Payments and rates vary based on borrower’s credit score, actual closing costs and other variables. Check with your loan originator for your mortgage loan interest rate. The decision to refinance a home mortgage can involve many factors. You might want to take cash out of your home at when you refinance to use for other purposes. But the most common purpose is to obtain a lower interest rate and lower monthly payments. In the latter case, the decision to refinance should be based on lowering the overall mortgage costs and breaking even on the refinance in a reasonable period of time.
