As for the tax credit, it's quite simple: the maximum amount is $750. The purchase of a home, however, involves many other costs that all crop up at the same time. We felt that the federal government could help to improve the situation at that point by increasing the tax credit. We suggest that it could go to $3,000, $4,000 or $5,000. This would really help people in situations where they need help the most.
