding their primary home.
