If you took your mortgage when rates were near their October 2023 peak — brushing 8% — 2026 has put refinancing back on the table: the 30-year fixed has spent the year in the mid-6s, and February's brief dip to 5.98% showed how quickly a window can open. Just be clear-eyed about what you are signing up for. A refinance is a full mortgage application, with the same underwriting, appraisal, and paperwork gauntlet as the original loan. Whether it is worth doing at all is its own question — our guide to whether you should refinance in 2026 covers that. These four tips are about doing it well once you decide to move.

1. Check your credit — it is free now

The lender's first stop is your credit, so make it your first stop too. You can pull your reports from all three bureaus free every week at AnnualCreditReport.com — a permanent entitlement, no purchase required — and most card issuers and banks now show you a credit score free as well. The old advice to pay for a look at your own file is dead.

Read the reports for errors and dispute anything wrong before you apply, because your score is one of the biggest levers on the rate you will be offered — here is what lenders look for when setting your rate. If the score is soft, a few months of on-time payments and paid-down balances can be worth real money on a loan this size.

2. Know your home's value — and your equity

Most refinances require an appraisal, and the loan-to-value ratio it produces shapes everything: keep the new loan at or below 80% of the home's value and a conventional refinance gets done without private mortgage insurance. The good news is that years of rising values have done much of the work — the average homeowner was sitting on roughly $302,000 of equity by mid-2026 — so your ratio is probably far better than it was the day you bought.

If your equity is thinner or your income is stretched, do not assume you are stuck. The crisis-era HARP program ended back in 2018, but it has active 2026 successors for loans owned by Fannie Mae or Freddie Mac: Fannie's RefiNow and Freddie's Refi Possible. Both are aimed at borrowers earning no more than their area's median income, must deliver at least a 0.50% rate reduction, allow debt-to-income ratios up to 65%, and include a $500 credit toward the appraisal. Ask any lender — not just your current one — whether your loan qualifies.

3. Gather your documentation early

Refinance underwriting wants the same evidence a purchase loan does: recent pay stubs, tax returns, bank statements, and often statements for retirement or investment accounts. Your new lender will also need a payoff figure from your current servicer, so find out who to contact before crunch time.

The pattern is simple: the faster you hand over complete documents, the faster you close — and slow closings have a cost when rates are moving. The borrowers who caught February's sub-6% moment were, almost by definition, the ones with their files already assembled.

4. Know the costs going in

A refinance is not free. Between origination fees, title work, the appraisal, and the rest, closing costs typically run 2%–5% of the loan amount. Paying discount points to buy the rate down, or bringing cash to close to fix a loan-to-value problem (a "cash-in" refinance), adds to the tab by choice.

Whether those costs pay for themselves comes down to one division problem — costs divided by monthly savings — and we keep the worked math in finding your break-even point. Run it before you lock anything.

None of this makes refinancing painless. But a borrower with clean credit, a known equity position, a complete file, and a break-even number in hand has removed most of what makes it brutal.
