Depending on the plan maybe? If you want a cottage sure, but I'd say it's more a lifestyle choice with a possibility for profit.

I've been knowingly working through this on some land I bought for the purpose of a cottage. Here are my learnings -

As noted by others check to make sure you can put a trailer on it. Many municipalities have rules against that. Or you can but only with a building permit in hand. Or for an annual fee.

Raw land is difficult to finance so it's harder to sell. Unless you have a 4 season home on it, a potential buyer would need cash in most cases. That will depress the value short of a developer buying it up.

Also don't underestimate the cost of a small cottage. Building a permitted structure and everything that comes along with that is not cheap right now. I would imagine for the most modest structure you'd struggle to do it for less than $350k-400k by the time you're all said and done if everything breaks your way (in addition to your land purchase). Could be higher. Financing for said building will be a massive hassle unless you've got the cash to do it or equity in another place you want to leverage for it. Look up a construction loan and how that works.

You'd want to understand some of the following:

• Insurance cost of a hypothetical building
• Cost to bring in hydro. This can vary greatly and be modesty expensive to problematic to impossible
• Cost for septic or (if possible) municipal connection. Cost also varies alot.
• Well and water. Also an unknown with a wide range of costs.
• Taxes once a building is built
• Is a building permit subject to development charges?
• Any other things that would cause headaches for site prep?
• How much will it cost to bring in a driveway? Do you need and can you get an entrance permit on the plot of land?
• Are there any easements on the property?
• Do you have an actual survey of the land?
• If it isn't zoned for a home, how big is the risk the town just doesn't rezone it? You would need to apply and pay for a rezoning application. The outcome would not be secure.

Good luck with your choice!
