There are plenty of programs out there that allow you to get in to a home for 0 down. With FHA loans becoming more prominent, lenders are looking for ways to utilize these loans. With an FHA loan you will pay Private Mortgage Insurance (PMI) which can be very costly. You will pay PMI until your Loan To Value (LTV) is at 78%. We can make this real simple by saying that your home is worth (value) $100, your loan can only be for no more than $78 to be rid of PMI.
Depending on what you are looking at purchasing and the amount that you are planning on spending there are other loans available. If you are looking to purchase for less than 500K and you have a combined income of less than $104K you can look into the ACORN program offered by BofA.
I would be glad to help you find the right lender, who can help you make the proper decisions for your situation.
I wish the best on the search for your home and loan program!
