How to refinance your second home

If you own a second home, refinancing can change your loan terms to save you money or let you borrow equity to pay for renovations. The refinance process for a second home is similar to that for a primary residence, but some terms may differ. Learn more about refinancing a second home and explore current refinance rates to understand all your borrowing options.

Key takeaways:

• Refinancing your second home allows you to secure new mortgage terms, which can save you a significant amount of money over the life of your loan.¹
• Refinancing a second home or investment property tends to be more complicated than refinancing your primary residence.
• Deciding whether to refinance involves careful consideration of your goals, your equity position, and current mortgage rates.

What is a second home?

A second home is typically defined as a single-family home that you occupy for part of the year, in addition to your primary residence.

The following properties can qualify as a second home:

• A seasonal home, like a lake cabin, that you visit in summer and close during winter.
• A year-round-use home, like a beach house, that you rent out when you're not using it.
• A condo or apartment that you keep in a city you regularly visit for work

A second home is different from an investment property, which is a home you buy with no intention of occupying yourself.

Why refinance your second home?

Here are several reasons you may want to refinance your second home:

• To reduce your mortgage interest rate.
• To modify your loan term or reduce your monthly payments.
• To borrow equity to renovate your primary residence.
• To borrow equity to pay down debts or cover a major expense.

If you have a second mortgage on your vacation home, you might choose a cash-out refinance instead of refinancing the second mortgage to consolidate the debt.

Deciding whether to do a cash-out refinance or consider a lower rate for your existing home equity loan or home equity line of credit (HELOC) requires a blended rate calculation.

A Rocket Mortgage Home Loan Expert can help you with the calculation, which involves taking the weighted average of your existing mortgage rate and your hypothetical second mortgage rate. This is compared to the rate you could get for a cash-out refinance. If the cash-out refi rate is lower, that option will save you more money. Our refinance calculator can help you decide which option is better for you.

You may have noticed that when you bought your second home, you ended up with a slightly higher mortgage rate than you’d get with a primary mortgage. Similarly, second-home refinance rates may be higher than those for a primary home.

Lenders typically view a second mortgage as riskier because homeowners are more likely to stop making payments on their second home rather than their primary home.

Refinancing a second home vs. a primary residence

Many of the steps for refinancing a secondary residence are the same as those for refinancing a primary residence, with minor differences. For example, you may need to provide your lender with more documentation than you'd need if you were refinancing a primary residence.

Here are some quick similarities and differences between refinancing a primary vs. a second home.

Can you refinance a second home that earns rental income?

Yes. To classify a rental as a second home, the IRS requires you to live in the property for more than either 14 days per year or 10% of the days during the year the home is rented at a fair rental, whichever is longer.

Consider consulting with a tax professional to learn more about how rental income is taxed.

Qualification requirements for refinancing a second home

How do you refinance a second home? Let’s look at some of the basic things you need to know.

Credit score

Your lender checked your credit score when you first bought your home, and it will check it again when you refinance.

Generally, the higher your credit score is, the lower your interest rate will be. Keep in mind that lenders set their own criteria, so check with them for specific requirements.

Loan-to-value (LTV) limits

LTV compares the amount you’re financing with the appraised value of your property. You'll probably need a LTV below 90%, meaning you'll have at least 10% equity in your home.

With a rate-and-term refinance for a second home, you can leverage up to 90% of the property value, meaning you'll need 10% equity. However, with a cash-out refinance for a second home, the maximum LTV is 75%, so you’d need 25% equity.

Lenders use LTV to determine your interest rate and how much you can borrow.

Debt-to-income (DTI) ratio

DTI shows how much of your income is required to pay your monthly debts. Lenders use it to measure your ability to manage monthly payments on your loan.

How would you calculate DTI? Let's say your monthly debt payments are $2,000 and your income is $6,000. You'd divide $2,000 by $6,000 and multiply by 100 to get a DTI of 33%. In most cases, an ideal DTI is under 43%. Lenders set their own criteria, so check with yours for their requirements.

You can reduce your DTI by paying down debts, boosting your income, and avoiding new credit or loans.

Cash reserves

Cash reserves are savings you can use if you lose income to pay housing-related expenses, including a mortgage. Reserves can include savings and checking accounts, as well as investment funds such as stocks, bonds, mutual funds, certificates of deposit, money market funds, and trust accounts.

Because a second home isn't your primary residence, lenders usually require at least 2 months of mortgage payments in reserve to ensure you can still make the payments in case of a financial setback.

For investment properties, lenders often require cash reserves of 6 months or longer.

Check with your lender to determine their guidelines.

Second-home refinance rates

Second-home mortgage rates are typically higher because lenders know you'll prioritize your primary mortgage if you fall on hard times. They know a second home may be more likely to fall into disrepair.

Second home mortgages are seen as inherently riskier investments, but that doesn't mean they aren't worth it to try to reduce your interest rate or lengthen your loan term. Note that lengthening your loan term will cause you to pay more in interest because you're stretching your payments over a longer period.

FAQ

Here are answers to common inquiries homeowners have when refinancing a second home.

What are the differences between refinancing a second home vs. a primary residence?

Interest rates are usually higher for second homes compared with primary residences. Lenders may require higher down payments, more or different documentation, and larger cash reserves. Check with your lender for specifics concerning your situation.

How does earning rental income influence my refinancing options?

Depending on lender policies, rental income could reduce your DTI. The additional income can offset the debt involved when you borrow or refinance. Prepare to document this income with bank statements and lease agreements.

Rocket Mortgage doesn’t accept rental income from vacation homes as a qualifying factor when refinancing that vacation home.

How can I secure the best rate for my second-home refinance?

Maintain a high credit score and keep your DTI low. Consider different types of lenders to compare interest rates and other factors, including loan terms.

The bottom line: Refinancing a second home comes with higher interest rates

Refinancing a second home lets you borrow the equity in your vacation property to pay for renovations or adjust your loan terms to save you money. Since lenders take more risk with these properties, you can expect higher interest rates and stricter cash reserve requirements.
