While the economy continues to show signs of improvement and many housing markets are beginning to heat up, scores of would-be buyers are still waiting on the sidelines for further positive housing trends. But for first-time buyers, time is running short on the federal government's $8,000 tax credit.

Though the official expiration date of the credit is December 1, in reality on-the-fence buyers will need to make a decision one way or the other fairly soon. The reason: in order to qualify for the credit, the home purchase must close by December 1st. Merely having loan approval, an accepted offer or a signed contract won't be enough to qualify for the Housing and Economic Recovery Act.

Decision-Making Timeline - While each transaction is unique, closing a real estate deal is no speedy matter. On average, closing takes place 45 to 60 days after the date that the contract is signed. In order to meet the December 1st deadline, this would mean having a signing date in late September or early October. Those who consider the tax credit an important incentive but are still unsure about entering the market will need to make a decision one way or another before many more summer days pass.

To have any chance at finding a home and having an offer accepted by early October, buyers will want to wade into the home buying process right away. The immediate steps include making a final list of desired home attributes, scouting favorite neighborhoods and areas, starting the mortgage pre-approval process and beginning the home search process online.
