Hi Mark -
How long ago was the auto repossession? If it was more than seven years ago, it should have dropped off your credit report by now. If more than three years ago, the effect on your credit would be somewhat diminished compared to what it would be less than one year after the repossession.
But the key is what your credit score is. If your score is 620 or higher, you should be able to qualify for a FHA mortgage, sometimes with a score as low as 580. With a higher score, you might consider a conventional loan. Many credit card companies and banks now provide your credit score for free as part of your monthly statement or by logging into your account online.
Otherwise, you can order your score directly from the Fair Issac Company at www.MyFico.com, though there's a $20 fee for each score you order. Note this is different from your credit reports, which are available free of charge from each of the three credit reporting agencies once a year.
If you know your score, you can use the free quote form at the top of our home page, https://www.mortgageloan.com/ to find out if you'd qualify and get personalized rate quotes from up to three lenders. Good luck!
