I did once have a tenant who didn't keep the place in what I consider "showable" condition (dishes everywhere, clothes on floor, dirty bathroom, etc).

As to the grease, buy her about $10 of dawn dish soap. explain that even a little grease can clog a sink when it hardens.

I also managed Dish contractors in Richmond and Virginia Beach.

But you would have to be ready to dish out $1k per month for possibly 1 or 2 deals (depending on your market of course) but that one deal (again depending on your market) can net you $5-10k.

While I agree with Luke, get your systems in place and you can lean heavily on technology, you will still want someone nearby to check-in on your place, make sure it didn't get trashed between guests, replace inventory (dishes, glassware, tp, etc), make sure there are no leaks, running toilets, broken down AC...
