Because a yard sign or a craigslist ad will generate plenty of calls.You say they're reliable and will be a good tenant. 

Had easy back yard access.  

Yard sign, logoed open house signs, door knocking, open house flyers, just sold flyers, etc etc

My former wife used to teach elementary school located next to the Santa Ana River and cranes would occasionally grab them in their beaks and some of the catch would land in the school yard, only to be discovered by kindergarten kids with puzzled looks on their faces.

My wife might be my back up tommorrow unfortunatly oppossed to two large male German Rottweilers that I planned on having tag along while I complete renovations tommorrow down their with its fully fenced in yard.

Below is a link to yard signs hope it helps!

If you ever decided to hire a manager, I'd start with the resident with the nicest house/yard, the one who pays on time every month, and the one who calls you when there is a problem in the park.

The area around it has a lot of scrap yards and such.  

The result was needing a clean out installed which required the front yard to be dug up and the lines then hydrojetted. 

If you remember what bank/agent had their sign in the yard I would call them to find out what happened.
