Carpet throughout the main living areas, vinyl flooring in the kitchen and bathrooms, microwave, stove, refrigerator, dishwasher, fenced in patio, and fireplace.

Next time you are there, check to see if the Pergo is buckling/peaking a bit at the seams--that's a sign of moisture.If this is to be a rental, I'd completely rule out carpeting and look at vinyl planking--it's water proof, and easy to maintain and repair. 

In the last ~2 years we have upgraded ~220+ units and our flooring in the bathrooms has always been either TrafficMaster Allure Vinyl Plank (the stick down flexible product) or 12"x 24" Porcelain Tile all depending on our budgets/community demographics. 

Has anyone installed LifeProof vinyl plank flooring from Home Depot?

I probably paid another $25.00 for PVC, toilet flange, roof jack and other miscellaneous stuff I didn't already have.

You can do that too, just be prepared with a storage space/warehouse or to get lucky on a lot of material.It's easy enough, just follow back from the guys that buy a lot of material in your area to the distributor to the manufacturer.I listened to a podcast one time with a guy who was rehabbing 100's of units of apartments in Texas and he started his own wholesale building materials company and was buying containers of vinyl tile from China and was selling to other apartment rehabbers in Texas.Could you do this?

The aluminum frames look very thin which helps with the view, and a vinyl replacement would probably have thicker "framing" and would block some of that view.

He added a small patio room and roof caused a leak in the kitchen due to them putting vinyl floor title as shingles (A fix I had to pay for). 

., he proposes laminate counter-tops and I want Corian, he proposes vinyl flooring in the bathrooms and I want tile?)

I can't quite see, but it looks like the wrong PVC fitting coming from the Laundry sink to the horizontal.Original kitchen is ok in this area, but I would have replaced the hinges and pulls with a newer style.
