There are several things that may make you, as a landowner, to consider selling off a piece of land.
One thing that may make you consider selling a piece of land is the realization, at that given point in time, that the land market in your area is actually undergoing a boom. The idea would be to sell the land off during the boom, rather than waiting for a ‘bust’ to take place, and possibly end up selling the land at a throw-away price.
Another thing that may make you consider selling a piece of land is the realization that you can get better returns by selling off the piece of land, and reinvesting the money in something else. This is where, for instance, you can sell the piece of land, and use the proceeds to develop another piece of land you happen to own elsewhere. This is also where you can sell the piece of land, and invest in some sort of business. In this regard, you can use the proceeds from the land sale to, say, buy some good vacuums for pet hair. You could also use the proceeds from the sale of the land to buy the model of the best cordless vacuum cleaner for carpet. Then you can resell the vacuums (or whatever else you buy), and end up getting better returns than you’d have gotten by continuing to hold onto the land for, say, speculative purposes.
Yet another thing that may make you consider selling off a piece of land is simple lack of money. This is where you run into financial troubles, and you realize that there is no point in continuing to hold onto the land, while you could sell it to get the money you need to finance your day to day living.
