Refinancing your home. We have the option to refinance from a 30 yr.Refinancing your home. We have the option to refinance from a 30 yr. at 4. 125% to 15 yr at 3. 175% that would raise our payment around $168/mo. It would take it from 15% to 18% of our take home. Closing costs are around $3, 000. Problem. We aren’t sure we will be staying in our house 3-10 years. We are already outgrowing it but not ready or in a position to move yet. We’d have over half our payment going to principal and interest plus lose PMI if we refinanced BUT it would take away that extra money to throw at our car (only debt). Anyone been in this situation or have advice? We’re still not sure which way we’ll go but leaning towards not refinancing.
