How Interest Rates Affect What You Can Afford

When you're buying a home, it's easy to focus on the purchase price. But if you're financing, the interest rate on your mortgage can have a big impact on what you can comfortably afford.

Even a small change in rates can change your monthly payment—and sometimes your buying power.

It's About the Monthly Payment

Most buyers have a monthly housing budget they're comfortable with. That payment includes more than just principal and interest. Depending on the property, you may also have taxes, insurance, flood and wind coverage, and HOA or condominium fees.

Here in the Florida Keys, those additional expenses can be significant, which makes understanding the entire monthly payment especially important.

Higher Rates Can Reduce Buying Power

When interest rates increase, the monthly payment on the same loan amount increases. That means a home that comfortably fits your budget at one interest rate may become less affordable at a higher rate.

The opposite is also true. When rates come down, buyers may be able to afford a higher-priced property while keeping a similar monthly payment.

Don't Shop Based on Price Alone

I've seen buyers say, “I'm approved up to $800,000,” and immediately start looking at $800,000 homes.

But being approved for a certain amount doesn't necessarily mean that's what you should spend.

Before you begin looking, ask your lender to show you estimated monthly payments at several different purchase prices. Then decide which payment you are comfortable with.

Remember the Other Costs

This is particularly important when buying in the Florida Keys. Insurance, property taxes, flood coverage and HOA or condominium fees can change considerably from one property to another.

Two homes with the same purchase price can have very different monthly ownership costs.

Rates Can Change During Your Search

Interest rates don't stay in one place forever. If you've been looking for several months, don't assume the numbers your lender gave you at the beginning are still accurate.

Checking in with your lender before making an offer can help prevent surprises.

Focus on What Works for You

Interest rates are important, but they're only one part of the decision. Trying to perfectly time rates—or the real estate market—is difficult.

A better approach is to understand your numbers, consider the total cost of owning the property and choose a monthly payment that you're comfortable with.

At the end of the day, the question isn't simply, “How much house can I buy?” It's “How much house can I comfortably afford?” There's a big difference between the two.
