If I ever got tired of using it as a vacation home it translates easily into a regular profitable long term rental, or because I bought in a neighborhood with low HOA and attractive to home buyers, and paid a reasonably low price/sf, I also have a good sales exit strategy.

I was surprised the other day on FB I saw a lady make a post for her neighborhood and just said something like I need a job that is 1st shift and pays at least $26/hr...that's what I make now, but working 12hrs a day/6days a week at Frito Lay and I'm tired...just want to work 8hrs in the morning. 

I am getting tired of all the things I have to do to make it a safe/functional place to rent.

The sellers financed each of those houses, and both of them were tired landlords. 

I am extremely "burned out" with my current job that pays well but I am 62 years old and very tired of making other people rich.

I would caution you in your use of it because by now, it's a tired, overused assertion.

A battery, alternator, brakes and tires are much less than car payments.

Tired/sparse decor will not cut it, even though technically you might have superior "amenities" than other listings. 

They learned how to work and how to work tired. 

Otherwise stated, what information does one need in order to weed out the so-called "tire kickers" -- sellers who are unlikely to sell at the kind of discount needed to make a deal possible?
