You should be familiar with material costs, suppliers and time required for a job so you can judge any bid.

The $6500 is in materials.

He also works for a marble company where he is able to get a lot of material for countertops, floors and other for less than wholesale.I have not done any of the work however I have paid 100% of all costs.The questions that are coming up now are:Do I stage the properties when we are going to sell?

He can purchase the materials at cost.

Costs for plumbing is going to depend on how much material and how hard it's going to be to get it in place.

I invested cash and my return has been quite good.I have not had HOA issues or assessments although I keep a large rainy day fund in case it comes.I did have competition from other units but I remodeled a tad higher taste (just a good combo of construction materials, nice colors and good workmanship) that appealed to the aspirational side of enters without screaming expensive, nor being expensive to me.I rented all units in a matter of days.

Are all the materials you are buying through Menards or Home Depot or are they specialty stores?

I would be covering more / all of the down payment, while he would be buying materials and covering labor costs. 

Another thought is I can probably find a local Contractor to GC the job and pay a "fee" to allow me to do some of the work myself but he'll include the materials in his draw requests.Any comments are appreciated. 

I knew each night I needed to spend at LEAST 1 hour on the phone talking to homeowners.This meant: STOP over-checking e-mail, STOP reading online, STOP “gathering materials I would need before I could make the calls”, and NOT put down the phone until I had made my calls.My motto at that time which I said to myself over and over again was, “Nick, SHUT UP and DO IT.”
