Since you are fresh out of Ch. 7 BK it will be hard to get conventional lending. Your best option is to get a land contract. With $30k down you have some leverage that will allow you qualify and possibly work terms in your favor. This will allow you to purchase right now when values are low and as banks begin to lend, you can refinance on your property at more desirable terms.
If you are looking in the Grand Rapids, MI area LandContractRealty.com has about 40 properties at any given time, so they would be able to help get you started in the right direction.
Hope this helps!
