Hello, buying a house with no money down is the reason why most people today are losing their homes. The fact is when you don't pay down on the mortgage you get a high interest rate and your mortgage payments are very high. Also, if you don't have any money to put down on a home you may not be ready to buy and maintain a home.
Make sure when the mortgage broker gives you your monthly cost that you can honestly say you can afford it and still have a comfortable financial life. Also, make sure you get a fixed rate not an adjustable rate mortgage.
