With a credit score below 585, you will need to put at least 10-20% as a down payment on the property. You will not likely be approved for 100% financing at this point.

If you have a credit score of between 585-599, you will probably need around a 5% down payment in order to get an approval for a home mortgage loan. You will still need to get your approval from a subprime mortgage lender. You will need to use a lender who specializes in loans for people with "less than perfect credit" or situations that make it difficult for a person to get financing for their home.

If you have a credit score of 600 - 620, you will probably be able to get an approval for 100% financing. You will also, in this situation, still need to use a subprime lender.

With a credit score of 620 or higher, you may be able to not only qualify for 100% financing, but be able to get a lower rate of only 1 - 2 percentage points above the prime rate.

If you have a recent bankruptcy or foreclosure, these estimates should still be accurate within 2 years after bankruptcy, repossession or foreclosure. After 2 years, it becomes easier to get approved for a mortgage loan, because more lenders will look at financing you after 2 years, whereas many lenders will not even consider your application until 2 years from the time of bankruptcy discharge or a foreclosure. After a 3 year mark from the time of bankruptcy or foreclosure, it becomes even easier to get an approval, in that many more lenders will consider your application after 3 years.
