I suppose it is not too bad in class A areas and A to B buildings (hundreds of units) as income and class of tenant tends to be better.Everyone can have the so called high yield and high headache residential lower income tenants.

My question: If I purchase this duplex all cash, will I be able to pick up a mortgage with delayed financing? 

As a realtor, I go on probably 30 inspections per year for other people's properties, so I have picked up a lot of building knowledge that way too. 

So it’s a waste if you don’t have the tenants picked out and moved in the 30 days. 

Or can you find a realtor that works with investors and pick their brain?

My complex was D class when I bought it and $200k later it is solid C class.

For example, one LLC for every $5 million of investments (that number was picked arbitrarily). 

Converted hospital to apartment building years ago Owner pays utilities and you can't separateIt's in a class B-C area but not sure how I feel about most of the building being on government assistance.

Yea $75k in Cleveland you are in B-Class suburbs.

I think in some states you are required to provide appropriate accommodation if the apartment is unlivable, but unless she was in a Class A apartment, Marriott seems like a luxury.
