Different states have different rules about these things so Florida Mortgages are different from California Mortgages for example.
However, it's always true that mortgage refinancing (sometimes known as mortgage refinance) can help you in your pursuit of your financial goals.
It could be that you can refinance upon better terms, thus cutting your monthly payments: this is really something for nothing. You might also want to extend the term of the loan. This will cut the monthly payment while making you pay it for longer. Or, you might simply want to take out some of the equity you have to spend on something else.
Worth looking into: I've just done it myself, using the money to buy a second home.
