The buyers need (not request) a full 5%-6% seller assist and become complete menaces and eat into your margins with lengthy repair addendums following inspections. 

They judge one building a duplex, and the other two townhouses, by visual inspection.

When you purchased the current property you should have expected many of your repairs if you performed an inspection.

I am an actual owner with 100+ units in the city of Cleveland and the cities around it and put together a rolodex of references for services like property management, inspections, contractors etc. if you want it. 

Lauderdale, FL•North Palm Beach, FL•Plantation, FL•Pompano Beach, FLThese acquisitions were done creatively, assuming the existing loans via subject-to deals without inspections.

One approach we've taken is implementing a move-in and move-out inspection (with photos) to limit wear and tear.

Nobody is living in the unit, the city came out to inspect the unit, nobody was there to let them in (it failed because of this).

My son did this for his first home and, other than paying for some lender fees and his home inspection up front, he only paid $11 at closing.
