Advice on asking price/ value of access?

[Sue Wilcox]

We have a been approached for an easement across our property (our primary residence). 

We own most of the frontage to a parcel of land (32 acres with a winding river through the middle) abutting ours..that just sold for 120,000. I found out that they want to put a 30 site glampsite including a lodge, showers, bathrooms. They have the money to make things happen quickly.

*We would rather sell our entire property and move..we prefer not to have so much activity in our backyard.We would have to find a place.

*If they bought our land and house they would gain:plenty of frontage closer to the site..easy access for water, electric..If they want to run it.

*combined with theirs an extra building lot would be created 

*Our house..which is an antique cape completely rebuilt after a fire.

* It would make their land into a more cohesive piece.

The access that they currently have is challenging..it would cost a great deal to get water and electric that far ( if they even want to do that). They would have to sturdy up the existing  farm road (with is squeezed between river and our property).The farm road is about 25 feet away from the river, the banks of the river are eroding an average of 3 feet a year.

The long and short of it is...owning our land would make their land much more valuable. 

So far I've told her that she has a very creative idea..but as an abutter I would be concerned about having stranger in and out constantly. I said we wouldn't give them an easement but would consider selling..as we don't want to be on the edge of all this activity.

We have an appointment to talk to them tomorrow.

I'm trying to figure out how to determine an asking price which I know they will be asking. Any negotiating tips are greatly appreciated!
