Mortgage Refinancing: Should You Refinance?

There is no universal threshold. The old rule of thumb about a one- or two-point drop ignores the two variables that actually decide it: your loan size and how long you will keep the loan. On a large balance, a small reduction can recover closing costs quickly; on a small balance, even a large reduction may not. Compare the monthly reduction against the closing costs and against how long you expect to stay.

It is the number of months of payment reduction needed to recover the cost of the refinance. Divide the closing costs by the monthly saving. If you expect to keep the loan comfortably beyond that point, the transaction has time to pay for itself; if not, it generally does not.

It can. Refinancing into a new 30-year term after several years of payments lowers the monthly figure partly by extending the payoff, which can increase total interest even at a lower rate. Refinancing into a term matching your remaining years avoids that, and refinancing into a shorter term accelerates payoff at a higher payment.

Sometimes, but check first whether you need to. On many conventional loans, mortgage insurance can be cancelled once the loan-to-value threshold is met, without a refinance and without closing costs. FHA loans are different: on most FHA loans originated since 2013, the annual mortgage insurance premium remains for the life of the loan, and refinancing to a conventional loan is the usual route to removing it.

A rate-and-term refinance replaces the existing balance and closing costs only. A cash-out refinance adds new borrowing on top and returns the difference to you at closing. Cash-out transactions are underwritten and priced differently, generally with more conservative loan-to-value limits.

There are costs on every refinance. What varies is who pays them and how. They can be paid at closing, financed into the loan balance, or offset through a lender credit funded by a higher rate. A no-closing-cost refinance is not free — the cost is moved into the rate or the balance.

It depends on the loan type and the transaction. Some programs impose seasoning requirements before a refinance is permitted, particularly for cash-out and for streamline options. Your loan officer can confirm what applies to your specific loan.

The credit inquiry and the new account have a modest, temporary effect. Mortgage inquiries within a short shopping window are generally treated as a single inquiry by common scoring models, so comparing several lenders in the same period is not penalised the way separate applications over months would be.
