Oh do tell who this mystery person is Nick...there are only a handful of people that have increased their activity a lot lately.

@Patrick Philip For a remodel, I think it would be near impossible to get a full one-piece shower/tub unit into the house, thus you dont see them very much in the big box store.  

if you are handy, the install should cost you about $200-300 in material, for a standard system, but for the next one i do im gona try Tjernlund RX2 system, they are $229 and install in a box sil, its not a "approved" system, however their is no "code" on radon in WI just guidelines by the EPA if it accomplishes the result, Im all for it instead of 3" PVC into the floor and out the roof. just my opinion. 

Ok guys so i went to go see the houses and the investor was unable to accompany me so i had to go alone, here is the info.House 1 :  2bed 1ba , 448 square feet ARV 150kRepairs Wasn't able to get into this one the realtor said they changed the lock box.

Is there a breaker panel or a fuse box?

You can get by with really cheap PVA primer from the big box stores, the coat does not have to be perfect, but if you don't use it, paint won't look the same on the drywall mud vs paper surface. 

Still may require some adjusting to them as you have it.Good luck though and good thinking outside the box (Just make sure you can in your area legally)Not legal advice blah blah

You can find an 18-guage NOMA rated low voltage 2 (3, or 4 wire if you want to pull multiple connections in a single run) in 50, 100 and 500' spools at any big box (HD) or HVAC/electrical supplier.

I kinda like it, I would however maybe permanently block the fireplace, by putting a cheap electric unit in the fire box, unless you dont mind if the tenant burn it down. 

. :)So the legal box is check-marked but the homeowner can still use the property as he/she wishes.
