You are welcome - yes if it sold (legally was no longer yours) in January 2009, and it wasn't due to extenuating circumstances, then you'd have to wait until the 3-year anniversary, but really I'd recommend you wait until February of 2012 because FHA's automated underwriting system can't determine if a foreclosure was on January 1st or January 30th, it just thinks it was sometime in January, and so to get a favorable decision from the automated underwriting system you'd want to wait to have your credit checked until February 1st - you'll get easier underwriting treatment at that point.
However, if it was due to extenuating circumstances, and you have the 12 months of re-established credit and the no new delinquencies since, then you could be eligible for an FHA mortgage right now, but under the tougher underwriting guidelines (lower debt ratio limits, verification of rental history if you've been renting since, would be good to have some reserves still in the bank after closing, etc.).
If you are VA eligible (a Veteran or an unmarried widowed spouse of a Veteran), then VA loans just require 2 years from foreclosure in any situation. Obviously not everyone is eligible for a VA loan.
