Needs help with Section 8 issue

[Ori Foyer]

I bought a Section 8 property on December 2017 and planned to flip it. The tenant requested to stay in the property till the end of June 2018 and I agreed to it. Since that changing Section 8 property owner required a lot of documents and bureaucracy, the previous owner agreed to transfer me the rent checks he receives since January 2018. The agreement was o.k till May. Since than the previous owner stopped to answer to any phone calls, text messages and emails. The tenant moved out at the end of June and the previous owner owe me $2274.

There is not written agreement between me and the previous owner and it is one of the lessons  I learned from this issue.

My attorney told that his work fee on this case will cost me much or less the same amount that the previous owner owe me.

Is there anything else I can do to get my money back?
