Congrats on pulling the trigger on this.

I guess the purpose for this is to help fund community improvements and maintenance though it's a bit unusual since HOA fees and property taxes typically cover these.

Because we don't refund application fees. 

Typically, HUD charges a daily fee for extensions, which varies depending on the property type and the number of extensions requested.To request an extension, contact your HUD representative or the Asset Manager handling the sale.

I never cared what they are making as the assignment fee, as long as I knew the numbers worked on my end.As for a purchase & rehab lender that will finance up to 100% of the wholesaler's assignment fee - I can introduce you to one that finances that and also 100% of the purchase & rehab up to 65-75% of the ARV.As a lender I sometimes receive off-market properties from wholesalers and other sources and share them to our borrowers if they fit what they are seeking.

Is there a no win / no fee type of service I should be searching for?   

In Cleveland, it is industry standard to pay a 10% property management fee.

Expect to allocate less time  towards management functions if self-performed or more favorable management fee structures if 3rd party management companies are utilized (which ties back to #1, as well).

So, the first question they usually ask a PMC is about fees - instead of asking about services and HOW those services are executed.EXAMPLE: PMC states they will handle tenant screening – what does that specifically mean?

Quote from @Alex Scattareggia: Is the problem that the property wont be profitable with the 20% management fee taken out?
