San Diego area, conforming non-jumbo loan. Went from 3.75 to 2.75, no points, no fees, etc. Did extend the term to 30yrs from the 22yrs that were remaining. Roughly a $600 per month cash flow savings.
Other options at the time were 2.75, no points etc. same monthly payment with a 2yr reduction on the term to 20yrs or 25yrs with cash out, roughly the same monthly payment.
I don’t plan on living in this house for more than 15 years, when I no longer need access to the public school district for my kids. But... $600/month over 15yrs is a savings of $108,000 in cash flow over that period. I’m looking at that as a down payment on the next home down the road (plus investment income on that cash saved) and will turn the current property into a rental. I doubt rates will be anywhere near this level by then and will use the added rental income to offset any future home purchase increases in P&I payments while doubling my equity growth in the process with the next property.
