The Quick Read: The new loan is capped at a percentage of appraised value, and the cap depends on whether you take cash out. A no-cash-out refinance on a one-unit second home can reach 90% of value. A cash-out refinance tops out at 75%. Those ceilings sit below a primary residence, so a second home takes more equity and more cash in reserve. Every figure here is subject to lender guidelines and full file review, and none of it is a commitment to lend.
Key Takeaways
- The maximum loan is appraised value times the ceiling for your transaction type. Payoff, closing costs and any cash you want must fit inside it.
- Rate-and-term (limited cash-out) on a one-unit second home: up to 90% of value. Cash-out: up to 75%.
- A primary residence gets more room: 80% on cash-out, 95% to 97% on a rate-and-term refinance in the right cases.
- Mortgage insurance applies above 80% LTV. It can be cancelled at 80% of original value and ends automatically at 78%.
- The property must actually work as a second home. A rental in disguise falls into a different, lower-leverage category.
What Is a Second Home Refinance, Mechanically?
A second home refinance replaces the loan on a home you use part of the year but do not live in full time. It is underwritten as a consumer mortgage, so the Loan Estimate and Closing Disclosure rules apply.
Refinance savings and break-even estimate
The starting figures are an example value with a balance in proportion and a placeholder for costs. Replace them with yours, and enter the current rate from your statement.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $245,000 current balance, a current rate you enter and a remaining term seeded at twenty-five years, closing costs seeded at $5,000 as an editable placeholder (not a fee quote) and rolled into the new loan, a thirty-year term at the current Freddie Mac benchmark, 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 new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates.

The occupancy label comes first because it sets the ceiling. Occupancy is also where files get questioned. Across the conventional programs Lendmire arranges through wholesale lenders, the same refinance on a primary residence, a second home and a rental lands at three different leverage caps.
Lendmire's conventional loan programs follow the same structure on a second home as on a purchase. You need a one-unit home with year-round livability and a lender who can run it through automated underwriting. The wholesale floor is a 620 decision score, and the automated ratio ceiling is 50%.
The second step is classifying the transaction. There are two buckets, and the label drives everything that follows:
- Rate-and-term (limited cash-out). The new loan pays off the existing first mortgage, closing costs and prepaids, plus a purchase-money second lien. Only incidental cash comes back.
- Cash-out. You take real cash, or you pay off a junior lien that was not used to buy the home. The lower ceiling applies.
A line of credit drawn for a kitchen remodel and then paid off in a refinance is the classic misclassified item. Pay it off at closing and the file can flip from rate-and-term to cash-out. The cap falls from 90% to 75%, and the numbers stop working.
How the Maximum Loan Gets Built
The maximum equals appraised value times the ceiling. Then subtract what the loan has to cover. Whatever falls above that line has to come from your own cash or stay unborrowed.
Run it in percentages. Say a second home appraises at 100 units of value. At a 90% ceiling, the new loan can reach 90 units. Everything the loan must pay off fits inside that: the existing balance, closing costs, prepaids and any purchase-money second. If those add up to 85 units, there is room for a small cushion. If they add up to 93 units, you are 3 units over and must bring cash to closing.
Cash-out works the same way at a lower line. At a 75% ceiling on the same 100 units, the loan reaches 75. A borrower with an existing balance near 60 units can pull roughly 15 units, less costs. A borrower at 72 units has almost nothing to take out.
Two things shrink the number from underneath:
1. The appraisal. Value is the denominator. A lower appraisal drops the ceiling and the loan with it. Appraisal reconsideration, with recent comparable sales and condition notes, is routine when value comes in light.
2. Other debt. Your second-home payment sits on top of your primary housing payment. Both count toward the total ratio.
Appreciation works in your favor only through the appraisal. The ceiling does not move. More value means more room under the same percentage.
What the Agency Rules Say
The agencies set these ceilings, and they are readable. Fannie Mae's Eligibility Matrix shows 90% LTV for a one-unit second-home limited cash-out refinance, and 75% for cash-out. The same matrix shows a one-unit primary residence at 80% for cash-out. Freddie Mac's Guide section on LTV limits lands in the same place. The cap is 90% for second-home purchases and no-cash-out refinances, and 75% for cash-out, for loans that receive an Accept finding. Terms depend on the lender's guidelines, the property type, the leverage, and a full review of the credit profile.
| Transaction | Primary residence | Second home (one unit) |
|---|---|---|
| Purchase | 95% (97% first-time buyer) | 90% |
| Rate-and-term refinance | 95% (97% in some cases) | 90% |
| Cash-out refinance | 80% | 75% |
Here, LTV, CLTV and HCLTV measure the first mortgage alone, the first plus other liens, and the first plus the full line of credit. The cap applies to each measure. A second lien or an open HELOC that is not paid off can use up the room.
Manual underwriting is largely off the table for second homes. Freddie Mac shows manual second-home cells as not available, and Fannie Mae requires an Approve/Eligible finding from its automated system, except for high-LTV refinances. In practice, the automated finding decides the file.
Where Second Homes Break the General Rule
Several situations change the answer. Know them before you apply, not after the appraisal.
Occupancy and Rental Use
Fannie Mae's second-home definition requires a one-unit dwelling suitable for year-round use. You occupy it for part of the year and keep exclusive control. It cannot be a timeshare, and no agreement can give a management firm control over occupancy. Rental income can be identified but cannot be used to qualify.
Freddie Mac's second-home section adds that the home must be available primarily for personal use, meaning more than half the calendar year. Short-term rental is tolerated only without rental pools, revenue sharing with a developer, or a manager controlling occupancy. If a property is really used as a rental, it is treated as an investment property instead, at a lower ceiling. Reviewers also look at red flags, such as a second home sitting close to your primary residence.
Two-Unit Properties
A two-unit property used as a second home is treated as an investment property under Freddie Mac. It does not get the 90% line. It is not a second home on paper, whatever you intend to do with it.
Condos, PUDs and Manufactured Homes
Condos and PUDs generally work as one-unit properties, but the project review adds its own checks. Manufactured homes carry their own, more restricted limits. Ask for the current figure before assuming the standard ceiling applies.
Seasonal Access
When a home has seasonal limits on year-round occupancy, Freddie Mac asks the appraiser to include at least one comparable sale with similar seasonal limits. A mountain cabin with a closed road in winter needs a comparable that proves the market.
Programs That Do Not Reach Second Homes
HomeReady and Home Possible are for principal residences. The 97% first-time-buyer leverage on a purchase also applies to a primary home only. Government streamline programs such as FHA Streamline and the VA IRRRL are likewise tied to the home you live in. The conventional route is the one that covers second homes.
Reserves, Seasoning and Credit
Reserves. Fannie Mae's minimum reserve rules set two months of housing payment on a second-home transaction in its automated system. Acceptable sources include checking and savings, stocks, bonds, mutual funds, vested retirement funds and the cash value of vested life insurance. Reserves are money that stays after closing. They are not the down payment, and they are not the cash you bring to a refinance that comes in over the cap. Owning other financed properties raises the requirement.
Seasoning for cash-out. The existing first mortgage must be at least 12 months old, measured note date to note date. You must have been on title for six months. Delayed financing, inheritance and legal-award exceptions exist. These tests do not usually decide a rate-and-term refinance on a second home, but confirm your own file.
Credit and ratios. Wholesale conventional programs start at a 620 decision score, and many lenders add their own higher floors. The automated finding governs, with a 50% total ratio ceiling. Higher scores and more equity improve the file. Waiting periods after credit events are agency rules: four years from a chapter 7 discharge, seven from a foreclosure, and four from a short sale or deed-in-lieu, shorter with documented extenuating circumstances.
Cash back on a no-cash-out refinance. Incidental cash is allowed but capped at a small percentage of the new balance or a small fixed amount. Take more and the loan is reclassified as cash-out.
Mortgage insurance. Above 80% LTV, mortgage insurance is required. You can request cancellation at 80% of the original value with good payment history, no subordinate liens and no decline in value. The servicer must end it at 78% under the Homeowners Protection Act. Published typical annual premiums run from 0.58% to 1.86% of the balance. That is a range, not a quote. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
When You Are Over the Cap
A refinance can fail on the number with nothing wrong in the file. Say the payoff and costs total 93% of a 100-unit appraisal and the ceiling is 90%. You have four practical options:
1. Bring cash to closing. This is a cash-in refinance, and it brings the balance down to the cap.
2. Challenge the appraisal. Submit recent in-area sales and condition adjustments through appraisal reconsideration.
3. Wait. Pay the balance down, or let value catch up, then reapply.
4. Skip the refinance. If the goal is cash and your existing first mortgage is worth keeping, a separate second lien or line of credit may fit better. It adds a payment and counts toward CLTV.
There is also the reverse case. A borrower who wants cash but sits above 75% after the payoff should not assume the rate-and-term cap rescues them. The 90% line only applies if the loan truly takes no real cash out.

Documents Lenders Ask For
Expect the usual set: income and asset statements, the current mortgage statement, homeowners insurance, tax and HOA information, and occupancy and ownership disclosures. Expect questions on how you use the home. Clean answers there, such as a seasonal calendar or proof you hold exclusive control, prevent the file from stalling.
Documents that cause trouble:
- HOA questionnaires that arrive incomplete.
- Insurance quotes that leave out coverage tied to the second home.
- A payoff statement for a line of credit that does not show whether it was drawn.
- Asset statements that do not cover the full reserve period.
Key Terms Defined
LTV (loan-to-value): The new loan balance divided by the appraised value of the home.
CLTV / HCLTV: The combined balance of all liens, and the same figure counting the full limit of any home equity line.
Limited cash-out refinance: A refinance that pays off the first mortgage and closing costs, with only small incidental cash back. Also called rate-and-term.
Cash-out refinance: A refinance that gives the borrower real cash, or pays off a lien that was not used to buy the home. The lower ceiling applies.
Reserves: Funds you still hold after closing, measured in months of housing payment.
Seasoning: The minimum time you have owned the home or held the existing loan before cash-out is available.
Frequently Asked Questions
Can I refinance a second home at the same leverage as my primary residence?
No. A one-unit second home reaches 90% on a rate-and-term refinance, while a primary residence can reach 95% to 97% in the right cases. On cash-out the gap is 75% against 80%. Plan for more equity on a second home.
What happens if my second home also earns rental income?
Rental income cannot be counted toward qualifying on a second home. Light, occasional rental use is tolerated if no pool, manager or revenue-sharing arrangement controls the home. A property whose real use is rental falls into the investment category, which carries lower leverage.
Can a duplex be refinanced as a second home?
Not under the agency definition. Freddie Mac treats a two-unit property used as a second home as an investment property, and Fannie Mae limits second homes to one unit. The lower investment ceilings apply.
Do I need reserves for a second home refinance?
Yes. The automated system sets two months of housing payment on a second-home transaction, measured on the full payment. Owning other financed properties can raise the requirement. Reserves must be documented from acceptable assets.
Does paying off my HELOC count as no-cash-out?
Only if the line was used to buy the home. Paying off a line drawn for other purposes generally turns the refinance into cash-out, and the 75% ceiling applies. Ask for the classification before you apply.
