Here is a summary of the changes:

First-time buyers who have not had interest in a principal residence for three years are still eligible, and the maximum amount remains the same; $8000 for married couples, $4000 for those filing separately.

Current homeowners who have consecutively maintained the home they want to sell as their primary residence for five of the last eight years are also eligible. However, the maximum amount for those homeowners is lower; $6500 for married couples and $3200 for those filing separately.

The tax credit may not be used to purchase a home for more than $800,000. All buyers who want to get the credit must include documentation of the purchase on their tax returns.

The income limits for both tax credits have been raised to $125,000 for single buyers and $225,000 for married couples.

Thats it in general terms – and in a nutshell. If you have specific questions, please contact me.
