They rent well the value dynamics are different thean dry front properties of course and the factors that @Wayne Brooks mention are important. 

Account Closed   have not heard that one.. the poor Chinese they are blamed for everything .. first dry wall ... then faulty parts now they are nuking the public with their radio active granite  LOL... not sure how you can have radio active granite as its stone.I understand dry wall and chemicals in the flooring like lumber liquidators but I got to think granite is OK.. but there is cheap granite from India as well. those are probably laced with curry

The amount you need to wash off the panels depends a lot on the location, if you live somewhere dry and dusty, they'll need to be washed off pretty regularly, but if it rains and snows where you are that will get off the dirt, except in those really dry and dusty climates, it's not generally that big of an issue.

Other less expensive improvements would be adding credit card readers and in-bay drying systems.Keep us posted and Good Luck!

But if the work is mostly putting up dry wall, it may not be that expensive. 

The reason I am curious to find out the rehab cost per Sq ft is to come up with a decent enough guesstimate when analyzing properties.Assuming the property needs New Roof, HVAC, Carpets , Some dry wall, paint, Kitchen remodel.. etc.

I was starting to feel like I was crazy for wanting to buy something upstate--it seemed like most were starting to look elsewhere so I was wondering if the money/bookings were drying up here.

Are the 2-4 family properties plentiful, or will you be sitting on dry powder for a long time trying to find deals?  

They sell hard with their "we're here to protect the passives" talk, and then leave you high and dry if you get screwed over by one of their "leads".I'd never join again, knowing what I know about them now.

Update as of 4/16/2021: The tenant left a lot of flooring and dry wall damages.
