You want to put yourself in a position where you sit down at your desk and review several new acquisition candidates directly from the seller each day.

I'd be interested in anything which might cross your desk for Metro Chicago.

In the midst of the tour, he showed me his shower, and the LIGHT SWITCH that used to reside in there, but has now been relocated because that is slightly out of code.

Get to know those guys at the plumbing/electrical desk.

I hear someone say, that desk is mahagony, and I go, "ok.... why is that so special?"

Including doubling or tripling wall outlets and installing 3 way light switches where two door rooms are located. 

3) motion/timer light. 

I would recommend doing a few searches here as there are a lot of threads on this topic that will shed some light on things.

Hiding is not realistic especially in light of the fact that you require the tenant to fully identify themselves.

Try to have the mailer land on Tuesday or Thursday (light mail days)Make sure it lands after Wednesday and before Sunday (people are more receptive and happy toward the end of the week)Try to get it to land on the weekend (people are more likely to open and call you because they have free timeWhat had been your experience?
