I beg to differ regarding self -eviction by landlord. I own several properties and all you have to do is go to your county courthouse to file the paperwork. If the property is corporate owned, THEN, you need a lawyer.
The process is simple and there will be filing fees associated. Also, be sure that you know exactly how much the tenant owes in past due rent, utilities, etc. Once the paperwork is filed, the tenant is served. My experience has been that they do not show up at court and you will receive a judgment. Collecting on that judgment can be difficult, though. You also will have to prove that they are not in the military. It's not all that difficult.
If you send me your email address, I can send you out a copy of Truth in Renting so you know how the laws affect your ability to evict.
