Is it finished space with heating/cooling and normal ceiling height? 

Your equity has a earning ceiling equal to the prevailing mortgage interest rate.

I then sprayed two coats of mold killing, watertight primer on the walls, and a slightly different product for the ceiling.

(h) Floors, walls, ceilings, stairways and railings maintained in good repair.

A tile needed to be put back (drop ceilings) and there were two electrical issues.

I am not convinced yet, because of spilling a mug of water (single incident) should not have caused such a damage in the bottom house ceiling and as the person who lives in unit 76 has also quoted that there were leaks few times before we started living in your unit.This is the reason I want a professional guy to let us know whether it was a chronic problem (because of improper water proof sealing in the bathroom), which got aggravated because of that one incident or a mug of water (single incident) can caused such a havoc.Please clarity the commitments given by you earlier in email and settle down the deposit amount at the earliest.

Due to peaks in the roof, square footage is difficult to measure, but I believe it to be over 100 sq ft at areas with the ceiling over 7 feet.It is currently unconditioned space, so I was thinking of adding baseboard heaters. 

The reset rate for next 5 year term is 5-yr Treasury + 3% with ceiling of 8-9% (depending on loan).

I didn’t sub out drywall for the ceilings.

The oil burst up onto the walls and ceiling leaving a residue covering a large area.
