Rental with large yard. 1 acre.

[Austin Bauer]

Looking at a single family home I could by for an awesome price but it is on a lot which is over an acre, located in the city.  I have one rental currently with a small yard and tenant mows it and supplies mower.  

 Probably get $1000 in rent for new property.  Wondering how to handle mowing situation.  Would require a rider.  Seems like options would be.                                                           
                                                                              Sell tenant rider cheap and have them mow it.  I don’t want to own mower for liability.                                
                                                                       Have them supply push mower and just mow perimeter of back yard.

Your thoughts?  Thanks!
