Is eviction the next step ?

[Brit Foshee]

I purchased a REO property at 3rd party auction knowing that the previous owners were living in the property. This house was foreclosed on in August of 2013.

I've driven the property several times just to get in contact with the occupants.

1) They are never home.

2) When they are home (usually at night, lights are on) they don't come to the door.

The last time I was there I left a letter on the door stating I was the new owner, and I would love to work with them and hear what their plans are..... please contact me at this number.

Still nothing.

What is my next step ?

Can I legally start the eviction process ?
