I work with lenders that do FHA 203k all the time. Just make sure that the lender you choose actually does 203k, and does them frequently. Not someone who has them available. I may even ask how many they have done in the last 6 to 12 months (don't expect a VERY high number, as they are not all THAT common, but make sure they have closed several recently). I do a lot of work in the Salt Lake and Utah Counties, and have heard of Justin Coleman. Everything I hear is great. Maybe give him a call and see what you think.
Also BEFORE you get out of your due diligence period in the purchase contract make sure you have the loan fully approved. FHA 203k have certain items they can cover, especially if you are doing a streamline. Just don't lock yourself into a purchase, and then figure out that the loan won't work...
