Mortgage Refinance: A Plain-Language Guide

What does refinancing a mortgage mean?

Refinancing swaps out the home loan a borrower already has for a new one that usually carries different terms. People might look into it to move to a different rate, lengthen or shorten the loan term, or change the way the loan is structured and repaid. When the new loan closes, it settles the old balance, and the borrower then repays on the new terms. None of this happens automatically — each lender judges a borrower by its own standards, so the rate, term, and overall cost can land in different places from one lender to the next. Setting offers from a network of lenders next to one another can give a borrower a sharper sense of how those terms vary before deciding whether to go ahead.

Refinance products you'll often see

Two routes tend to surface when borrowers look over refinance products. With a rate-and-term refinance, the old loan gives way to a new one that changes the interest rate, the length of the term, or both, while leaving the principal balance largely as it was. Whether the term gets shorter or longer comes down to what the borrower wants and what the lender puts on the table. A debt-consolidation refinance can fold higher-rate balances — credit cards or other loans, for instance — into a fresh mortgage tied to the home; since the home stands as collateral here, it's worth reading the lender's terms closely. The labels and the way these products are built differ by lender, and no single lender carries them all. For a deeper look at borrowing backed by the home, Learn More about home equity products.

Factors lenders tend to weigh

Because each lender in the network reaches its own credit decision, the things that carry weight aren't the same everywhere. As a rule of thumb, a lender will look at the borrower's credit picture — credit history and what's currently owed — along with income and how steady employment has been, the home's estimated value set against how much equity the borrower holds, and the size and length of the loan being requested. The kind of property and where it sits may enter into it too. No single one of these settles an offer on its own; lenders pull several inputs together when they decide. Comparing offers can show how differently lenders treat the same factors.

Comparing one offer against another

Laying lender offers next to each other brings a handful of elements into focus. The interest rate is only part of the story; the points and fees riding alongside it shape what the loan really costs. Term length pulls on both the monthly payment and the interest a borrower pays across the whole loan. Closing costs aren't uniform from lender to lender, and neither are prepayment rules — some loans tack on a penalty for paying early, others leave that out. The APR gathers many of these costs into one number that's handy for lining offers up, though the pieces feeding into it still deserve a look.

Points worth weighing

Refinancing comes with trade-offs, and a few of them are worth sitting with before making a call. Closing costs usually get paid at the outset or folded into the new loan, which means a smaller monthly payment won't automatically add up to savings overall. How long someone expects to stay put in the home bears on whether those closing costs can be earned back over time. And the total interest paid across the loan's life can move in a different direction than the monthly payment does.

Glossary

• APR — annual percentage rate; folds the interest rate together with certain fees to state the loan's yearly cost.
• Points — charges paid to a lender at the start, frequently used to shift the rate the loan carries.
• Closing costs — the fees settled at closing, covering things like title, appraisal, and origination.
• LTV — loan-to-value ratio; the loan amount stated as a portion of what the home is worth.

Refinance products aren't all alike, and which comparison makes sense hinges on a borrower's own circumstances. Putting offers from a network of lenders side by side can help a borrower see how the terms stack up — with no obligation to proceed with any lender. Since each lender decides on credit by its own measures, the result reflects those separate reviews. SmartFin USA neither originates loans nor makes credit decisions; what it aims to do is make that side-by-side look simpler.
