The yard didn't look unkept when we lived there, but the lady living there now has had cancer and hasn't been able to do much.
We talked to the woman who lives there now and asked if we could just explore the property. At first she was hesitant but then tested me with questions about the house and about when I moved. Apparently, I passed her test and she said we could come onto the property. Once we were down by the house, she said "you can come on inside."
