The Quick Read: The lender sizes the loan by running two tests and taking the smaller result. The first test is leverage: how much the property’s value supports. The second is payment capacity: how much of your income can go toward a second housing payment. On a second home, leverage tops out at 90% of the lower of price or appraised value. Most files end up limited by the payment test, not the leverage cap.
Key Takeaways
- A second home is a one-unit property you occupy part of the year and that is not run as a rental business.
- Leverage on a second home tops out at 90% LTV (loan-to-value, the loan as a share of the home’s value). A primary residence can go to 95% or 97%.
- Your current home payment and the new vacation payment both count against your income. Rent from the vacation home does not offset the new payment.
- Mortgage insurance applies above 80% LTV. It cancels at 80% on request and ends automatically at 78%.
- The loan is the smaller of what the value allows and what your income allows. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What Makes a Vacation Home a “Second Home”?
A second home is a one-unit property you personally occupy for part of the year. It must be suitable for year-round use, and you must control it exclusively. That is the line between a second home and an investment property. Occupancy decides the leverage, so it decides the loan size.
Conventional payment estimate
The starting figures are an example price at the first-time buyer’s minimum down payment. Replace them with yours.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a conventional loan quote.
Estimate seeded at the low end of Fannie Mae’s published range (0.58%–1.86% a year); the insurer prices the actual premium on the score and the leverage. Applies only above 80% loan-to-value.
Illustrative starting assumptions: a $350,000 price, the first-time buyer’s minimum down payment, a thirty-year term at the current Freddie Mac benchmark, mortgage insurance at the low end of Fannie Mae’s published range, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a conventional loan quote; your rate is set by the lender at lock. The mortgage insurance figure is an editable estimate seeded from Fannie Mae’s published typical range, not a premium quote; the insurer prices the actual premium, and the cancellation month assumes scheduled payments with no extra principal and no change in value. Taxes, insurance and dues are editable estimates; closing costs are not included. Conforming loan limits apply by county. Licensed in sixteen states for consumer mortgages.
The agencies’ guidelines add detail. Freddie Mac’s Seller/Servicer Guide section 4201.12 says the home must be available primarily for your own personal use and enjoyment, meaning more than half the calendar year. It must sit somewhere it can reasonably function as a second home. Timeshares and shared ownership are out.
Short-term renting is allowed in some cases. It stops being allowed if the home sits in a rental pool that requires renting, gives a management company control of occupancy, or shares revenue with a developer.
People ask about a mileage rule, such as 100 miles from your main home. The agency text does not set one. The test is whether the property functions reasonably as a second home. Some websites cite a distance rule anyway. Skip it.
Across the wholesale programs Lendmire places files with, the occupancy declaration on the application is where this starts. You declare the property as a second home. Everything downstream, from leverage to pricing to reserves, follows that declaration.
Where Do Second Homes Sit Against Other Occupancy Types?
Second-home leverage sits between a primary residence and an investment property. The table uses the leverage caps from the conventional programs Lendmire works with.
| Occupancy | Max LTV (purchase) | Units |
|---|---|---|
| Primary, first-time buyer, fixed rate | 97% | 1 |
| Primary, standard | 95% | 1 to 4 |
| Second home | 90% | 1 |
| Investment, one unit | 85% | 1 |
Those caps are subject to lender guidelines and full file review. They are ceilings, not promises. Your credit score, your ratios, and the appraisal all push the actual number lower.
You will pay more than you would on a primary home. Fannie Mae applies a loan-level price adjustment (LLPA, a risk-based pricing add-on) to certain second-home loans. It stacks on top of any other adjustments. Pricing runs higher than a primary residence with the same credit and LTV. Your Loan Estimate shows the actual terms.
More on the program side: Lendmire’s conventional loan programs cover the primary-residence and second-home lanes, and the rules above apply on both.
Gate One: How Does Leverage Set the Ceiling?
Leverage sets a ceiling on the loan. The lender takes the lower of the purchase price or the appraised value. Then it applies the second-home cap of 90%. The Fannie Mae Eligibility Matrix states that 90% maximum for a one-unit second home purchase.
Run the numbers on a simple case, using percentages of price. You contract at 100% of price. The appraisal comes in at 100% too. The maximum loan is 90% of price. You bring at least 10%, plus closing costs.
Now the appraisal comes in at 95% of price. The lender uses the lower number. The maximum loan is 90% of 95%, which is 85.5% of price. Your cash into the deal rises to 14.5% of price. You either bring the difference, renegotiate, or walk.
That is the price-versus-appraisal squeeze. It surprises buyers in resort areas, where contract prices can run ahead of comparable sales. A seasonal home may also need an appraisal comparable with similar seasonal limits, which Freddie Mac’s guide calls for to show marketability.
Credit score matters here too. Wholesale conventional programs generally start at a 620 decision score. The score and LTV interact on a grid. A borrower at the minimum score may find the top leverage is not available, and pricing steps up as the score falls.
What Does Mortgage Insurance Do on a Second Home?
Mortgage insurance applies on any conventional loan above 80% LTV. A second home at 90% leverage carries it. Published typical annual premiums run from 0.58% to 1.86% of the balance. That is a range, not a quote. Your score, your LTV, and the loan terms decide where you land. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Two cancellation rules protect you. You can ask to cancel at 80% of the original value, with good payment history, no subordinate liens, and no decline in value. The servicer must end it automatically at 78%. The premium is part of the qualifying payment, so it also feeds Gate Two.
Gate Two: How Does Your Income Set the Ceiling?
Your income sets the second ceiling through the debt-to-income ratio (DTI, your monthly debts as a share of gross monthly income). The qualifying payment for the vacation home is principal, interest, taxes, insurance, and HOA dues, plus mortgage insurance if it applies. All of it counts in full.
The lender then adds everything else. That means your current housing payment, car loans, student loans, and card minimums. Rent from the vacation home does not offset any of it. Fannie Mae’s rules let a loan stay a second home even if rental income exists, as long as that income is not used to qualify.
The ceilings come from Fannie Mae Selling Guide B3-6-02. Manually underwritten loans cap total DTI at 36%. That can stretch to 45% if you meet the score and reserve requirements in the Eligibility Matrix. Loans run through automated underwriting can go up to 50%. The automated finding governs most files.
Here is how to work it backward, with income as 100 units:
1. Start with the ceiling. Take 45% as a manual-underwriting stretch case, so total debts can be 45 units.
2. Subtract your current home payment, say 20 units.
3. Subtract other monthly debts, say 5 units.
4. What remains is 20 units. That is the most the vacation home payment, taxes, insurance, HOA, and mortgage insurance can total.
Under an automated 50% ceiling, the same borrower would have 25 units left. Same person, same debts, different underwriting path. That difference is why the finding from automated underwriting matters so much.
Then the lender works from payment capacity to loan amount. Taxes, insurance, HOA dues, and mortgage insurance eat part of the budget before any principal and interest is left. Costly insurance or hefty HOA dues shrink the loan, even when your income looks strong.
The qualifying rate on a fixed-rate loan is the note rate. If a seller or builder buys down the rate temporarily, the lender qualifies you without the bought-down rate. The buydown does not stretch your ratio.
Which Gate Binds? Three Borrower Profiles
Whichever test gives the smaller loan wins. Here are three contrasting profiles.
| Borrower | What binds | Why |
|---|---|---|
| Strong income, little debt | Leverage | Payment room exists; 90% cap stops the loan |
| Solid income, heavy existing debts | Payment | DTI runs out before 90% LTV |
| Strong income, low appraisal | Value | Lower appraisal shrinks the loan |
Many buyers expect leverage to be the limit. Often it is the payment test. A second home adds a whole housing payment on top of the first one. The ratio fills up fast.
This is a genuine toss-up when a buyer sits near the line. Paying off a car loan can add more room than a larger down payment. A co-borrower with income can move the ratio more than either. Run both before picking a lever.
What Reserves Do Lenders Want?
Reserves are liquid assets left in your account after closing. For loans run through Fannie Mae’s automated underwriting, Selling Guide B3-4.1-01 sets reserves at two months for a second-home transaction. Manually underwritten loans take their reserves from the Eligibility Matrix. Required reserves also vary with the number of units, the amortization type, and how many other financed properties you own.
Some sources of funds do not count. The guide lists non-vested funds, personal unsecured loans, and cash proceeds from a cash-out refinance of the subject property. Gifts can help with reserves in some cases. Gifts of equity cannot.
Own several financed properties and the reserve bar rises. Fannie Mae’s multiple financed properties rule caps a second-home borrower at 10 financed properties on an automated loan. It counts properties, not mortgages. It includes a financed principal residence, and jointly financed properties are counted once.
Where the Rule Breaks: Edge Cases
The standard sizing logic bends in several named situations.
- Two-unit “vacation” property. Freddie Mac treats a 2-unit home as an investment property, not a second home. Fannie Mae restricts second homes to one unit. Different occupancy, different leverage.
- Rental pools and management control. A pool that requires renting, or one where a manager controls occupancy, fails second-home status.
- Seasonal or non-winterized homes. These need a comparable sale with similar seasonal limits.
- Accessory dwelling units. Fannie Mae’s appraisal policy says a second home cannot have an ADU.
- Manufactured homes. They use a separate LTV table and must go through automated underwriting.
- Affordable programs. Home Possible and similar programs cover primary residences only. Community Seconds does not allow second homes.
- Co-op shares. Cash-out refinances on second-home co-ops are not permitted.
- Government loans. FHA and VA loans generally do not finance second homes.
The jumbo question comes up when the loan outgrows the conforming limit. Then the jumbo lanes take over with their own rules. Lendmire’s piece How a Jumbo Lender Sizes the Down Payment on a Second Home covers that side.
What Happens After the Loan Is Sized?
Several steps follow. The file runs through automated underwriting. The appraisal comes in. Your lender verifies assets and income. And the lender’s occupancy checks do not stop at application.
You sign a second home rider at closing. Per Freddie Mac’s servicing guide, the security instrument and rider require you to keep the property available primarily as a residence for personal use and enjoyment for at least one year.
Late-stage changes matter. On a manually underwritten loan, a recalculated DTI up to 45% triggers re-underwriting. So don’t open a new credit line or finance furniture between approval and closing.
Your Loan Estimate and Closing Disclosure show loan terms, projected payments, and closing costs. Compare them line by line.
Occupancy honesty matters too. Calling a rental property a second home is not harmless. A Federal Reserve Bank of Philadelphia paper hosted by the FDIC found that borrowers who misrepresented occupancy defaulted at nearly twice the rate of similar owner-occupants. Lenders scan for it. Fannie Mae’s occupancy materials list red flags, such as an insurance policy that does not cover personal property.
Levers That Raise the Loan Amount
You have a few moves. Pay down or pay off installment debt before applying. Add a co-borrower with income. Put more down so mortgage insurance drops away or shrinks. Choose a property with lower HOA dues, or one that carries lower insurance. And hold off on new credit.
Reserves help too. More cash in the bank can move a manual-underwriting file from the 36% ceiling toward 45%.
If your plan involves tapping home equity later, see Lendmire’s explanation of how a lender sizes a conventional cash-out refinance on a second home.

Frequently Asked Questions
Can rental income help me qualify for a vacation home loan?
No. The loan can still be a second home if rent exists, but the rent cannot count toward qualifying. The full payment goes against your income. If you plan to run the property mainly as a rental, it falls into a different loan category with different leverage.
What is the minimum down payment on a second home?
The leverage cap is 90% LTV on a purchase, which points to 10% down at minimum. The real number depends on the appraisal, your credit score, and your ratios. A low appraisal pushes the cash requirement higher. All figures are subject to lender guidelines and full file review.
Can I use an FHA or VA loan for a vacation home?
Generally no. Government-backed loans are aimed at a primary residence. Conventional financing is the usual route for a second home. Jumbo lanes apply if the loan exceeds the conforming limit.
Does the property have to be a certain distance from my main home?
No agency distance rule appears in the Fannie Mae or Freddie Mac guidelines. The property must be somewhere it can reasonably function as a second home, and you must occupy it for part of the year.
Will I pay mortgage insurance?
Usually, yes, when leverage is above 80%. Since the cap is 90%, most second-home buyers who put down the minimum will. It cancels at your request at 80% of original value, subject to conditions, and ends automatically at 78%.
