All of the bedrooms have plush carpeting for more comfort and the bathroom has been meticulously designed to enhance every square inch of space.

The parging has cracked off and there's some efflorescence that's eaten away half an inch or more of brick in an area about 10 feet wide.We plan on finishing the basement, so I'd like to address the moisture issues first and verify everything is good before we do any work down there. 

They hang a ceiling grid and install a drop ceiling a few inches down.

The moisture was obviously where the drywall shows being wet and the far right side 4-5 inches down the wall. 

I cracked open the door a few inches and that was when the wall of odor hit me. 

Unfortunately they are “give an inch take a mile” kind of tenants, so I’m having to do everything to the exact letter of the lease with them.

I would want to discover the extent of the mold by cutting about 18 inches off the bottom of the drywall in any suspect areas and viewing the wall cavity.

Just remember inch by inch turns into foot by foot which turns into you finally looking back and you have came a heck of a long way from where you are.
