I am considering dividing the property and OWNER FINANCING   2 acres and the housebut, I don't know how, what, when, where ...LOLmy question is Do I get with an attorney to write out the terms then advertise it as owner finance?

I would step out and guess that you would want to find an appraiser and surveyor that has experience with subdividing land, but I'd guess they would take the 5 acres and figure out how to divide it up to be most profitable and than give an appraisal on each parcel using similar comps. 

@Mario Lanza Yes, for a $100k loan interest for the year would be between 10k and 15k, divided by the number of payments per year.

Can you sub-divide along the zoning lines?

The house crosses the original dividing line between them, so I'll need to get a survey and do a Boundary Line Adjustment to re draw the new line.
