You should say goodbye to PMI. You may not notice it in the crush of your monthly mortgage statement, but many Americans pay for a line item called PMI. PMI stands for "personal mortgage insurance," and lenders impose it on customers who have less than twenty percent equity in their homes.If you took advantage of a low-money-down offer, the PMI will protect the bank if you go bankrupt. Once your equity has risen above twenty percent, call your lender to cancel the PMI - you no longer need it. Y.
