Preparing for possible Eminent Domain buyout of my small MHP

[David Starr]

Examining highway expansion plans it appears the highway dept will need most or all of my small MHP (15) lots, all with park owned homes.  Park and homes are  free and clear.

Reading online and talking with my CPA I understand when an offer is made the first one will be low ball.  Ok..I get that.   I also think they (highway dept) will only be interested in the land and not the mobiles. 

The park is an income producing asset which I did not plan to sell and would eventually turn over to my children.  For the most part my wife and I are living off of the income.  I'm also at the age that I prefer to not start another park...nor have 15 mobiles for sale.

What is best way to arrive at a fair value..and get it?  

There is a lot of experience on this site and I would appreciate ideas, thoughts, experiences, strategies...etc.

Thanking you in advance.
