My first home was a 203K about five years ago. Mine was pretty nightmarish. Best piece of advice I can give you is thoroughly screen everybody who’s going to work for you as well as you can. If you can’t find much info on them, then keep it moving. I honestly dont recall selecting the HUD consultant. I think I was pretty much given a name via the bank and hired him. My total rehab was $53K w/ 10% contingency. This was for pretty much a full rehab. But really too lean of a budget in hindsight, but the low number made me feel good at the time. I never got a home inspection because my realtor referred to the HUD consultant as an inspector and said he had done an inspection and asked if wanted to have another one done. So I was kinda misled and it seemed redundant to me. But obviously get a home inspection. The consultant’s there to draw up a budget, not so much perform an inspection. My first contractor did the juicy/profitable larger items in the scope of work and then stopped. I don’t know if it still exists, but there’s a 10% holdback on all the payments until the end of the project. I argued with the bank that he wasn’t due his holdback because he didn’t complete the project. I finally ended up paying him the holdback too, because I needed to move on and hire somebody else because there used to be a 6 month deadline to get it done. Second contractor wasn’t much better. I paid for a good amount of stuff out of pocket, maybe $10-15K. Sold the house three years later made maybe $35-40K overall after everything but I could’ve made a lot more. But yes you can fire your contractor. And they’re going to come into the job expecting to use the entire budget and contingency, so yeah any leftovers maybe applied towards principal, but anticipate there being any. Also, the money can move around from item to item, not sure if you were aware. And as previously suggested, get as detailed a SoW as you can, so everyone’s on the same page and don’t take any crap like I did. ;) But after all is said and done,I’d do it again.
