Since lenders are not going to exercise restraint with regard to the mortgage loan you can qualify for, you will need to exercise that kind of restraint for yourself instead.

In order to be as prepared as possible for the closing, get an estimate from your lender well in advance as to what your total closing costs should be. Then set this money aside and make sure that it is not used for anything before the actual close of the deal.
