The Quick Read: A conventional loan on a one-unit second home generally tops out at 90% loan-to-value, so the usual minimum is about 10% down. That is more than a primary residence, where leverage can reach 95% or 97% on the programs Lendmire places. The appraisal, your reserves, and the lender’s own overlays can push the real number higher. Everything here is subject to lender guidelines and full file review, and nothing is a commitment to lend.
Key Takeaways
- A one-unit second home is generally capped at 90% LTV on a purchase, which implies roughly 10% down.
- The 3% and 5% down programs are built for primary residences. They don’t carry over to a second home.
- Above 80% LTV, mortgage insurance applies. Gift funds help, but above 80% LTV the borrower must put in some of their own money.
- A low appraisal raises your cash requirement, because the lender uses the lower of price or value.
- Rental income from the property can’t be used to qualify, and a two-unit property is treated as an investment property.
What Is a Conventional Second Home Loan?
A conventional second home loan is a consumer mortgage, sold to Fannie Mae or Freddie Mac, on a home you will personally use but not live in full time. Think of a lake house, a mountain cabin, or a beach condo. It is not a rental property. It is also not your main address.

Lendmire is a mortgage broker. It arranges conventional loan programs through wholesale lenders, and across those programs second homes sit in their own leverage tier. The parameters are straightforward: principal residences reach 97% LTV for a qualifying first-time buyer and 95% otherwise. Second homes reach 90%. Investment property is lower still. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
The down payment is just the mirror image of that cap. If the maximum loan is 90% of the value, you bring the other 10%. Fannie Mae publishes the second-home tier in its Eligibility Matrix, which lists one-unit second homes at 90% on a purchase. Freddie Mac keeps its own table on its maximum LTV requirements page, and the second-home cap there sits in the same general range.
Why Does a Second Home Need More Down Than a Primary Home?
A second home needs more down because the agencies treat it as higher risk. When money gets tight, borrowers tend to protect the house they live in first.
So the agencies ask for more equity up front. That lowers the chance of loss on the loan.
The low-down-payment programs follow the same logic. HomeReady and Home Possible, the 3% down options, are written for principal residences. Fannie Mae’s HomeReady matrix lists the occupancy as a one-unit principal residence, or a two- to four-unit principal residence. A second home isn’t on the list. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
FHA, VA, and USDA loans work the same way in practice. They are generally for the home you live in, so they aren’t a route to a second home.
How Is the Loan Underwritten, Step by Step?
The deal works through six checkpoints, and the down payment gets set at the third. Here is the sequence as it plays out across the wholesale programs Lendmire works with.
1. Occupancy declaration. You state on the application that the property is a second home. This is a representation, and it matters. Misstating it creates problems for you and for the lender.
2. Automated underwriting. The loan runs through Desktop Underwriter or Loan Product Advisor. For Freddie Mac, the finding has to be “Accept.” The automated finding sets credit, reserve, and documentation conditions for most files. Wholesale conventional programs start at a 620 decision score, with a total ratio ceiling of 50%.
3. LTV calculation. LTV is the loan amount divided by the lower of the sales price or the appraised value. The down payment is whatever closes the gap. The appraisal therefore decides the outcome.
4. Source of funds. The lender documents where your cash comes from, including any gifts.
5. Reserves. The lender counts months of the full property payment you’d still hold after closing.
6. Pricing and mortgage insurance. Both respond to how much equity you bring.
Step three is where buyers get surprised. Say you contract at a price and the appraisal comes in under it. The lender calculates LTV off the lower number, so you either bring more cash or renegotiate. Lendmire’s piece How Much a Low Appraisal Adds to a Second Home Jumbo Loan Down Payment shows the same mechanic at a larger loan size.
What Counts as a Second Home?
Eligibility comes before the numbers. If the property doesn’t qualify as a second home, the 90% tier doesn’t apply at all. Fannie Mae’s occupancy rules set the test:
- You occupy it for some part of the year.
- It is a one-unit dwelling.
- It is suitable for year-round occupancy.
- You have exclusive control of it.
- It is not a timeshare or a rental arrangement.
- No agreement gives a management firm control over occupancy.
Freddie Mac’s Guide section 4201.12 adds that the home must be available primarily for your personal use, meaning more than half the calendar year. Freddie’s determination of whether a property is a second home is conclusive.
Two things follow. First, if the lender spots rental income, the loan can still be delivered as a second home, but that income can’t be used to qualify. Second, a property you merely use now and then isn’t automatically a second home. The lender decides.
Down Payment Tiers at a Glance
| Occupancy | Typical max LTV (purchase) | Implied down |
|---|---|---|
| Principal residence, first-time buyer, fixed rate | 97% | 3% |
| Principal residence, standard | 95% | 5% |
| Second home, one unit | 90% | 10% |
| Investment, one unit | 85% | 15% |
| Investment, two to four units | 75% | 25% |
These are the leverage caps on the programs Lendmire arranges, and they are subject to lender guidelines. A particular lender can set a tighter number than the agency cap.
How Does Your Down Payment Change Mortgage Insurance and Pricing?
More equity lowers both your insurance cost and your pricing adjustment. Below 20% down, private mortgage insurance applies. Above 80% LTV, it is required. On a second home at the 90% cap, expect it. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Fannie Mae’s loan-level price adjustment matrix has a separate second-home row, and the adjustment grows as LTV rises. The practical read: each extra slice of down payment trims a pricing cost on top of trimming the insurance. Putting 20% down avoids insurance altogether, but it isn’t the minimum. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Mortgage insurance premiums on conventional loans have published typical annual ranges of roughly 0.58% to 1.86% of the balance. That is a range for context, not a quote. Your credit score and LTV drive where you land.
Cancellation is a separate question. On a principal residence, the CFPB explains that you can ask to cancel when the balance is scheduled to reach 80% of the original value. That requires a written request, a good payment history, no junior liens, and evidence the value hasn’t dropped. Servicers must terminate it automatically at 78%. The CFPB’s framing is limited to principal residences, though. Don’t assume those same rights carry over to a second home. Check your loan documents and ask your servicer.
Where Can the Down Payment Come From?
Savings, the sale of an asset, equity from another property, and gifts all work, as long as the lender can document them. The gift rule is the one with a catch.
Under Fannie Mae’s personal gifts policy, a second home can be bought with gift funds:
- At 80% LTV or less, no minimum contribution from your own funds is required, and the whole amount can come from a gift.
- Above 80% LTV, you must contribute at least 5% from your own funds. Gifts can then supplement the down payment, closing costs, and reserves. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Since the 90% cap sits above 80%, most second-home buyers at maximum leverage need that 5% of their own money. A gift of equity can’t be used for reserves.
Common paper-trail problems tend to be the same across files. Large unexplained deposits get questioned. Retirement withdrawals need documentation of the withdrawal and the balance. Proceeds from a sale need the settlement statement. Assemble these early, before you’re under contract.
Borrowing against the equity in your main home is another route. It adds a payment, and that payment counts toward your debt-to-income ratio on the new loan. Run that before you commit.
Total Cash Is More Than the Down Payment
The down payment is only the first piece of cash to close. Closing costs, reserves, and any appraisal gap stack on top.
Reserves are measured in months of the subject property’s full payment: principal, interest, taxes, insurance, and association dues. Fannie Mae’s reserve requirements note there is no minimum for a one-unit principal residence, which is not true of a second home. For a second home, plan on a few months of payments held back. Borrowers with several financed properties are asked for more. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Picture a buyer purchasing at a price with 10% down. After the down payment, they still need closing costs, a few months of reserves, and a cushion in case the appraisal lands short. The buyer who spends every spare dollar on the 10% is the buyer most likely to stall at the reserve step. Furnishing and move-in costs come on top of all of it, though those aren’t lender requirements. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The second-home payment also counts in your debt-to-income ratio, alongside your main mortgage. With a 50% ratio ceiling on most automated findings, two housing payments can use up room fast.
Where Does the General Rule Break?
The 10% rule bends in several named cases.
Two-unit properties. Freddie Mac treats a two-unit property used as a second home as an investment property, so the investment rules apply. On the programs here, that means a 75% LTV cap on two to four units. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Cash-out refinance on a second home. The equity requirement is higher than for a purchase. On the conventional cash-out program, second homes cap at 75% LTV. That is a different question from a purchase, and Lendmire covers it in its piece How Much Second Home Down Payment a Cash-Out Refinance Funds. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Manufactured homes. Fannie Mae’s manufactured housing matrix has its own second-home limits, and they differ from site-built homes. Talk to a loan officer before assuming the 10% rule applies.
Seasonal or hard-to-reach homes. Freddie Mac allows seasonal limits if the appraiser includes at least one comparable sale with similar limits.
Short-term rental use. Renting the home occasionally isn’t an automatic disqualifier. Freddie Mac allows it as long as the property isn’t in a rental pool, doesn’t require renting, doesn’t hand a management company control of occupancy, and doesn’t share revenue with a developer. Fannie Mae bars arrangements that give a management firm control. Either way, the rental income itself can’t help you qualify.
Multiple financed properties. Reserve requirements go up. Check your lender’s treatment before you assume your current reserves are enough.
Credit events. Agency waiting periods apply: four years from a chapter 7 discharge, seven from a foreclosure, and four from a short sale or deed-in-lieu. Documented extenuating circumstances can shorten them.
Lender overlays. An overlay is a lender’s own rule that is stricter than the agency’s. Some lenders set a higher credit floor or a lower LTV cap on second homes. The agency cap is a ceiling, not a promise. Ask up front what overlays apply.
Lower or Higher Down Payment: How to Decide
Whether to put down 10% or more depends on your cash position, your reserves, and how long you’ll hold the property. There isn’t one right answer. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
| Your situation | Leans toward |
|---|---|
| Thin reserves after closing | Keep more cash, put down closer to the minimum |
| Strong reserves, steady income | Put down more to shrink insurance and pricing |
| Debt-to-income already tight | A larger down payment, which lowers the payment |
| Cash needed for repairs or furnishing | Closer to the minimum |
| Plan to hold for many years | A larger down payment often pays back |
The flip point is reserves. Putting down 20% to dodge insurance sounds smart, but if it leaves you with almost no cash after closing, you’ve swapped one risk for another. Consider an owner of a modest cabin who stretches to 20% down and then faces a roof repair in the first year. The buyer with 10% down and a cash cushion is often in the better position.
On the other side, a buyer with ample reserves and a high debt-to-income ratio may find a bigger down payment is what makes the file work at all. That is the right call when the ratio, not the cash, is the constraint.
Key Terms Defined

Reserves: Cash you still hold after closing, counted in months of the property’s full payment.
Gift funds: Money given by a relative or other eligible donor that doesn’t have to be repaid.
Loan-level price adjustment: A pricing charge that varies with factors like LTV, credit score, and occupancy.
Private mortgage insurance: Coverage on the lender’s risk that applies when you put down less than 20%.
Frequently Asked Questions
Can I put 5% down on a conventional second home?
Generally no. The 95% and 97% tiers are for principal residences. A one-unit second home is typically capped at 90% LTV, which implies about 10% down. Individual lenders may require more, subject to their guidelines.
Can a gift pay for my whole second home down payment?
Only at 80% LTV or less. Above 80% LTV, a second home requires at least 5% from your own funds, and gifts can supplement after that. Gifts aren’t allowed on investment properties, so the occupancy classification matters.
Do I need 20% down to avoid mortgage insurance?
Yes, 20% is what avoids it. It isn’t required, though. You can buy at 90% LTV and pay mortgage insurance. Whether cancellation rights apply to a second home isn’t settled by the CFPB’s principal-residence wording, so check your loan documents.
Can I count rental income from a second home to qualify?
No. Rental income from a second home can’t be used to qualify, and the payment counts in your debt-to-income ratio. The property also can’t be in an arrangement that gives a management company control over occupancy.
What happens if the appraisal comes in low?
The lender uses the lower of price or appraised value for LTV, so you’d need more cash to keep the same loan-to-value, or you’d renegotiate the price. That extra cash comes on top of closing costs and reserves.
