There are deals but they are few and far between. I got one from a wholesaler today but it required cash or hard money. As a first time investor I wouldn't recommend you go that route. It's pretty hard right now to cash flow on a MFR when your in one of the units because purchase prices have sky rocketed.
203k loans are a pain in the butt in a hot market. Three reasons.
1-It's and FHA loan and most sellers are worried about them because they don't want to do any repairs and you have to explain that it's a 203k not a traditional one. Some sellers get it others don't.
2-You have to use a contractors who are approved by the bank or lender do the repairs meaning you'll spend more money on the repairs. You can't do them yourself.
3-The under contract time is much longer than usual because of all the bids you have to get.
I'm not a fan, but I am willing to have someone tell me I'm wrong if they have had a better experience.
Your best bet is to buy a property from HUD or a Bank during their owner occupant time and not compete with investors who have deep pockets. I haven't seen one in recent months though. I think the MFR is out of control.
