Hiring everything out or diy?

I want to DIY it, but I also want to do it the easiest way :).

What flooring is best for a rental- I don't mean cheapest or most attractive or even easiest to install- I want something that's going to last, something that is 'tenant proof' as far as damage.

It's hard to say where the smart lock journey is going but the company that stays flexible and evolves to create the most compatible (door- and lock-types), easy to install, maintain and use solution, will be around in years to come.

@Mark Byrge - I'm having a new system installed on my facility that is web based.

Thats what we install in mobile home parks and apartments.Its well built, fixed based radios that send you a water reading 2x a day, and it has leak detection. 

If you think she is a pain now wait till you start installing a fence.

I can have a furnace installed at cost (3k).

Furthermore, I doubt that the pier is physically tied via post-installed anchors so there's no lateral resistance or moment transfer.

as there are some issues due to water wetting the floorsRepairing wood floor cost seems almost comparable to installing new vinyl tiles however I will have to forego substantial existing subfloor and I am also not sure about roi with vinyl flooring (not sure if home value appreciates or depreciates).repairing wood floor also doesn't seem like a good idea as its not as durable and water resistant as vinyl I am confused please adviceThanks
