What to have in place, and what to check, before you apply to refinance an existing mortgage. Work through each part below with your own numbers and documents, and keep notes as you go.
Pull your current loan details
Find your latest mortgage statement and note the principal balance, interest rate, remaining term, escrow amount and whether you pay mortgage insurance. Check your original note or Closing Disclosure for any prepayment penalty. These details are the baseline every refinance offer needs to beat.
Define the goal in one sentence
Write down what the refinance is meant to do: lower the monthly payment, shorten the term, remove mortgage insurance, switch from an adjustable to a fixed rate, or take cash out. Each goal leads to a different product and a different way of measuring success, so lenders can quote more precisely when you are clear.

Estimate your home's value and equity
Look at recent sales of similar homes and your county assessor's records to form a rough value range. Equity affects which programs are available and whether mortgage insurance applies. The lender's appraisal or valuation will set the official figure, so treat your estimate as a planning range only.
Plan for timing and costs
Refinances usually involve closing costs similar to a purchase, including title, appraisal and lender fees. Ask how long the process is taking, whether the lock covers it, and whether your first new payment date means you will skip a month. Skipping a payment is not free money; interest is still owed.
