I’m factoring about $.50 per foot of interior floor space which equals $616.

You have to consider paint(exterior and interior) hot water heater, minor kitchen remodel, bathroom remodel, gutters, etc.

Title report, finding photos of interior, recently pulled permits, etc. 

And how does the interior look such as cabinets, floors, countertops.

Also, while you may not purchase a co-insured policy, most all policies have an internal co-insurance clause, requiring you to carry proper coverage amounts, or be penalized at the "option" of the carrier.

We are rehabbing a 2 bed/1bath condo in Jersey City, NJ and we're currently interviewing interior designers for the project.

.- Internal Rate of return of ~15% and cap rate of 5.5%.

New siding(added immediate curb appeal), removed old popcorn ceiling, re mudded walls, painted interior, cleaned, cleaned and then cleaned some more, added front deck, landscaped front & backyard, What was the outcome?

Typically they are high net worth individuals or groups (sometimes international) willing to buy something all cash and accept a minimal COC return for nice building w/ little maintenance etc.

I like to concentrate on the interior items to make the place functional but make a list of all the exterior items that need attention as well.
