This is when a nice spreadsheet will help you visualize your cost/benefit analysis.

And especially for the visual :) I had already painted the garage door a tan(ish) color to try to make it blend in more-- do you think I should go back and try white instead?

I learned not to show units while occupied, mainly because applicants can't visualize their stuff in the apartment, if the current tenant's stuff is still there.  

There is only so much I, or the real estate agent can do with words for them to try to visualize the place in a normal condition.

Its almost impossible to prove either way, but could be a deterrent for some.  

A better way to visualize the strategy is to do exactly what @Jeremy Z. said. 

Alexi Correa Hahaha I can visualize you yelling it out.

People are visual beings and are more inclined to make an offer based on what they actually see as oppose to the potential.

I prefer those documents to be sight-translated... that means the document is read from the source language (in our case, English) and interpreted verbally (for spoken languages) or visually (for signed languages) into the target language (the language of the tenant).

Sue has some great techniques to help detect/deter renting to illegal immigrants.
