Interestingly, look at everybody jumping to the tenant's defense on the Portland news site KGW and blaming the situation on the landlord.http://www.kgw.com/news/tenants-leave-behind-25-tons-of-trash-at-portland-rental-home/177131842

There are websites like Rocket Lawyer or Legal Zoom where you can communicate with an attorney for a very nominal fee about your specific situation.

FWIW I'm more in your situation with full time job etc so I started with rentals to build up my reserves for larger deals.  

I was more so looking at a buy, rehab, and rent situation, with the possibility of flipping depending on the metrics on the buy.

An ideal situation is for the now seller/landlord or you to draft a document that states the tenants must vacate within 15 days after closing, have them sign it and then leave that as the now landlord's responsibility to deal with, its his mess, and then also have the landlord pay you (escrow) PITI + security deposit + expenses 10% during the period these tenants are still in there (refunding the security and expenses if not needed back to the seller). 

That way if the rehab takes a little longer or if selling takes a little longer, your profits aren't eroding (not to mention the added stress!)

More importantly, a GOOD realtor who takes your criteria, financial situation, short-term & long-term goals into consideration is going to be a huge asset to your REI career. 

Love hearing more details on stuff like this as I am getting into similar situations soon.  

Take Mom & Pop and your friends and go shopping...look at tiles, and light fixtures and your new furniture and all that fun stuff.Leave the stress with the realtors and attorneys and just enjoy the ride.

Tim,I wanna be a little more clear about your situation.
