Don't fight the market, EMBRACE it's opportunities. 

Higher frequencies don’t penetrate much and aren’t nearly as noticeable.

Insulation and fire caulk at all penetrations through the celing into the attic.

Completely agree with those points, for me my partnerships are all about penetrating markets (language or otherwise), learning and benefitting from others' skills, not re-inventing the wheel in a less efficient and more consuming way, and being able to free myself (regularly or temporarily) for "higher" pursuits more directly tied to my skillset or needs (in my case, managing clients, getting new ones, creating new partnerships, and of course private pursuits).

Tenant shall be responsible for repair of any resulting damage, including water penetration. 

If you had two inches of sewage in this room and it set there for 24 hours, the water almost certainly did penetrate the sheetrock and into the framing.  

Your young embrace the learning experience. 

Don't get me wrong, I embrace the constructive criticism because it helps us grow and improve, however, to call us "scammers" is extremely inappropriate and unprofessional.

Good for him, embracing the wankit name!

I want to try to penetrate the area with some multi family rehab projects.
