What they lack in curb appeal they make up for in steadfastness.

Do I have to go to eviction court, or can I just ask the sheriff to come put his stuff on the curb?

Curb appeal can work wonders and can be done cheaply.

I have found it typical for Owner's to pay for landscaping ($60-$100/mo) if they care about the curb-appeal of their rentals.

It is necessary for asset protection and curbing potential personal liability when dealing with others, typically tenants. 

Give your tenant a bit of a break in rent to take ownership of it (and the lawn/weekly trash to curb too). 

If so ... we stopped that practice Years ago.... you meet with client one time in office or home and get them pre qualed ... you then set them up on top producer or what ever on line system you have that gives them e mail alerts for their target property.. we have them do the drive by's ( this eliminates the houses they don't like because of curb appeal etc) and in our market the buyers usually have all the school crime walk score etc etc done themselves ..We then show up and only show houses they are really keen on .. rarely show more than 2 or 3 before offer is written.. and NEVER drive them in our cars. 

There's obviously price competition, curb appeal, and good management.

Plus I'm post-menopausal and getting meaner as I age.Gail

Google Earth shows a home with fairly good curb appeal.
