Can You Rent Out Your Second Home?

Yes — but there are strict rules about how much you can rent it out while still qualifying for second home financing (not investment property financing).

→

Personal Use Requirement: You must personally use the property for at least 14 days per year OR 10% of the days it's rented, whichever is greater.

→

Rental Income Counting: For second home loans, rental income generally cannot be used to qualify. For investment property loans, 75% of rental income can count toward your income.

→

Airbnb/VRBO Rules: Short-term rental platforms are allowed, but heavy rental activity (300+ days/year) may cause lenders to reclassify as investment property.

→

Tax Implications: If you rent for 14 days or less per year, rental income is tax-free. If you rent more, you must report income but can deduct expenses proportionally.

How to Qualify for a Second Home Mortgage

1. Pay Down Debt First

With both mortgages counting toward your DTI, you need to be below 45%. If your current DTI is 35%, adding a second mortgage payment may push you over. Pay off car loans, student loans, or credit cards first.

2. Build Cash Reserves

Lenders want 2-6 months of PITI reserves for second homes. On a $2,000/month second home payment, that's $4,000-$12,000 in savings beyond your down payment and closing costs.

3. Improve Your Credit Score

The 680 minimum gets you approved, but 720+ gets significantly better rates. A 40-point improvement from 680 to 720 can save 0.25% on your rate — $16,000 over 30 years on a $350K loan.

4. Document the Property as Second Home

The property must be suitable for year-round occupancy, not a timeshare or rental-only property. It should be in a vacation/resort area or at least 50 miles from your primary residence (some lenders require this).

Frequently Asked Questions

What is the minimum down payment for a second home?

The minimum down payment for a second home (vacation home) is 10% with conventional financing. FHA and VA loans cannot be used for second homes — they are for primary residences only. With 10% down, you'll pay PMI until you reach 20% equity.

What credit score do you need for a second home mortgage?

Most lenders require a minimum 680 credit score for a second home mortgage, though 720+ gets the best rates. Second home loans have stricter requirements than primary residence loans because lenders consider them higher risk.

Can I rent out my second home?

Yes, but with limits. For a property to qualify as a second home (not investment property), you must personally use it for at least 14 days per year OR 10% of the days it's rented, whichever is greater.

What is the difference between a second home and investment property mortgage?

Second home mortgages require 10% down and offer rates 0.25-0.50% above primary residence rates. Investment property mortgages require 15-25% down and have rates 0.50-1.00% above primary rates. The key difference: second homes must be used personally; investment properties are purely for rental income.
