Everyone shopping a vacation place asks the same question first: how much higher is the rate? It is the wrong question. Fannie Mae does not publish a separate rate sheet for second homes. It charges a one-time fee at delivery, and your lender turns that fee into whatever rate bump it needs to cover.
That matters because fees have breakpoints and rates do not. Move from 20% down to 25% down on a $600,000 place and the fee drops by more than nine thousand dollars. Move from 24% to 25% and you cross the same line. Nobody tells you where the line is.
Below are the current rules, the actual fee schedule, and what the premium costs you in dollars. First, a short walkthrough of how lenders classify these loans.

1What Lenders Count as a Second Home
Quick Answer: A second home is a one-unit property you occupy part of the year, control yourself, and do not run as a rental. Get the classification wrong and the loan is repriced as an investment property, which is a different loan product with a lower borrowing ceiling.
Occupancy is the first thing an underwriter decides, before rate, before down payment. Fannie Mae’s Selling Guide occupancy rules set six tests, and a second home mortgage has to clear all of them.
- You occupy it for some portion of the year. There is no minimum night count in the guide, but a property you never visit is not a second home.
- One unit only. Duplexes and triplexes cannot be financed as second homes at any down payment.
- Suitable for year-round occupancy. A summer cabin with no heat and no winter road access usually fails here.
- You have exclusive control. No rental management firm can decide who stays there or when.
- Not a rental property or timeshare. Occasional rental income is tolerated, but only if it is never used to help you qualify.
- An automated Approve/Eligible finding. Second home files run through Desktop Underwriter rather than manual review.
The rental carve-out is the one people misread. You are allowed to rent the place out sometimes. What you cannot do is count that income on the application. The moment rental income helps you qualify, the file becomes an investment property.
2How Much Down Payment a Second Home Needs
Quick Answer: Ten percent is the floor. Fannie Mae caps second home purchases at 90% loan-to-value, so the second home down payment cannot go below 10% on a conventional loan. Most buyers should target 25%, for reasons that have nothing to do with what they can afford.
The Fannie Mae Eligibility Matrix sets three ceilings for one-unit second homes: 90% on a purchase, 90% on a rate-and-term refinance, and 75% on a cash-out refinance. Those are hard limits, not lender preferences.
FHA, VA and USDA loans are all off the table. Every one of those programs requires the home to be your primary residence, which leaves conventional financing as the only mainstream route to a second home mortgage.
The 10% floor comes with a catch. Below 20% down you also carry private mortgage insurance, on top of the occupancy fee covered in the next section. Two costs stack on the same loan, which is why very few second home buyers actually close at 10% down.

3Second Home Mortgage Rates: Where the Premium Lives
Quick Answer: Second home mortgage rates are not set separately. Fannie Mae charges a one-time occupancy fee of 1.125% to 4.125% of the loan, and your lender converts it into a rate bump or asks for it in cash at closing. The fee is driven entirely by loan-to-value, not by how mortgages normally price.
These charges are called loan-level price adjustments. Every conventional loan gets them, layered by credit score, loan purpose and property type. Second homes carry one extra layer that primary residences do not, and the schedule below is the whole of it.
| Down Payment | Occupancy Fee | Fee | LTV Band |
|---|---|---|---|
| 10% down | 4.125% | 85.01–90% | |
| 20% down | 3.375% | 75.01–80% | |
| 25% down | 2.125% | 70.01–75% | |
| 30% down | 1.625% | 60.01–70% | |
| 40% or more | 1.125% | 60% or less |
Source: Fannie Mae LLPA Matrix, purchase loans, effective 09/09/2026. Licence.
Read the jump between the 20% and 25% rows. The fee falls from 3.375% to 2.125% — a 1.25 point drop for five extra points of down payment. No other step on the ladder pays back anything close to that.
The second home premium is not a rate. It is a fee schedule with a cliff at 75% loan-to-value.
4Second Home vs Investment Property: The Gap Has Closed
Quick Answer: On the current fee schedule, second homes and investment properties are charged the same occupancy fee at every loan-to-value band. The remaining advantage of a second home mortgage is a higher borrowing ceiling, not a cheaper one — a distinction most brokers and bank loan officers still describe the old way.
For years the received wisdom was that vacation homes priced close to primary residences and rentals priced far above both. That stopped being true after the 2022 repricing. Compare the three occupancy types side by side.
| Occupancy | Max LTV | Min Down | Fee at Max LTV | Cash-Out Max | Units |
|---|---|---|---|---|---|
| Primary residence | 97% | 3% | 0.000% | 80% | 1–4 |
| Second home | 90% | 10% | 4.125% | 75% | 1 only |
| Investment property | 85% | 15% | 4.125% | 75% | 1–4 |
Sources: Fannie Mae Eligibility Matrix (Aug 2026); Fannie Mae LLPA Matrix (Sept 2026). Licence.
The fee column is identical down the second home and investment rows, band for band. What still separates them is leverage: you can borrow 90% against a second home and only 85% against a rental, and the rental can be a multi-unit building while the second home cannot.
Practically, that changes the question. If you plan to rent the place out most of the year, calling it a second home saves you nothing on the fee and exposes you to occupancy fraud. The honest classification is usually also the cheap one.
5What a Second Home Mortgage Costs Up Front
Quick Answer: On a $600,000 second home with a 740 credit score, total price adjustments run from $26,325 at 10% down to $4,050 at 40% down. The steepest single improvement is between 20% and 25% down, where the bill falls by $9,150 — before you count any gift funds toward the down payment.
The table below stacks the occupancy fee on top of the credit-score adjustment for the same borrower at five down payments. These are the numbers a lender either collects in cash or buries in your rate.
| Down Payment | Loan Amount | Total Fee % | Fee in Dollars |
|---|---|---|---|
| $60,000 (10%) | $540,000 | 4.875% |
$26,325 |
| $120,000 (20%) | $480,000 | 4.250% |
$20,400 |
| $150,000 (25%) | $450,000 | 2.500% |
$11,250 |
| $180,000 (30%) | $420,000 | 1.750% |
$7,350 |
| $240,000 (40%) | $360,000 | 1.125% |
$4,050 |
Illustrative: 740–759 FICO, purchase. Fee percentages from Fannie Mae LLPA Matrix, 09/09/2026. Licence.
Look at the middle two rows again. Finding an extra $30,000 for the down payment removes $9,150 of fees, so roughly 30 cents of every additional dollar comes straight back. Nothing else on a second home mortgage returns at that rate.
6Credit Score, Reserves and Debt Load
Quick Answer: Credit score moves the fee independently of occupancy. At 90% LTV, a 780 score pays 0.250% where a 700 score pays 1.250% — a full point of loan amount. Lenders also want cash reserves and a workable ratio of debt to income after both housing payments.
Three levers sit under your control once the down payment on a second home mortgage is set.
- Credit score. On a $540,000 loan, the gap between a 700 and a 780 score is about $5,400 in fees. Scores are banded, so a few points can move you a whole tier.
- Reserves. Fannie Mae requires extra reserves when a borrower carries multiple financed properties. Expect several months of payments on both homes to sit in verified accounts.
- Total debt load. Your first mortgage, taxes and insurance all stay in the calculation. The second home payment is added on top, not substituted in.
Reserves are the one that surprises people. The money has to be documented and available, which means it cannot be the same cash you just spent on the down payment. Plan for both.

7What the Premium Costs Over Thirty Years
Quick Answer: Financed into the loan rather than paid in cash, the occupancy fee alone costs about $145 a month at 10% down and $62 a month at 25% down on a $600,000 second home. Over a full 30-year term at the current benchmark mortgage rate, that gap compounds to nearly $30,000.
Most buyers roll the fee into the loan without noticing, because it arrives as a slightly higher rate. Here is what it actually costs as it accumulates, using the 30-year fixed average of 6.76% for the week ending September 10, 2026, per Freddie Mac’s Primary Mortgage Market Survey.
| Scenario | Year 1 | Year 3 | Year 5 | Year 10 | Year 20 | Year 30 |
|---|---|---|---|---|---|---|
| 10% down |
$1,735 |
$5,206 |
$8,677 |
$17,354 |
$34,708 |
$52,062 |
| 25% down |
$745 |
$2,235 |
$3,726 |
$7,451 |
$14,902 |
$22,353 |

The first year looks harmless either way. It is the back half of the term where the two paths separate, and refinancing a second home mortgage out of the fee later usually means paying a fresh one.
8Loan Limits and When You Cross Into Jumbo
Quick Answer: The 2026 conforming limit is $832,750 in most counties and $1,249,125 in high-cost areas. Past that, a second home mortgage becomes a jumbo loan, where the fee schedule above no longer applies and each lender writes its own rules.
Resort counties are exactly where this bites. Many of the places people buy vacation homes carry high-cost limits, and many others do not, which means the same purchase price can be conforming in one county and jumbo one county over.
The FHFA set the 2026 baseline at $832,750, up $26,250 from 2025, with a ceiling of $1,249,125 in high-cost areas and the same $1,249,125 as the floor in Alaska, Hawaii, Guam and the U.S. Virgin Islands, according to the FHFA announcement. Check your specific county before you assume.
Jumbo second home terms vary widely. Some lenders want 30% down, some price second homes no differently from primary homes, and a few will not write them at all. It is worth quoting several.
9Renting It Out Without Breaking the Loan
Quick Answer: You can rent a second home occasionally. Rent it fewer than 15 days a year and the IRS does not tax the income at all. Beyond that, personal use has to exceed 14 days or 10% of rental days for the property to stay a residence for tax purposes — which is separate from what your mortgage lender allows.
Two rulebooks apply here and they do not match. The lender cares about occupancy and qualifying income. The IRS cares about the split between personal and rental days.
IRS Topic 415 sets the personal-use test: the place counts as a residence if you use it personally for more than the greater of 14 days, or 10% of the days it is rented at fair market rent. Rent it fewer than 15 days in the year and you report none of the income and deduct none of the rental expenses.
A modest summer let sits inside both rulebooks. A property listed year-round on a short-term rental platform does not, and that mismatch is what threatens the second home mortgage later.
10The Bottom Line
Quick Answer: Treat the second home mortgage as a fee problem, not a rate problem. Get to 25% down if you possibly can, keep the score above 760, confirm your county limit, and be honest about occupancy. Then expect the same underwriting timeline as any other loan.
Our take: the 75% loan-to-value line is the decision that matters most, and almost nobody frames the purchase around it. Everything else — shopping lenders, timing a rate lock, choosing a term — moves the number by less.

11Frequently Asked Questions
1. How much down payment do you need for a second home?
Ten percent is the minimum on a conventional loan, because Fannie Mae caps one-unit second home purchases at 90% loan-to-value. Below 20% you also pay private mortgage insurance. Most buyers do better at 25% down, where the occupancy fee drops from 3.375% to 2.125% of the loan amount.
2. Are second home mortgage rates higher than primary home rates?
Effectively yes, but the premium is charged as a one-time fee rather than a published rate. Fannie Mae adds 1.125% to 4.125% of the loan amount depending on loan-to-value. Lenders usually convert that into a higher rate, which is why quotes vary so much between lenders on identical second home files.
3. Can you use an FHA or VA loan for a second home?
No. FHA, VA and USDA loans all require the property to be your primary residence. Conventional financing through Fannie Mae or Freddie Mac is the standard route for a second home mortgage, with jumbo lenders handling anything above the county conforming limit.
4. What is the difference between a second home and an investment property?
A second home is one unit, occupied by you part of the year, with no rental income used to qualify. An investment property can be one to four units and is bought to rent out. On the current fee schedule both pay the same occupancy adjustment, but second homes can borrow up to 90% versus 85% for rentals.
5. Can you rent out a second home?
Occasionally, yes. Fannie Mae allows rental income on a second home as long as it is not used for qualifying. For taxes, renting fewer than 15 days a year means you report no income at all. Regular year-round renting makes the property an investment property in both rulebooks.
