Wow ... mine seems pretty tame, but odd nonetheless.I had a tenant bring his own water heater (electric) and ask to have it installed in-place of the gas water heater for the unit.

True story & it may be a niche for you....Years ago when doing contract work at a GE installation (yep those 15 hr days) the little family run restaurant was a big hit.

If not, I would put down 6 mil vapor barrier, run nailers as John suggested, and install foam panels between nailers so entire floor is supported.

Ductless Mini Split A/C and Heat pumpUnits should be installed on a "outside" wall and not an interior wall.

Installers in general recommend their install on a new roof.We got our panels when we put on a new roof. 

For what it's worth, installed this product in my property and it looks fantastic.

About to begin a historic renovation project in which the owners want an elevator or lift installed.

Even if I only had to replace flooring, maybe the fridge, update the toilet to low flow and paint ... only spending 2K in the process; with missed rent, that is 2700.00 ... it will take 18 months to recover once the new tenant is installed at $850.00

Hi Brenna, I started with an installment contract at 19 (family friend), I'm 22 now, well, maybe a little older.... ;) Read all you can, you'll never stop learning.

I installed Tellus to try it.
