How to find a value for a small park with a stick built home also

[Shelli Callan]

I am looking at a small mobile home park (7 spots) it is on 1.5 acres and also has a 3 bedroom 2 bath stick built house.  The park calculates out to being worth 235,200. (lot rent x 12 x 7 x .70 divided by .1) But how to I calculate the stick built home.  If it was not attached to the park. I have calculate the home with a comparable market analysis and come up with a value of $190,00.  235,200 +$190,000 =$425,200.  The asking price is $400.000.  So it looks like a good deal? But is it?  Is there a different way I should be calculation the stick built home?
