The house owner came through! We had a feeling she had talked to them (DH talked to her Tuesday morning) as all week they had stopped parking in the street. Since the guy doesn't get home until like 10pm every night we figured if they were going to clean up it wasn't going to happen until this weekend. But, he got home about 8:30 last night. Obviously, none too happy as he's driving fast and screeches his truck and trailer around the corner and comes to a screeching halt in front of our houses. His wife had hooked her SUV up to one of their smaller trailers and moved it over to the side of the house. He pulled in with his big car trailer and loaded up one of the junk/non running trucks in his driveway and hauled it away. Then he came back with with no car trailer and loaded some stuff in the back of his pick up and left again. (when DH had talked to the home owner she said when she told them to get it cleaned up last summer/fall he had told her he had a friend on the other side of town he could take it all to....just didn't tell her he brought it all back after we bought our house).
It looks SO much better already this morning! They also had this rusted, dirty, crappy looking, what I think was one of those big BBQ's that sit on a little trailer just sitting on the side of the street - it was actually sitting on the vacant lot on their side, not even on their property. That appears to be gone or moved too. Just having them not park a car or two out in the street 24/7 is a big improvement on it's own.
I'm very glad we persisted and pursued following the covenants with the owner of the house. Sure, the renter guy won't be too happy, but that's not our problem. There was absolutely no reason he should have been allowed to have what amounted to a wrecking yard - small town or no small town. DH is going to give the home owner a call soon and thank her for taking steps to get this cleaned up. I'd say it's about 85-90% cleaned up now, so that is very nice indeed.
