So that the owner of the vacant unit will get tired too and will just forgo the property.

Drive for dollars, cold call, go down to the courthouse and talk to owners evicting their tenants (tired landlords) although if you are doing all that stuff and educate yourself on BP maybe you don't need to work for someone else?

They got tired of waiting so they rented from me. 

In that case you could offer a bit more for the property and you'd have your OPM lined up for you.Perhaps he says that he is tired of this property and wants to lighten his portfolio of 'C' properties, he'd be willing to negotiate the price with you and what would you like to offer?

Having multiple people show up at the same time will make those truly interested act and the tire kickers probably won't show.

As I got older, went back into commission only sales and tired of the hassle.

Im getting tired of this perceived emergency of AC repair so Im thinking about changing my lease to include clause about AC repair to emphasize that no AC repairs are possible during the weekends and federal holidays.  

I've grown tired of the slow gains in equity in the market, and thus have decided that maybe real estate investing may be a path to my future investment strategy.

This got to be a pain in my butt, tired of dealing with the tenants every month about the water.  

Mostly from tire kickers.
