Yards and the exterior we require, for example, yard maintenance at a minimum every 2 weeks, with no "indoor" furniture allowed outdoors including on porches, and no stored items, no car parts, construction materials, or vehicles that are not currently licensed and operable.You can also require annual professional carpet cleaning in the terms of your Rental Agreement.

We look to ease that burden, and help prevent indoor accidents, by having fencing in the back yard so the tenant can just open the back door to let doggie out whenever, come back in when finished, no big deal.It seems like a good amount of houses we look at already have a fully fenced backyard or are 3/4 fenced and we can just quick add in a bit of chain link with a gate and good to go.
