Step downs in living and formal room beautiful 1970 wood on interior walls, messed up kitchen.  

It may however influence what bid amount the foreclosing lender will allow the property to go for at auction though.

Areas of the building need power washing.On the interior, I have walked vacant units and on the naked eye they looked in ok shape.

There is pretty significant interior damage, but "the bones" of the house are still good.

But now you have tech so well entrenched.. you have Chinese capital by the billions that has paid cash for prime BA real estate along with many other nationalities.. any area can suffer a correction.. but unless there is a Major Earth quake or some other outside influence . 

We inspected the interior of every unit, and I must say, I was impressed.

There are people around us that can be a negative influence.  

B can go either way as we know it can start at B and end up at C if some outside influences happen..  

What are some strategies and ideas about how a real estate investor and an interior architect work together?

That 50% rule is pretty much for investors who can't really analyze a property disregarding things like appreciation, taxes, ability to change use, influence neighborhood markets, principal reduction and better management techniques lowering you actual expenses over time.
