I would also check your RE laws in MD. Sounds like you might be close to an ethics violation. So, you'd be getting paid the commission and an assignment fee? The LLR might have something to say about that. Adding an additional fee in there (your assignment fee) would necessitate a bigger spread on the deal, which would compromise your buyer's position and offer. Just CYA for sure.
As for HUD homes, there is no inspection period contingency for investors, so if the numbers are close, I always go out and see the condition for myself. Not all HUD homes are move in ready. In fact, in my area, most are not. Also, the escrowed amount for repairs is nice, but on a cash deal, that goes away, so remember to negotiate a lower offer in a cash deal when repair escrows are offered.
Even then, when your bid is accepted in an O/O deal, you (the buyer, more specifically) is responsible for all costs to dewinterize/rewinterize, and turn on utilities for inspections. That could end up costing a significant amount up front and out of pocket before closing.
Good luck.
