Mold remediation is addressing the moisture problem, paint over any discolored areas with Killz and put fresh paint in your color over the encapsulant.

I would also recommend that they have sufficient 'skin in the game' IE additional down payment above and beyond just having lived there a while. 

ZERO skin in the game. 

It might be cracking and heaving inward which might require both dealing with exterior ground moisture and also stabilizing the foundation from the inside with one of a few options.

Double-tapped breakers, all dishwashers did not function at all, multiple sinks and faucets actively leaked, Improperly installed flooring that had buckled, very high humidity in one units was causing moisture damage, furnaces full of drywall dust, radon systems that were not air-tight in the sump pit, and the list goes on and on.I listed just a few of what would ultimately be the longest repair request I've drafted in my career.  

Again, other might feel differently here.b) Skin in the game: as a conservative investor, I understand that the dirty secret of industries that the waterfall compensation is in the line with me and incentivizes sponsors to take more risk.

The post wicks moisture and gets soft/rotten at the bottom and sinks allowing the floor above to sink a little.

Why every renter hates living in big multifamilies and dealing with bullying property managers with no skin in the game.

I’d love to hear from people that have had skin in the game for a while.

Most will require some skin in the game and they lend on the property and your experience, not your jobs.
