Tenant wants to build fence

[Amie D.]

I've got prospective tenants that want to build a fence for their dog, at their cost as they've got a friend who builds fences for a living that could do it for them.

My prop mgr thinks it is a plus since a fenced in yard adds to prop value esp. since I allow pets at this house.

I don't mean to be negative but I'm leery of it. They could build the fence improperly, as well, without a survey I don't know where the exact boundary lines are, which could cause issue upon a sale.

Am I being too negative or? Their full application hasn't been processed yet so this is still preliminary.
