Try finding a really good broker. One that can be trusted... But is still willing to go the extra mile on hunting a way for you. It's tough right now. But someone good with the motivation to secure a loan may be able to find a way. Especially when they have a reason to.
Example: you'll need a good RE Agent to look at houses once you know your range. It's best to find out first(your range) and get pre-qualified. But a really good agent will have connections to an excellent broker for various loans.
The relationship some of these people have in selling.. is often motivation enough to find a way to qualify you. Especially if your a first time buyer. It may take some time. But have patience. Try looking some agents/Brokers over.
