Another popular tactic, which can be used in a wider range of programs, is to borrow from your 401K program. If you have a 401K program with your employer, you can withdraw without a penalty for your down payment and pay it back over a specified period. There are some drawbacks, the payment will be used in qualifying and your 401K account will not continue to grow as fast. Even with these drawbacks, it is often a smart move if this is your only option.
