The Quick Version
A second home mortgage is a separate pricing category, not a primary loan with a different address. Fannie Mae has charged a second-home loan-level price adjustment since April 1, 2022, running 1.125% to 4.125% of the loan amount and tiered by loan-to-value. You pay it in rate or in cash at closing. As of August 2026, plan on 10% down, a property you control year-round, and the 2026 conforming ceiling of $832,750 before jumbo pricing starts.
Buyers call me about a cabin and quote the rate they saw on a mountain cabin financing site. That number is a primary-residence rate. The financing they actually want is priced somewhere else entirely, and the gap is not a rounding error. I’m Thomas Echea, a Luxury Real Estate Advisor with Compass, and I work the Fannin County and Blue Ridge market every week. Here is how second-home financing really works before anyone writes an offer.
Why is a second home mortgage priced higher than your primary?
Because Fannie Mae surcharges the occupancy category itself. Since April 1, 2022, second-home loans carry a loan-level price adjustment ranging from 1.125% to 4.125% of the loan amount, tiered by loan-to-value. Credit score is priced separately, through the base credit-score and loan-to-value grid, so the two stack.
The adjustment is quoted as a percentage of the loan, not as a rate. Your lender converts it, and you either pay it in cash at closing or absorb it as a higher rate for thirty years. Most buyers absorb it and never see the line item. Here is how the current LLPA matrix tiers it.
| Down payment | Loan-to-value | Second-home LLPA |
|---|---|---|
| 10% | 85.01–90.00% | 4.125% |
| 15% | 80.01–85.00% | 3.375% |
| 20% | 75.01–80.00% | 2.125% |
| 25% | 70.01–75.00% | 1.625% |
| 40% or more | 60.00% or less | 1.125% |
Freddie Mac’s weekly survey put the 30-year fixed average at 6.67% for the week of August 13, 2026. That is the primary-residence benchmark. A second-home file lands above it, and how far above depends almost entirely on how much you put down.
What does a second home actually have to be to qualify?
Fannie Mae’s Selling Guide is specific, and lenders enforce it. The property must be a one-unit dwelling, must be suitable for year-round occupancy, and you must occupy it for some portion of the year. You need exclusive control over it.
Two disqualifiers bite hardest in cabin country. Timeshare arrangements are excluded outright, as is any contract handing a management firm authority over occupancy. A rental agreement dictating who stays and when is precisely what pushes your file into investor pricing.
Year-round suitability trips up mountain buyers most often. A cabin reached by a road the county abandons each winter, or plumbing rated for summer alone, invites an underwriting question better answered during due diligence than under contract.
What the payment looks like on a cabin in the North Georgia mountains
Run the whole number, not the principal and interest. Fannin County’s 2025 millage stack in the unincorporated county is 9.073 mills — 2.440 county plus 6.633 school — and Georgia assesses at 40% of fair market value under O.C.G.A. § 48-5-7. That works out to $362.92 in county property tax per $100,000 of value.
On a $700,000 cabin outside the city limits, that is roughly $2,540 a year. Inside Blue Ridge city limits, the municipal 3.826 mills pushes the stack to 12.899 and the bill up accordingly. I pulled those figures from the county’s five-year levy notice and the Georgia Department of Revenue millage report, not from a listing portal. Our breakdown of Fannin County property taxes walks through exemptions and due dates.
Layer on hazard insurance, dearer up here than statewide averages suggest, plus any road or HOA assessment. Escrow lines wreck cabin budgets far more often than interest rates do.
Can you buy a second home and not live in it?
Leaving it empty is permitted. Renting it through a management agreement is not. Fannie Mae’s guidance treats identified rental income as tolerable rather than fatal, provided that income never supports your qualification and every remaining occupancy condition still holds.
That opening is narrower than it sounds. The moment an outside company governs the calendar, your declared occupancy type is simply wrong. If short-term rental is the plan, price the file as an investment property from the start — our note on second home vs. investment property when you plan to rent covers where that line falls.
How do I apply for a second-home mortgage?
The application resembles a primary one, with two wrinkles. Underwriting qualifies you carrying both housing payments, so your debt-to-income ratio must absorb the existing note, escrow, and hazard premium alongside the new obligation. You also sign an occupancy certification describing your intended use.
Demand the loan estimate showing that surcharge as a dollar figure before comparing lenders. Two quotes advertising an identical rate can hide wildly different settlement costs once the occupancy premium surfaces.
Is second-home mortgage interest still tax-deductible?
Yes, beneath a ceiling most buyers misread. IRC § 163(h) permits deduction on the first $750,000 of acquisition debt for financing originated after December 15, 2017. Anything predating that cutoff may still enjoy the legacy $1 million allowance.
Crucially, that ceiling is aggregate rather than per-dwelling. Your principal residence and one elected companion property divide the same $750,000 allowance. Own several and you nominate which qualifies each tax year. Consult your CPA before folding any deduction into a purchase budget.
Frequently asked questions
Why are mortgage rates different on second homes?
Fannie Mae attaches a loan-level price adjustment of 1.125% to 4.125% to this occupancy category, effective for loans purchased on or after April 1, 2022. Lenders recover it as discount points or bake it into the note rate, which is why your quote sits above whatever the national average says that week.
What is a good second home mortgage rate right now?
Freddie Mac’s Primary Mortgage Market Survey averaged 6.67% on the 30-year fixed for the week of August 13, 2026. Treat that as a floor, not a target. The survey measures owner-occupied lending, so your quote inherits the occupancy surcharge on top of it.
Can you buy a second home and not live in it?
Vacancy is fine. Delegation is not. Occupy the place some portion of each year, retain exclusive authority over who enters it, and you stay inside the guideline. Hand the calendar to a rental company and the file gets repriced as an investment property.
Is second home mortgage interest still tax-deductible?
Within a shared cap. IRC § 163(h) allows interest on $750,000 of acquisition debt for loans originated after December 15, 2017, and that allowance spans your main residence plus one elected second dwelling — combined, never doubled. Older financing may fall under the prior $1 million threshold. Your CPA should confirm before you budget around it.
How much do I need to put down on a second home?
Ten percent opens the door, though the pricing tiers punish thin equity. Contribute 10% and the surcharge lands at 4.125% of the balance; contribute 20% and it falls to 2.125%; contribute 25% and it drops again to 1.625%. Few choices on the application move your cost this sharply.
When does a second home loan become a jumbo loan?
Once the balance clears $832,750, the Federal Housing Finance Agency’s 2026 baseline for a one-unit dwelling, announced November 25, 2025. Fannin carries no high-cost designation, so nothing local lifts that threshold. Borrow above it here and you are shopping jumbo underwriting.
