What material is the exterior?

And, I have been told that I am not investor material in terms of my approach to tenants and personality. :-) Therefore, I am seriously considering property management for my next lease term, whereby I start treating this as a business than a charity.

I will be deligent and go through all the material. 

Within each set, there's a fair amount of options for selecting different styles and materials.  

Cost of materials was way low and cost of install way high .

Either want them to fix material deficiencies or get a credit for when I will have to fix within 6-12 months.

For example, if you expect a bid for "800 sf of 3.5" wide, 3/4", #1 solid red oak installed and site-finished with a Minwax stain and three coat of poly (labor and materials)," and the contractor hands you a bid for "hardwood in the living room and dining room" -- you're probably in trouble.

The easiest way for the industry to setup IRA's is with mutual funds which of course are promoted by the big mutual fund houses.  

Since I am starting from scratch I see there is a lot of material to read to get up to speed. 

For those of you who purchase your own material, I would like to know where you are purchasing your PEX supplies at?
