What credit score do I need to buy a home?

Most conventional loans require 620 minimum. FHA accepts 580 for 3.5% down. The best rates require 740+. Improving your score 20-40 points before applying can save tens of thousands in interest.

How much money do I need to buy a house?

Budget for down payment (3-20%), closing costs (2-5% of loan), and 3-6 months reserves. On a $350,000 home with 5% down: roughly $17,500 down plus $8,000-15,000 closing costs plus $10,000+ reserves.

How long does it take to buy a house?

From starting your search to closing: 3-6 months is typical. Pre-approval takes 1-3 days. Once under contract, closing takes 30-45 days.

Are mortgage rates higher for a second home?

Yes. Second home mortgage rates are typically 0.5% to 0.75% higher than primary residence rates. Investment property rates are even higher — often 0.75% to 1.25% above primary residence rates. Lenders charge more because second homes have higher default risk than primary residences.

Second Home Mortgage Guide: Requirements, Rates, and Tax Implications

Buying a second home — whether a vacation getaway, a place closer to family, or an eventual retirement destination — is a significant financial undertaking with its own distinct mortgage rules, rate premiums, and tax considerations. Understanding the difference between a second home and an investment property is critical, as lenders and the IRS treat them very differently.

Second Home vs. Investment Property: The Critical Distinction

The label "second home" has specific meaning for both lenders and the IRS:

Criterion	Second Home	Investment Property
Occupancy	Owner must occupy personally for part of the year	Primarily rented; owner may rarely or never stay
Down Payment	Minimum 10% (often 20%)	Typically 20–25%
Mortgage Rate	0.5–0.75% above primary residence	0.75–1.25% above primary residence
Rental Income	Can rent occasionally; IRS rules apply	Primary purpose is rental income
PMI	Available	Usually not available; large down required
Loan types available	Conventional; some VA (primary only)	Conventional primarily

Key IRS rule: If you rent your "second home" for more than 14 days per year AND your personal use is less than the greater of 14 days or 10% of the rental days, the IRS may classify it as an investment property — changing the tax treatment significantly. Consult a tax advisor before renting your second home.

Second Home Mortgage Requirements

Down Payment

Most lenders require a minimum of 10% down on a second home. Some conventional programs allow 10% down with strong credit (740+). Many lenders prefer 20% to avoid second home PMI and provide better rate pricing. See our Down Payment guide for strategies to reach your target.

Credit Score

Second home financing typically requires higher credit scores than primary residences:

Minimum: 620–640 for most lenders
Better pricing: 700+
Best pricing: 740+

Debt-to-Income Ratio

Your existing primary mortgage payment, the new second home payment, and all other debts are all included in your DTI calculation. This is why second home financing can be challenging even for financially strong buyers — two mortgage payments dramatically increase monthly debt obligations. See our DTI guide and use our Affordability Calculator to model your DTI with both mortgages included.

Reserves

Lenders typically require 2–12 months of reserves (mortgage payments for both homes) after closing. More than a primary residence because maintaining two properties creates more financial vulnerability.

Occupancy Requirements

The property must be suitable for year-round occupancy and must be a reasonable distance from your primary residence (lenders won't accept a "second home" two blocks from your primary). You must intend to occupy it personally for at least some period each year.

Interest Rates for Second Homes

Second home mortgage rates are typically 0.5–0.75% above primary residence rates. On a $400,000 second home loan, this premium costs approximately $120–$180/month, or $1,440–$2,160 per year. Over 30 years, that rate premium costs approximately $43,000–$65,000 in additional interest.

Tax Implications of Second Homes

Mortgage Interest Deduction

Mortgage interest on a second home is generally deductible for loans up to $750,000 combined (primary + second home) under the Tax Cuts and Jobs Act of 2017. Interest on loans above this threshold may not be fully deductible. Consult a tax advisor for your specific situation.

Property Taxes

Property taxes on a second home are deductible subject to the $10,000 SALT (State and Local Tax) deduction cap, which combines with your state income taxes. In high-tax states, this cap significantly limits the deductibility of second home property taxes.

Rental Income Tax Treatment

The "14-day rule" governs tax treatment when you rent your second home:

Rented 14 days or fewer per year: Rental income is not taxable; property is treated as a personal residence for deduction purposes
Rented more than 14 days AND personal use meets threshold: Mixed use — rental income is taxable; expenses are allocated between personal and rental
Investment property classification: All rental income is taxable; rental expenses are deductible

Financing Strategies for Second Homes

Cash-out refinance on primary: Access equity from your primary home to use as down payment on the second home — possibly at a lower rate than second home financing
HELOC on primary: A home equity line on your primary provides flexible access to down payment funds — see our HELOC guide
1031 exchange: If selling another investment property, a 1031 exchange can defer capital gains taxes on funds used for real estate reinvestment
Vacation rental income projection: Some lenders will consider expected rental income in qualification — typically requiring a history of rental income or market rental documentation

What is the down payment for a second home?

Minimum 10% for most lenders, often 20% preferred. Investment properties require 20–25%. The distinction between second home (personal use) and investment property (primarily rented) determines which requirement applies.

Are rates higher for a second home?

Yes — typically 0.5–0.75% above primary residence rates. Investment properties are even higher at 0.75–1.25% above primary. Use our Mortgage Calculator to model the exact monthly payment.

Can I rent out my second home?

Yes, but with important limits. Renting 14 or fewer days per year keeps the IRS treating it as a personal residence and rental income is tax-free. Renting more than 14 days may change tax treatment. Consult a tax advisor before renting your second home.
