Rate-and-term refinancing modifies interest rate or loan duration without changing principal. Cash-out refinancing borrows against home equity, taking cash out and increasing total loan balance.
Lenders do not waive closing costs; they either roll the costs into the principal balance or charge a slightly higher interest rate to cover the fees with lender credits.
Yes, if you have already paid 5-10 years on an existing mortgage, resetting the clock to a new 30-year term can increase total lifetime interest paid despite lower monthly installments.
Refinancing from a 30-year to a 15-year mortgage secures significantly lower interest rates and saves hundreds of thousands in lifetime interest while building rapid equity.
Shop around for independent title insurance and closing agents; title fees can vary by $1,000+ between competing closing companies.
Paying closing costs out of pocket prevents paying interest on loan origination fees over the next 15 to 30 years.
FHA loans require mortgage insurance premiums (MIP) for the life of the loan; refinancing into a conventional mortgage once you reach 20% equity eliminates MIP permanently.
