Where I live it is semi-rural. All the land around me is zoned at 5 acres minimum. Smaller lots can be grandfathered in but if you have a 9 acre parcel you can only build one house. If there are wetlands this restricts house building and well drilling even more.
We are on 10 or 12 acres and there is a 5 acre parcel adjacent to our land with a creek running through it along with associated wetlands. The parcel is long and narrow and the creek and wetlands run the length along one side. The side farthest from our land. There is a house, a double wide actually, that is about 50 years old. And two shallow wells.
Because of the wetlands on one side and our property line on the other side it is hard to build a house. The existing house in fact encroaches on the property line setback by several feet.
My wife and I would like to buy the parcel. Our son and daughter in law live there now. My wife and I bought our parcel 29 years ago, we occupied the house we had built 17 years ago, and have lived within 3 miles for 28 years.
Even with the wetlands and the crappy house and the shallow wells and the rural 5 acre minimum zoning the land next to us might be worth as much as 70 grand. Per acre. And my wife and I are willing to pay it. Not because we can make money from it, but because we will be able to control who lives there. And because we will be able to protect it.
In fact, controlling who lives there is only part of the reason we want the land. The extra land next to ours would give us more land to build walking trails. And the wetlands would be included in the trail system. My wife and I both love the wetlands. There are no fish as far as we know but lots of frogs. And the water flows year 'round and because of the topography a pond could be easily made. And our trails could be connected to trails on some neighboring property, trails that we already have permission to walk on. Also, as I said previously, we can protect the land. It is a nice parcel and we don't want to see it get logged off. Or have neighbors who dump all their garbage on the land. Stuff like that. If we own it then we can do our best to protect it. Like on the land we own now where we use no pesticides or herbicides.
The upshot is that there are lots of reasons to buy land. Making money off of the land right away may not be the only reason to buy land. In our case we plan to never make money from the land. We expect to give it to our son and his wife when we die. Land is different from other purchases because there is truly a finite supply. Even so the value can change for many reasons. Zoning changes, the economy, the proximity of new shopping centers are all examples of things that can cause drastic changes in valuation.
So you need to decide why you want the land, then you can decide if you want to pay the price. I know that if we are able to buy the land next door we will really have a hard time parting with the money. But a few years later we will be glad we made the purchase, especially me because I will have 5 more acres to use my tractor on.
