We are currently going through the process of an FHA 203k. We used an independent broker named Bobby Allison in Chattanooga, TN from American Home Mortgage: http://americanhomemtg.com/
There are 2 types of 203k's: the streamlined and full version. If your rehab estimate is more than $35k or you have to make structural changes to the property you must use the full verison which has more oversight from FHA inspectors and more paperwork. We are going the streamlined version.
The biggest hurdles that we have faced so far was getting the estimates from contractors and they must be licensed and insured. You must get 2 estimates. For the most part, contractors don't want to deal with the detailed bidding process or the hassle in paperwork.
All work that will be done must be in the rehab estimate even if you plan on doing the work yourself. The reason being is that for some reason you are not able to complete the work yourself, it must be covered in the budget. Also, any work that you complete yourself, you can not be compensated for and the project must still be oversaw by a licensed contractor.
And these types of loans take a while to complete. 60 days is probably the soonest you can expect to close if everything goes perfect. We are at 4 months right now, but should close within the week. We had some other issues arise like title issues (having to get survey done) that has delayed closing. Our original closing date was April 29. We went under contract on February 6th, I think.
Here's some guidelines from the streamlined version/bidchecklist of the 203k. Follow the link:
