Current homeowners who sign a contract to buy a home on or before April 30 get a dollar-for-dollar reduction on their taxes of 10% of the purchase price of the home, up to a maximum of $6,500 (first-time buyers can get up to $8,000).

But according to the National Association of Realtors, buyers spend about 12 weeks home shopping before making an offer, so if you haven’t already started looking, you may be pressed to meet the deadline.

Plus, to qualify for the full credit, your household income must be under $225,000 if you’re married and less than $125,000 if you’re single; repeat buyers must have lived in the home they are selling for five of the past eight years.

The good news: Once you’ve signed the contract, you have until June 30 to close the deal.
