Good afternoon doodlebugray,
Most Lenders today require a minimum credit score of 640. Your score indicates there are some serious credit issues on your credit report. Please take the advice of a mortgage professional with 23 years experience: take the time to put your financial house in order before you undertake the huge responsibility of paying a mortgage.
First, settle any outstanding debt. If you owe money on collection accounts, charge-offs and/or judgments, make payment arrangements and get these accounts paid promptly.
Next, begin rebuilding your credit. If you have current accounts with good payment histories, or even some previous late-payment-blemishes, make sure you continue to pay those accounts on time. If you do not have any existing credit accounts then you'll need to establish several in order to create a viable credit history.
I have found that CONSUMER ACTION is an excellent resource for objective advice on all things credit related. You'll find free and sincere advice on everything from settling collection accounts to rebuilding credit to building credit from scratch on their website.
Beware of anyone offering to "repair" your credit! The Federal Trade Commission issued a stern warning last year that such offers are scams.
The best way to buy a home is to have a decent credit history combined with sufficient Income and Assets for a home purchase.
