Ofcourse I am planning to consult a lawyer first. 

I've heard about rocket lawyer, do you recommend anyone?

There's a few other exceptions such as a tax lawyer, but I find that a lot of folks find comfort in just having me respond to any notices that they might get.

Basically the cost of the lawyer would ultimately be as much as the money they scammed me for.

Talk with a real estate lawyer as this may work a little different in each state. 

Like a rich uncle or friend of the family doctor/lawyer?

You'll also want a lawyer to draft up the docs for you and register your mortgage on title of the property being lent on along with the promissory note.  

We worked with a lawyer over there who is a US ex-pat who created and registered a local LLC for us, which owns our properties.

I consulted with a real estate lawyer a few times this year who said it's very hard to sue for negligence and they advised against taking legal action, especially since the property manager at least followed through on the eviction and repairs.I've now asked the property management company to apply a $4k credit for all the challenges I've had working with them.

Would that look like a partner, General Contractor, CPA, Lawyer?
