You need to know as accurately as possible what the market will bear for each unit and what a great price really is.

We meet in downtown Hagerstown at Bulls and Bears from 6pm-9pm.

before doing the construction on a building that is going to serve as a fast food restaurant, you could market out to potential franchise owners and work a partnership or just sell them the bear lot.

@Chris LeiningerWhat they "paid" for it has no bearing on anything whatsoever.

Some topics that have been brought to my attention are:-timber sales, soil mining, solar power generation (solar farming)As of now, there are two separate tracts of land with potential opportunity in two separate states in the SE (USA) I am looking at.

More about quality tenants later.You could segment the curve by job/income level (The following is a silly segmentation but bear with me.) as shown below. 

I just want to see what the market will bear on the house as far as a sales price.  

Is it steep, flat, sandy soil, clay soil?

In that process, the tank could leak and you're in a world of hurt paying for soil remediation. 

The investment to date is a sunk cost and has no bearing on future returns.
