What counts as a second home (vs. investment)
Lenders distinguish three property types: primary, second home, and investment. The lines matter because rates, down payments, and qualification rules differ for each.
- Primary residence - where you actually live most of the year. Best rates, lowest down payment, most loan options.
- Second home - a property you use personally for at least part of the year, but not your primary. Slightly higher rates and down payments than primary, but better than investment. Cannot be primarily a rental.
- Investment property - held primarily for rental income or appreciation. Highest rates, highest down payments, often qualifies via DSCR.
Personal use vs. rental
Lenders generally want second homes to be used personally enough to count as recreational/personal property, not income-producing. Renting it out occasionally is fine; running it as a year-round Airbnb is not.
This is where many Florida second-home buyers get crosswise with their lender. They buy a "second home" with the intent to Airbnb it for 30+ weeks a year. That's actually a short-term rental investment property - different loan, different rate, different down payment. Misrepresenting it on the loan application is mortgage fraud. We have the conversation upfront so the loan structure matches the actual use.
Second-home financing details
- Down payment: 10% minimum for most conventional second-home programs. 20% gets the best rates.
- Credit score: 680 minimum, 720+ for the best pricing.
- DTI: Has to handle both your primary mortgage payment and the second-home PITIA. No rental income credit on a true second home.
- Reserves: 2-6 months of PITIA on the second home, in addition to whatever's required for your primary.
- Distance rule: Lenders generally want second homes to be a meaningful distance from your primary - not next door, not in the same neighborhood. The geographic separation supports the "this is a recreational property" claim.
- Rates: Typically somewhat higher than primary residence for the same borrower.
Florida-specific second-home considerations
- No homestead, full property tax. The homestead exemption is for primary residences only. Second-home owners pay full property tax on assessed value with no Save Our Homes 3% cap. As assessed values rise, your tax bill rises with them - significantly different from what your homestead-protected neighbor pays.
- Insurance is harder for absentee owners. If you're at the property less than half the year, some carriers consider it higher-risk (less likely to spot leaks, storm damage early). Premiums are sometimes higher; some carriers won't write second-home policies in coastal counties.
- Hurricane season prep. Owning a Florida home you visit twice a year means you need a plan for hurricane prep: a property manager, neighbor, or service that boards up windows and removes outdoor items before storms. Insurers increasingly ask about this.
- HOA approvals. Some Florida HOAs have buyer-approval processes that work differently for non-residents. Application fees, interview requirements, sometimes longer approval timelines.
- Florida second-home buyers are often retirees or part-time residents. If you're age 65+, asset-based qualification programs are common since W-2 income is gone.
Common scenarios
- Snowbird condo in Naples or Sarasota. Used Nov-April, vacant or family-occupied other months. Standard second-home financing. Insurance and HOA are the variable costs.
- Beach house used by extended family. Owner uses it 8 weeks/year; siblings and kids use it the rest. Still qualifies as second home for lending if the owner controls and uses it.
- "Future retirement home" bought early. Buy now, rent occasionally, transition to primary in 5-10 years. Financing as second home; switching to primary later requires a refinance or just continued ownership.
- Beach condo with occasional rental. Owner uses 6 weeks/year, rents 10-15 weeks via Airbnb when not in use. Most second-home programs allow some rental but want it to remain primarily personal use. Beyond a threshold, it crosses into investment territory.
FAQ
Can I rent my second home occasionally?
Yes - most second-home loans allow some rental, especially short-term/personal-network rental. The line is fuzzy. As a general rule, if rental income is more than incidental and you're targeting STR investment economics, you should be on an investment loan, not a second-home loan. We work through the details upfront.
Does Florida tax me on second-home rental income?
Florida has no state income tax, so no. Federal tax still applies, plus Florida's tourist development tax (a per-county tax on short-term rentals). Some counties also require business tax receipts for STRs. Talk to a CPA familiar with Florida STR rules before going down this path.
Can I deduct mortgage interest on my second home?
Ask your CPA - deductibility depends on your situation.
What if I want to convert my second home into my primary later?
When you change primary residence, you simply start treating the property as your primary - establish residency, file homestead, etc. Your existing second-home mortgage doesn't need to be refinanced for this, though you may want to refinance into a primary-residence loan for the rate improvement.
How does a foreign buyer's second-home loan compare?
A US citizen's second-home loan typically prices a bit above primary. A foreign national loan typically prices higher. The qualification process is also more involved. More on foreign national →
