Why would you want to keep it "behind the walls"?

By definition, these type of loans are not the same quality as what is traded on wall street. 

they said around 90% of market value.I tried to get them to understand that this property needs a LOT of work, almost a full gut, some holes in walls (small) old carpet needs to be ripped up, i mean like the works on this thing, you can prob get away with touching up the kitchen since its real hardwood and the bathrooms as well but this prop needs at least 80k.Found out owner actually owes 140k on property, and zillow is zestimating it to be 127k.

Water is now leaking through the ceiling into my tenant's unit, and it's worsening with every rain also the neighboring unit has sever water damage (like a pool inside and it is owned by the HoA) and water from it leaking very dirty water from the shared wall to mine.

I sold the other Class C while it was vacant - I saw the writing on the wall so decided to cut my losses. 

Cheap materials, thin walls, the LVP was peeling already not to mention the transient individuals in the parking lot. 

Are you aware that over 80% of Wall Street / Stock market companies DONT last that long?     

Darien Pass/Panama-  There already is a couple hundred miles of JUNGLE wall there. 

They are far more common now and harder to find models without but:1) these add cost to the purchase price2) they don't bring a lot of value3) they can leak or detach and damage the propertyI own around 50 doors and I cap off the line at the wall or in the basement with a valve and a cap so the potential for leaks is 0.00001% :-) 

Expect to remodel kitchen and baths and put new floors down, paint, knock down a wall to open the floor plan.
