The first thing you would do in a cash for keys situation is explain to your tenant what is happening. Explain that you want them to move out and if they do not, you will evict them. Let them know how an eviction can harm them in the future and explain that it will likely be expensive for both of you. This is why you will pay them a certain amount to move out now. This amount can be whatever you decide, however it is often suggested that somewhere around $400 or $500 will do the trick.
Next, explain that you want the apartment cleaned and any repairs done or paid for by the time they are ready to leave. Let them know what date you want them gone by. Make sure that you give them enough time to get everything out, but not too much so that they could do more damage. Always give them a notice, as this would be the first step in an eviction as well. Keep a copy for yourself. Once they have moved their things out and cleaned, go in to inspect the property with them to make sure it is in the condition you asked. Take pictures of how it looks. Now all you need to do is have them sign paperwork that states that they are officially moved out and you can hand over whatever amount of money you agreed to pay them.
While this may seem odd to pay someone to leave your own property, it is often much cheaper than going through the full eviction process and helps your tenant out as well. Let us know what you think about this concept and if you have ever used it.
