Rental with .4 acre back yard & huge garage?

[Aaron Hollingshead]

Hello, 

I'm about 2 weeks away from putting my first rental on the market.  If I rented it as is, I think I'd fetch around 800 dollars a month - it's a 2 bed, 2 bath, 1350 foot place in a B-ish type neighborhood...the back yard, however, is .4 acres and there is a garage/work shed which is large enough to hold 2 RVs...I'm wondering how I might maximize my income by utilizing both of these spaces.  Also, if I don't make money off of the back yard, any creative ideas for maintenance at a good cost as I don't want to worry a bout having it mowed, kept up, etc?  Thanks!
