Is this something I should hire a lawyer/other professional for or can I just do it myself? 

Who is the Lawyer against them? 

Have someone physically there to check on the property and partner with them, etc.I'm not a lawyer and this isn't legal advice, but foreigners can setup US business entities in the United States, and not have to be physically in the United States.

yup the foreclosure rescue buy back went away in 08 in Oregon..  1. you cannot do a foreclosure rescue and rent back at all that is illegal in Oregon.2. you have to be a licensed foreclosure agent to advise on those in foreclosure those licensed are RE brokers  MLO and lawyers.

So, do they really want to hire a lawyer to try and fight you, and have their credit wrecked in the meantime and have a terrible landlord reference? 

They are lawyers so can appeal through the whole process essentially for free.

The article also fails to mention that overall transaction costs can actually be higher in countries where commissions are lower because the agent plays a different role, and due to needing to pay a lawyer for paperwork that agents complete here as part of their job (called a solicitor in Britain) plus VAT taxes and other closing costs need to factored in on top of the sales commissions, which we don't have here, overall costs can actually be higher even if commissions are lower. 

I am not a lawyer so anything I say here is not legal advice and your contracts should be reviewed by an attorney.2.

Can a lawyer do this or this has to be done by an accredited IRA accomodator?

I know I can go through a lawyer but I was told it is a fairly simple process hence want to DIY.Regards,Xuming
