another 6 inches & more frozen pipes...

The windows are currently louvered windows (6 inch wide), basically the leakiest possible windows, which was great before air conditioning, but not great now.Anyhow, tenants AC bill is really high in the summer.

A very small nap mohair 3 inch roller cover works great for laying down a nice finish.  

As soon as you can, rip all of them out and replace with the traditional three 1x4 or 1x6 ledger boards. a 3/4 in. plywood shelf, and a 1-inch steel closet rod and flanges (not an adjustable rod, one that you have to cut to the right size), all screwed into studs.Tenants will always overload their closets with their crap.

When myself and the contractors went into the apartment to look at the windows, we noticed the tenant had his bed  situated  roughly 32 inches away from the window.   

To achieve R28+ in walls requires use of a material such as closed cell foam (~R6 - R6.5/inch) or polyisocyanurate hardboard (~R7 - R7.6/inch).

this example means the house is 2.5 feet lower than the BFE Base Flood Elevation, even though it might be only 4 inches above the ground level.  

its a big 3 inch cast iron stack that would require 2 walls and a ceiling demo'd to replace, its catching a full bathroom and kitchen.

While it's typically dry with minimal rainfall (around half an inch over a few days), prepare for cooler weather as winter approaches.

You'd essentially be renovating your way to lower cash flow.most stackable washer/dryers have a 30 inch square footprint (6.25 sqft), meaning they can be placed virtually anywhere.
