Second Home Mortgage Requirements: What You Need to Qualify in 2026

If you already own a home and are thinking about buying another one, you’re in good company. In June, 13% of home purchases were second homes or investment properties, according to the National Association of Realtors.[1] 

Whether you've been eyeing a beach cottage, a future retirement spot, or a bigger place to live while you rent out the house you've outgrown, you have options for financing that second home.

The thing to keep in mind is that not everything you might consider a "second home" counts as one in a lender's eyes — it depends on how you'll use the property and how often you'll actually live there. How a lender classifies your new property can change your down payment, interest rate, and required cash reserves considerably. 

Below, you'll find out what constitutes a second home (and what doesn't), the qualification requirements for a second home mortgage, and how to apply when you're ready.

What counts as a second home?

A second home is one you purchase for personal use and own in addition to your primary residence. Many people buy second homes to use as a vacation spot for weekend getaways or a future retirement home. 

For a second home to remain such to a lender, you must occupy the property for part of the year. The property must also remain in your control, meaning you can’t pass it off to a rental management company.

The key here is that a second home is meant to be a getaway from your main home where you spend most of your time.   

What can you use a second home for?

Wondering if your intended use for a second home fits a lender’s definition? Here are some lender-acceptable second home uses:

• A vacation getaway, such as a beach house, lakeside cottage, or mountain cabin
• A home located closer to your place of employment to use during the work week
• A future retirement spot used part-time for now
• A future home for a child to use during or after college, used part-time now

If you primarily want to rent out the space for income, a lender will consider the home an investment property. This distinction is important because it changes the loan interest rates and minimum qualifications. 

Second home vs. investment property

A second home and an investment property are not the same in a lender’s eyes, mainly because their purposes are different. A second home is for personal use and enjoyment, while an investment property generates income.

“The line comes down to intended use and control, not just how often you visit,” says Chris Kuclo, branch manager at Best Interest Financial, who has over 15 years of experience in mortgage lending. “A second home has to be available for the borrower's personal use year round, generally in a location that makes sense as a vacation or seasonal property, and it cannot be run through a rental pool, timeshare, or property management arrangement that gives someone else control of the calendar.”

Risk level also varies between second homes and investment properties. While both property types are riskier than a primary residence, investment properties are riskier than second homes. Because of their higher risk level, investment properties come with higher rates and typically require 15–25% down upfront. Second home loans usually only need a 10% down payment and come with more favorable rates. 

Investment properties let you use projected rental income (about 75% of documented market rent) to qualify for the loan. As soon as you use rental income to qualify, a lender flags the home as an investment property, because second home mortgages don't count rent as qualifying income.

Any of the following actions can tip off to a lender that the property is actually an investment property — and that it will be underwritten as one:

• Using the projected rental income to qualify for the loan
• Renting the property out full-time or long-term
• Putting the property under the control of a management company or rental pool

Misrepresenting the property’s intended use to lenders is called occupancy misrepresentation, which is a form of fraud that can have serious financial and legal consequences. 

What if you're buying a new home but keeping your current one?

Let’s say you’re planning to buy a second home as your new primary residence while keeping your current home to rent out. In this case, lenders consider the new home as a primary residence and will underwrite the loan as such, meaning you can buy the home for only 3–5% down. 

When you apply for a mortgage in this situation, you can also use up to 75% of the projected rental income to factor into your DTI calculation. But to do so, you’ll need to take some extra steps.

Second home mortgage requirements

Typically, second home mortgages have stricter requirements than those for a primary residence but more lenient requirements than those for an investment property. In any scenario, however, having compensating factors, such as a high credit score or larger down payment, can offset weaker areas of your financial profile. 

Here’s a comparison of each occupancy type and how their mortgage qualifying standards differ at a glance.

Down payment

You may think that a second home requires a hefty 20% down payment, but that’s not necessarily correct. For a true second home conventional mortgage, you only need to put down 10%. 

To avoid private mortgage insurance (PMI), though, you'll need to put down the full 20%. A larger down payment also earns you a better rate and helps offset weaker areas of your financial profile.

“A smaller down payment also pushes you into a higher LLPA [loan-level price adjustment] tier, which raises the rate itself on top of the added MI [mortgage insurance] cost…” says Kuclo. “We generally counsel clients to run the full monthly cost, MI included, against a 20 percent down scenario before deciding."

To compare, down payment minimums for primary residences can go as low as 3–5%, while those for investment properties can jump to 15–25%.

Credit score and DTI

DTI, or debt-to-income ratio, measures your total monthly debts, including any housing costs, against your total monthly earnings. DTI and credit score are two important metrics lenders look at when reviewing mortgage applications. 

The floor for second home credit scores sits at 680–720, though you might be able to get away with 640 if you have other stronger areas, such as a low DTI or larger down payment. Investment properties have the strictest credit requirements, often asking borrowers for a 700 score or higher.

DTI can stretch to about 45% for second homes, even up to 50% with compensating factors.[2] Note that lenders include the new second home mortgage payment, along with your primary mortgage payment, in the DTI calculation. If both payments use up too much of your income, a lender may find you too risky to lend to.  

Income requirements

That means, for a true second home, you can’t use anticipated Airbnb or other seasonal income to qualify for a mortgage. Your qualifying income must come from other reliable earnings. 

Cash reserves

Cash reserves are liquid assets — or assets easily converted to cash — that are left over after paying closing costs and your down payment. Examples include cash savings, funds collected from selling an asset, and money withdrawn from an account.[3] 

To get a second home mortgage, lenders like borrowers to have enough liquid reserves to cover at least two months of mortgage payments if income is interrupted. These payments must cover principal, interest, taxes, and insurance (PITI) costs for each month — enough for both homes. If you have a weaker profile, a lender may require more reserves, and investment properties call for a minimum of six months.  

Property requirements

To count as a second home, the property in question must meet some requirements. The property must be:

• A one-unit dwelling
• Suitable for year-round use
• Occupied by the borrower for at least part of the year
• Solely owned and controlled

Timeshares, shared-ownership arrangements, and multi-unit dwellings are not allowed.[4]

Occupancy and usage requirements

Your second home must be a place that you’ll live in for more than half of a calendar year. But what about the rest of the year? Can you rent it out then? You can, but only occasionally and for the short term. Any long-term rental — or property run by a management company — changes its classification to an investment property.[4]

To count as a second home, the property needs to be located in an area that’s a reasonable distance from your primary residence.[5] 

The true cost of buying a second home

The cost of a second home involves more than the listing price. Besides a down payment and closing costs, there are other expenses that can catch some homeowners off guard.

Loan costs

Here’s a breakdown of the different costs involved with a mortgage on a second home:

• Interest rate: Typically, second home rates run 0.25–0.75% higher than those for a primary residence, and as of July 16, 2026, 30-year mortgage rates are 6.55% for a primary home, according to Freddie Mac.[6] Borrowers who have strong credit and a 20% down payment tend to get the best rates. Keep in mind that lenders can price in any perceived added risk to the rate, depending on occupancy, down payment size, and credit score, so the exact rate gap varies. Working with a broker who can shop around at multiple lenders on your behalf can help you snag the best rate offer. 
• Closing costs: Expect closing costs to run about 2–5% of the loan balance.[7] Along with the down payment, you’ll owe closing costs on closing day (unless you roll them into the loan total). Closing costs cover the expenses to underwrite the loan, lender fees, and other third-party costs like getting the home appraised and running a title check. 
• PMI: If you don’t make at least a 20% down payment, you’ll be on the hook for mortgage insurance.[8] PMI costs more on a second home than it does on a primary residence.

Other costs of owning a second home

Besides the mortgage itself, here are other expenses to factor into the full cost of owning a second home:

• Insurance: Kuclo shares that one of the biggest shocks for homeowners is insurance, “... especially in coastal, wildfire, or flood-prone areas where premiums on a second home can run well above what buyers pay on their primary.”
• Property taxes: Because second homes don’t qualify for a homestead exemption, the tax bill can be much higher than a similarly priced primary home in the same state.
• HOA and condo assessments: “Condo and HOA buyers are often blindsided by special assessments, particularly as more associations respond to updated building safety and reserve funding requirements,” says Kuclo.
• Maintenance and oversight: Don’t forget about upkeep costs with a second home. Who will oversee the property during the months you’re not there? Paying for maintenance and ongoing upkeep are costs you should factor into your budget from the start.

How to get a second home mortgage

Ready to dive into the process of buying a second home? Here’s exactly how to secure the financing.

Types of second home mortgage loans

You have a few choices for financing a second home:

• Conventional loan: This is a standard route to financing a second home, and works similarly to how you financed a primary home. This option works best for people buying a property priced below conforming loan limits who meet lender requirements.
• Jumbo loan: This loan type works best for those buying a luxury property — perhaps in a more expensive cost of living area — that costs more than the conforming loan limit. For 2026, the conforming loan limit sits at $832,750 for most U.S. areas.[9] 
• Adjustable-rate vs. fixed-rate mortgage: For either of the above options, you can select a mortgage with an adjustable rate, meaning it’s subject to changing over the loan term, or a fixed rate, meaning the rate stays stable instead. 
• Interest-only mortgage: An interest-only mortgage allows you to save some money upfront by only paying interest for a set time. But these loans become more expensive once that time expires and you start paying back principal and interest. 

Can you use an FHA or VA loan to buy a second home?

Both the FHA and VA are programs that help finance primary homes, making them ineligible for financing a true second home.

However, there is a workaround with VA loans, thanks to VA loan entitlement.

Using your home equity to buy a second home

If you’ve built up a lot of equity in your primary home, an alternative is tapping those funds through a home equity loan, HELOC, or cash-out refinance to pay for the down payment or entire second home purchase. 

While this can be an effective way to buy a second home, keep in mind the tradeoff: you’d be securing more debt against your primary home.

Steps to get approved

Shop around with a few lenders on your own or with the help of a broker, comparing their rates, fees, and terms and apply for pre-approval. 

"Get pre-approved specifically as second-home financing from the start, since running numbers as if it were a primary residence will give you a misleading picture of your rate and payment,” says Kuclo.

Comparing loan estimates from several lenders can help you more easily stack lenders and their offers against each other to find the best one. This is more difficult to do with verbal quotes.

And be sure to budget for the entire cost of owning a second home, not just the mortgage itself. Having a clear picture of total expenses from the start can help you set a realistic budget.

Kuclo also advises aspiring second home owners to speak with a loan officer early on to confirm your occupancy status, DTI, and reserves before going under contract. He also warns borrowers to avoid the common misstep of assuming future rental income can help them qualify for a second home mortgage. Remember, doing so tips the home over into investment property classification.

FAQs

If I'm moving and renting out my current home, is my new home a second home? 

No. If you'll live in the new home, it's your primary residence — which usually means a lower down payment than a second home. The catch is your old mortgage: to count that home's rental income, lenders generally want a signed lease and a deposit received, and if you have less than 30% equity, the income often can't be counted at all.

Can I use an FHA or VA loan to buy a second home? 

Not for a true second home — both are primary-residence programs. FHA allows a second loan only in narrow cases (like relocating for work or outgrowing your home), and the new property must be your primary residence. VA works similarly, though second-tier entitlement lets a veteran keep a VA-financed home as a rental and buy a new primary. For a vacation home, plan on conventional financing.

How close can a second home be to my primary residence? 

There's no fixed federal mileage rule, but the home has to make sense as a second home — usually a vacation or seasonal spot. Lenders look closely at a "second home" in the same town as your primary, since it can look like an investment property or an unnecessary purchase. If it's nearby, be ready to explain the genuine personal-use reason.

Does renting out my second home affect my taxes? 

It can. Under the IRS "14-day rule," if you rent your second home 14 days or fewer per year, you generally don't report that rental income. Rent it longer and you have to report it, but you can also deduct expenses like lawn care, cleaning, and home maintenance.
