Answer: -It wouldn't hurt you to check out a couple of different lenders just in case. I think it's possible to get lower than that. Keep looking. -That's pretty good. It is somewhat negotiable but it depends on who you got the mortgage through. Always get a second opinion if you aren't sure of the first. -You must have something else going on.... Manufactured Home?, Acreage?, No Income Verification?.....There are a lot of things that go into rate. The 800 credit score just allows for a approval of a loan, and not necessarily a "fantastic" rate. Also, the loan to value has a great deal to do with it. You should have 20% down on a purchase, in order to qualify for the best rate. -Your income and the amount of downpayment (percent of the home value that you intend to finance) can also play into the mortgage rate. Some lenders sell 'points' where you pay up-front money to buy a lower interest rate. -Mortgage rates differ a lot and are based on your credit rating and the value of the home. Before approving your loan, your lender will scrutinize your credit history. There are two types of mortgages according to the type of rate: fixed or adjustable. Consult a mortgage broker or contact the lender directly asking for quotes. This lets you decide between both the varieties of mortgages.
