I have just found this to be a way to find their deeper motivation for selling the home.

Hi @Bill Tyler No legal advice at all, and your emotional attachment may be completely different than my thoughts :) You could contact the other 15 heirs and see if they all wanted to pay $200 and do something together with the land (sell/invest/build/make a park for neighborhood kids/give to the local Lions club)Keeping in mind that with 15 of you even at $18000 the total is $1200 each if you sold at market rates.

Just a turn of phrase, but it's better to look at it from a neutral emotional state as an investor.  

You CAN request documentation for "emotional support animals", which DO have to be prescribed by a physician to be covered by the laws, but do NOT have to be trained in any special way.

Given the topography, I don't think it could ever flood any deeper. 

Buyers have a whole lot less imagination than you would think, and you sell on emotion first, reason second. 

Perhaps my almost "emotional" attachment and excitement about this property is clouding my judgment.

The numbers of the deal should be the determining factor and not emotion. 

“Owning a home is a keystone of wealth… both financial affluence and emotional security”.

Let's not get emotional about it, just do the math.
