We all know that to qualify for the first time home buyers credit there must be an accepted offer by April 30th. But if buyers wait until the 30th they might still miss out on the credit.
There are a lot of things that need to happen before the offer is really "accepted". All the contingencies must be met and if there are issues found they need to be worked out before the 30th if the buyer wants to make an offer on another house.
For example, let's say that an offer is accepted by April 30th and the lender orders an appraisal the first week in May. If the appraiser finds issues with the house that prevents the loan from being accepted, the buyer has only one choice, fix the problems or lose the credit. It is too late to find another property.
If all of the deadlines are worked out, it is almost already too late to be certain that an offer will go to close and the buyer will be able to claim the 1st time home buyer credit. Don't let the April 30th date lull you to sleep.
