It was just kind of tinny.  3/8 drywall more easily hole-prone, cabinets made out of particle board with no top or back, hollow-core doors with cardboard 'struts', 2X2 stud walls, poly plumbing. plastic washerless faucets,etc. 

Tile Shops, Carpet, Hardwood, Paint, HVAC supply, Plumbing, etc etc.Thanks John! 

He simply duct taped the plumbing together instead of using PVC cement.

Interior and exterior needs an estimated $170k-$200k (roof, siding, windows, 3 porches front & rear replaced, new septic system, HVAC, plumbing and 3 interior renos).  

There will be brand new plumbing, furnace, water heater, new kitchen cabinets, bathroom, etc.

Finished kitchens, baths, hardwood floors, plumbing, wood windows, wood beams, etc

Plumbing work typically costs much less than electrical work, so I always advise to stay away from properties that have all the wiring pulled out or, if you run into any knob-and-tube electrical - no thanks!

One of my client's is being sued creatively by an adjoining retail condo for alleged illegal or negligent installation of plumbing. 

The 4 new apartments are going to need all of the interior framing, windows, electric, plumbing, heating and also new siding for the building.

I understand the need to use licensed/insured tradesmen for electrical, HVAC, plumbing,roofing and I will easily be able to obtain W-9, copy of insurance.However, my plan for flooring/sheetrock/painting/siding is to use sub contractors that may not be able to produce a legitimate W-9, may not have insurance, etc.Is this a bad decision?
