I'm in a 203k loan now, and about a months a half to finish the project. The 6 months timeline that was mentioned here can be extended, which I did with mine. There is lots of paperwork in the beginning, but after that it should be all good.
The big downside is to have to pay for everything upfront, and than have the bank pay you back. @Bill Rich if you have a way that I don't have to do that, I would like to hear about it for sure.
Also my 203k loan only allowed me to have 4 draws, which means you have to make sure you calculate correctly the $$ you have saved to cover the expenses before the draw. Basically if you need $100K you will have 4 draws of $25k lets say. Basically have $25k to pay upfront, to than get that back and move to the next phase.
There is also a fee for every draw, which should be built in to your loan.
HUD consultants, if you get a good one, you are good, if you don't that can make your 203k loan a nightmare.
Also be extremely specific and go over all numbers of the project with the HUD consultant, and the contractor. The HUD consultant will do their estimation of the work, and you need the contractor to do the same for you.
As an example my estimation did not include the dumpsters, and I did not verify, I ended up using 8 dumpsters!!! Out of pocket expense : (
I believe that is it for now. I would do it again now that I learned a ton with my first one. As it was said before make sure you have a company doing your loan who has done at least 100+ of these types of deals to help you navigate it properly.
Good luck.
