when the economy gets bad and people get desperate, some people have no scruples and will try to scam any way they can.
If you are trying to get a mortgage, beware of online scams who are trying to just get your information so they can steal your identity and ruin your credit and your life. Also beware of brokers or lenders who tell you one rate and then give you another (higher rate). Be sure you do business with a "Realtor" or someone else you know and trust. Realtor's have specific ethics they have to abide by.
Some people are already finding ways to scam the tax credit, and it makes it tougher for those of us who are trying to complete honest business transactions. keep heart there are good, honest, people who will help you get the mortgage you need.
