#1. Swamp Land with a Dry Island
If you don't mind the mosquitoes, swamp land or marsh land is an excellent option. What you want to do is to find a large swamp that has a dry section in it, effectively an island, and the only way to get to your island is via a boat or plane. (Or hovercraft...)
You then build your home on the dry land, and because it would be impossible (or at least unlikely) for the Ontario government or electricity company to ever want to build electricity poles out to your little island, they will just leave you alone - which means you pay less property taxes by being off grid.
Alternatively, lets say you buy a swamp that has ZERO dry land. Instead you can build your home on stilts or even have a boathouse.
#2. Secluded Island
A good example of such islands in Ontario is any number of islands in Georgian Bay, but the truth is there are many such islands in the vast wilderness of Northern Ontario that you could build on.
It doesn't even have to be a big island. Any large enough chunk of rock will do.
#3. Very Isolated Land
Imagine buying a piece of land that is so isolated there are no roads going to it. The only way there is via plane or helicopter. Or snowmobile, 4-wheeler, or some kind of similar all-terrain vehicle (cough cough, hovercraft).
Typically this would be a piece of land so far north it is deemed "too cold" and "too isolated" by many would be home-buyers, but if isolation is what you crave such a home would be good for you.
Because it is so isolated you will have to rely on getting most of your building materials from the rocks, wood and clay that you find near your home. Transporting building materials to it would be excessively expensive. So if you also want to DIY, a piece of very isolated land is the way to do it.
#4. Land Most People consider to be Useless
There are a variety of reasons why some people might consider a piece of land useless.
- It might be on a flood plain and get flooded at least once per year.
- It might be right next to railway tracks and be very noisy multiple times per day.
- It might be too close to a major airport, and likewise very noisy.
- The land is unstable due to sinkholes.
- A piece of land so small that most people consider it to be useless.
- Complex legal problems with the land (eg. A piece of adjoining land is currently stuck in a legal grey zone such as wherein the city technically owns the driveway of the property, and thus you don't actually own your driveway.)
- Any number of reasons.
- Flood plain? Build a home on stilts.
- Railway tracks or airport? Build your home underground and soundproof it.
- Property has sinkholes? Build a shipping container home underground inside a sinkhole that has already collapsed with horizontal beams that stabilize the home.
- Really tiny property? Build a very skinny house. (And then don't attach it to the local sewer or electrical system.)
- Legal problems with the driveway? Don't use the driveway, instead get a bicycle or a Paramotor*
* In case you are wondering, this is a Paramotor. Who needs a car when you can fly?
#5. Very Mountainous or Rocky Land
Good luck with your sewer or water systems with this particular location. Or electricity.
If a region or property is basically one huge rock it is tricky to build on it. Tricky, but not impossible.
To get electrical poles out to the home a person would need to drill holes into the rocks to place the poles, and the cost of doing so - depending upon on how far away from electrical grid the home is - makes it unfeasible.
Thus solar panels and wind turbines suddenly make more sense.
So there you go. Five types of land to consider when looking to build on cheap land. Enjoy!
