The only thing in our agreement about marking up bills is that they may add a surcharge on larger projects (several thousand dollars) as a coordination fee.

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.

(Taxes, prepaids, attorney fee, origination fee etc) So let’s assume your acquisition cost is $227500.Cash flow is income - expenses.Expenses are PITI, vacancy (5% of rents), capex (5% of rents), repairs (5% of rents) and property management (10%) of rents, plus lawn maintenance, HOA fees etc.

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?

@Judy Jacobs, consider fees and exchange rates to maximize the amount received.

Soft cost, carry cost, offsite and fees/.2 = 10,000,000 Total Build Cost 40 pads= 250k per pad Cost [250k/$150 per square ft = 1666 sqft per unit] 250k per pad x 20% = 50k for land ready to build. 

Or you can keep making mistakes that cost you THOUSANDS of dollars to save a hundred a month in PMC fees.
