-eat-in kitchen needs baseboard [b]( Use cove base, cheaper and more durable)-refrigerator [/b](If I supply them I wait until someone pays a deposit to move in)-dishwasher [b](I don't deal too much with them, used ones are about $100, make sure they don't leak if you go used)-bedroom (converted sunroom) has ugly vinyl floor - replace with carpet?

The reasoning is that you will accomplish the same end goal (a durable water resistant surface for your rental's kitchen) but have flooring that will truly take a beating from renters.

I like it better than wood because it is more durable and less maintenance

What thickness/durability rating do I need?

Still runs great--Toyotas are durable as hell!

Yes it get's dirty, but it's easy and cheap to replace, and if your renters are semi-clean people, there's a good chance you'll be able to get away with just cleaning it when they move out.For house #2, always do tile in the wet spaces (kitchen/bathrooms), relatively cheap, durable and easy to replace.  

@Leonid Sapronov Hello Leonid, installing LVP is a great option for rentals and worth the money when holding as it is very durable, easy to clean, and also looks high end.

Remember everything in a rental need to be very durable or it's sure to get broke, even then, some tenants still find a way.

More durable than sheet vinyl.Neither are even remotely as durable as ceramic, so plan to replace as needed, but for a DIY install it doesn't get much easier.
