When we started the rehab, it became apparent that he just did not have the time to devote to being over at the property working on it so some of the stuff that we initially planned on him doing, we had to move to having our contractor do.

CPA fees internalize many factors. 

I have heard that inspectors need a special certification to inspect that stuff.

Also, don't forget all the stuff you will need to get started, furniture, full kitchen, linens etc.

The general public needs a governing body to oversee this stuff to protect the public's interests.

I think $300 sounds unreasonable to me in moving expenses to move across the complex, unless they hired people to move their heavy stuff.

The fun stuff we run into after years of various remodels right?!?!

I've looked through the DIY ones like HudHomes and List Source but don't have a lot of time to a la carte stuff.  

Risk has to be met with a price reduction to offset risk.You'll have to but as is with no inspection and a price to match.Or the owner will need to evict and arrange to pay people to move all the stuff out.you could talk to the renter and offer cash for keys.

Look at everything that has sold, look at stuff on the market, start making your own comparisons, basically you want to know almost instantly if its a good deal or not (Of course the inspection will give you a better understanding) But from the outside, for the offer, you need to act quick, especially in this market for small multifamily.
