The Quick Version
A vacation home costs more to finance than the house you live in, and one line item explains most of it: a one-time Fannie Mae fee, 1.125% to 4.125% of the loan, set by how much you put down. Ten percent is the floor. Twenty percent clears mortgage insurance. The distance between those two numbers runs into five figures on a Blue Ridge cabin. Below, the rate premium, the deposit, and PMI, costed against Fannin County’s July 2026 median.
Why do second home mortgage rates run higher than on your primary?
Because the loan carries a built-in fee your everyday home does not. When Fannie Mae buys a vacation-home mortgage, it bills the lender a loan-level price adjustment. The lender hands that cost to you, either as a higher rate or a charge at closing.
I’m Thomas Echea. After seventeen years advising buyers in Blue Ridge and Fort Lauderdale, I can tell you this single item surprises more second-home buyers than anything else on the sheet. It is not a penalty on the property. It is priced off one figure: how much you borrow against the value.
How much is the second home rate premium, exactly?
It runs from 1.125% to 4.125% of the loan, and your deposit decides where you land. Fannie Mae’s Loan-Level Price Adjustment Matrix, version 01.28.2026, sets the second-home fee on loan-to-value alone. Your credit score is priced elsewhere, on a separate grid. Put more cash down and the charge steps lower, as of 2026:
| Down payment | Loan-to-value | Second-home fee |
|---|---|---|
| 10% (the floor) | 90% | 4.125% |
| 15% | 85% | 4.125% |
| 20% | 80% | 3.375% |
| 25% | 75% | 2.125% |
| 30% | 70% | 1.625% |
| 40% or more | 60% or lower | 1.125% |
The cliff sits between 15% and 20% down. Cross it and the fee drops from 4.125% to 3.375%, three-quarters of a point bought back with the final slice of your deposit.
How much do you need to put down on a second home in the North Georgia mountains?
Ten percent is the floor on a conventional vacation-home loan. Fannie Mae limits a one-unit second home to 90% financing on a purchase, so you cannot go lower. Across the North Georgia mountains, a Blue Ridge cabin near the county median needs roughly seventy thousand dollars in cash before closing costs.
There is no zero-down conventional route on a getaway home. The government programs built for small deposits, FHA and VA, cover a primary residence only. Whether your income and debt load clear the bar is a separate test, one I walk through in qualifying for a second home.
When does PMI apply on a second home, and how do you avoid it?
Private mortgage insurance begins the instant you borrow more than 80% of the value, so any purchase with less than a fifth down carries it. PMI sits on top of principal, interest, taxes, and the fee already folded into your rate.
On a $630,000 balance at an assumed 0.5% annual premium, that is about $3,150 a year, near $263 a month, until you reach 20% equity. A full fifth down erases it outright. Later, insurers drop it as the balance shrinks and the home gains value.
What does the down payment and surcharge actually cost on a Blue Ridge cabin?
More than most buyers pencil in, which is why I run the figures before anyone tours. Fannin County’s median list price was $699,950 in July 2026, at a median $325 per square foot. Take a round $700,000 cabin and watch the fee move with the deposit:
| Down payment | Cash down | Loan amount | Fee | Fee cost | PMI |
|---|---|---|---|---|---|
| 10% | $70,000 | $630,000 | 4.125% | $25,988 | Yes |
| 20% | $140,000 | $560,000 | 3.375% | $18,900 | No |
| 25% | $175,000 | $525,000 | 2.125% | $11,156 | No |
| 40% | $280,000 | $420,000 | 1.125% | $4,725 | No |
The step from 10% to 20% down trims the fee by about $7,100 and kills the monthly PMI. That is a five-figure swing before the first payment, decided entirely by the size of the check you carry to closing.
What about closing costs?
Set aside another 2% to 5% of the loan beyond the deposit. These pay for the appraisal, title work, lender fees, and prepaid taxes and insurance. On a $560,000 loan, that is roughly $11,000 to $28,000 due at the table.
A refinance carries its own version, paid by the borrower. That is why refinancing to shed PMI only pays once the rate or the equity clears the bill. For how the whole structure fits together, see how second-home financing really works.
Second home financing: common questions
Can a person hold two home mortgages at one time?
Yes. Lenders routinely approve a mortgage on a vacation home while your primary loan is still open. What they underwrite is whether your income covers both payments within their debt-to-income limits, plus cash reserves, not the number of mortgages itself.
Are mortgage rates higher on condos?
Often, yes. Fannie Mae adds a 0.75% loan-level surcharge on a condo above 75% loan-to-value, on top of any second-home charge, which lenders convert into a slightly higher rate. Below 75% loan-to-value the condo surcharge falls to 0.125%.
How does private mortgage insurance affect homeowners?
PMI raises your monthly payment without building equity, since it protects the lender, not you. It applies while you owe more than 80% of the value and falls away once you cross that line, either by paying down the balance or through appreciation.
Can a larger down payment eliminate mortgage insurance?
Yes. Put 20% or more down, keeping your loan at or below 80% of the value, and no PMI applies. On a second home that same move also drops the Fannie Mae surcharge from 4.125% to 3.375% of the loan.
Who pays closing costs when refinancing a home?
The borrower does. Refinance closing costs run about 2% to 5% of the new loan and are paid by the homeowner, though many lenders let you roll them into the balance rather than bring cash.
How can you buy a second home with little or no down payment?
Not through a standard second-home loan, which floors at 10% down. Buyers who put little cash in usually pull it from elsewhere, most often a cash-out refinance or a home-equity line on their primary residence, then buy the second home with those funds.
Why are mortgage rates higher on a second home, and by how much?
Because of the Fannie Mae second-home surcharge, which runs 1.125% to 4.125% of the loan by loan-to-value. Lenders fold that one-time charge into the rate, so a second-home rate typically sits a fraction of a point above a comparable primary-residence loan.
