I'm going to be putting tile in a duplex and I want to know what material will hold up the best.

Would you recommend purchasing the material and just bidding out the work or paying someone to do things turn key?

I'm looking for a sources to find good solid study material on the subject.

Same for replacing paneling with Sheetrock, lots more finish work at all doors and windows due to thickness of material.

I don't see how anyone could learn the material in 1 or 2 weeks of classroom.  

Mark Paup ,Just from a contractor's perspective, I would get the full seller's disclosure, and make sure there are no asbestos materials (tile, loose fill insulation, wrapped pipes, etc) and make sure there is no lead paint.

Then, build a pergola straight out from the wall to completely cover the entire deck, with two fat supporting columns at the corners.The least expensive way to create interest with the entry leaving the steps as they are, would be to build a "shed" roof sloping toward the front yard, over the landing... maybe use a cool standing-seam roofing material.

I plan to own this house for up to 20 years as a rental.The prices I have been quoted are $3,500 and $4,000 total for time and material.

Have them break down each of their costs; materials and labor.

As long as you close, it isn't material to the deal if you have financing on the HUD-1.
