Two hours north of the city, a cabin with a sagging dock and a kitchen last updated in 1978. The buyer already owns a house with a mortgage and has a decent deposit saved. Nothing about the purchase feels unusual. Then the quotes come back half a point higher than what their neighbour got on a near-identical loan.
That gap exists because lenders sort every property into one of three buckets: primary residence, second home, or investment property. Each bucket carries its own down payment rules, rate add-ons and paperwork. Second homes sit awkwardly in the middle. You get better terms than a landlord would, because you intend to use the place yourself, but you pay for the privilege compared with the house you sleep in most nights. Budget for roughly 0.375% to 0.875% on top of primary residence pricing, depending on the lender and loan size.
What a lender means when they say “second home”
The definition is narrower than most buyers expect. A second home is a property you intend to occupy for part of the year, in a location that isn’t your primary residence, and that you don’t rent out as a business. Fannie Mae and Freddie Mac require the property to be a reasonable distance from your main home, and many lenders translate that into a 50-mile rule. Buying a flat three streets from your house and calling it a second home will get the file pushed back.
You’ll sign an occupancy affidavit at closing. Lenders do follow up, and renting the place out 300 days a year while claiming it as a second home is occupancy fraud, not a grey area. If the property is already under a rental management agreement when you close, expect it to be treated as an investment property from day one.
The main second home mortgage types
Conventional second home loans
This is the default and covers most purchases. Because Fannie Mae and Freddie Mac buy these loans, pricing is standardised and widely available. A typical structure: 10% down for a single-unit property, a 620 minimum credit score on paper (most approvals land at 700 or above), debt-to-income up to 45% with compensating factors, and two months of reserves. The conforming loan limit is $806,500 in most of the country for 2025, higher in expensive counties.
One detail catches people out. Put 10% down and you’ll pay mortgage insurance, usually borrower-paid, adding somewhere around 0.3% to 0.6% of the loan annually until you reach 20% equity. On a $400,000 loan that’s real money each month, and it doesn’t come with the same cancellation flexibility as on a primary residence.
Jumbo second home mortgages
Anything above the conforming limit moves into jumbo territory, where lenders set their own rules. Expect 10% to 20% down, a 700 to 740 score, and six to twelve months of reserves covering both properties. Counterintuitively, jumbo pricing for a clean file is often close to conforming pricing, because lenders compete hard for wealthy borrowers. Where it gets expensive is anything unusual: a condo hotel, a home on 40 acres, a property without a working kitchen.
Fixed-rate versus adjustable
Seasonal properties suit adjustable-rate mortgages well. A 7/6 or 10/6 ARM on a lake house you’ll keep for a decade can save meaningful interest compared with a 30-year fixed. If the plan is to hold the property into retirement and hand it to your kids, take the fixed rate and stop thinking about it.
Portfolio and private bank loans
Local banks, credit unions and private banks hold loans on their own balance sheet, which means they can ignore agency rules. This is where you find asset depletion underwriting for retirees without paycheques, bank statement programmes for self-employed buyers, interest-only structures that suit a place used eight weeks a year, and financing for non-warrantable condos that Fannie Mae won’t touch. Relationship pricing is real: move $250,000 in investments to the bank and rates often improve by a quarter point or more.
Borrowing against your primary home instead
Some buyers skip second home pricing altogether and take equity out of their main residence at primary-home rates. That can be cheaper, and it’s faster. The trade-off is that your family home now secures the debt, and there are limits on how much mortgage interest you can deduct across both properties. If this route appeals, read up on how purchase and refinance mortgages differ before you commit, because the cost structure is genuinely different.
What you cannot use for a second home
A surprising number of buyers assume any loan product is available. It isn’t.
- FHA loans. Primary residence only, with an occupancy certification at closing.
- VA loans. The VA guaranty exists to help veterans buy homes they’ll live in. A pure second home doesn’t qualify, and the exceptions for renting out a previous VA-financed home are narrow.
- USDA loans. Primary residences in eligible rural areas, full stop.
- Down payment assistance programmes. Almost universally restricted to primary homes.
- DSCR loans. Priced for rental property. If you plan to rent the place out most of the year, a debt service coverage product is the honest fit, not a second home loan.
The broader split between agency-insured and privately funded loans explains a lot of this. If you want the detail, this breakdown of conventional versus government-backed mortgages shows where the cost difference actually appears, and this list of the seven types of government-backed mortgages makes clear how few of them apply to a holiday property.
Costs that catch second home buyers
Insurance is the big one. A home left empty for months can attract a higher premium, and some carriers want a monitored alarm, a neighbour checking weekly, or a property manager’s visit logged. Standard homeowner policies sometimes exclude long vacancies entirely, so read the wording.
Property tax quietly rises too. Homestead exemptions and resident discounts vanish when the property isn’t your primary home. Florida, for instance, offers no homestead benefit on a second home, and some states charge non-resident transfer taxes on purchase. Add HOA dues, higher utility costs in a seasonal climate, and the fact that a second home often needs a vehicle kept there. None of these show up in a loan estimate.
The rental question, and why it changes everything
Many buyers intend to rent the property “a bit” to offset costs. That single intention can reshape the loan.
On the tax side, the IRS gives you a useful line: rent the home for fewer than 15 days in a year and you don’t report the income at all, though you also can’t deduct rental expenses. Rent it more, and the rules get more involved, including limits on how many days you can personally use the place while still treating it as a residence.
On the lending side, rental income from a second home generally isn’t counted toward qualifying, because the loan is underwritten on the assumption you’ll use it. Once you start renting it consistently, expect to refinance into an investment property loan with different pricing and different reserve requirements. Better to plan for that at the start than to discover it two years in. Understanding what living in a property actually unlocks on a primary residence mortgage helps here, since the perks you give up by buying a second home are exactly those occupancy-based benefits.
Matching the loan to the way you’ll use the place
Be honest about the usage pattern before comparing rates.
Four to six weekends a year, mostly summer. A 10% down conventional loan with an ARM is efficient. You keep capital free and the rate resets are manageable over a short holding period.
Two months a year, with an eye on retiring there in 12 years. Fix the rate. Pay the extra half point. Certainty is worth more than the marginal saving when the horizon is long.
Complicated property or complicated income. Talk to two local banks before any national lender. A condotel, a converted barn, a home on land zoned agricultural, or a business owner taking distributions rather than a salary will all be easier with a portfolio lender who can apply judgement.
Heavy rental plans from day one. Skip the second home category entirely and underwrite it as an investment, with a DSCR or investment property loan. You’ll pay a similar rate and avoid a conversation with your lender later.
Get quotes from at least three lenders, and ask each one two direct questions: what rate add-on applies for second home occupancy, and how many months of reserves they require across both properties. Those two numbers move more than the headline rate. If you’re still narrowing the field, this practical approach to working out which mortgage type fits your situation is a sensible next step before you start collecting loan estimates.
