Unless your going to be there, or hire a property manager (which in some countries is actually law, like Canada if you live outside Canada LOL) , just don't .
Driving 2.5hrs, taking the boat ( you borrowed, your is at the water access cottage) 30 mins down the lake, listening to the moaning there has been no water pressure all day and you literally flip a breaker that they swear they tried 6 times. I could not collect enough rent for that nonsense.
I'd be looking at a piece of property somewhere inside a 20-30 minute drive from my house and making it a "unique experience" type setup. My experience thus far on AirBNB is that the "unique experience" category is not only simple, but in high demand.
My daughter used to work at a place on the outskirts of Toronto that had a "tiny home" built inside a Sea Can tucked into the edge of a forested area. It's on AirBNB as a "unique stay" for $100 a night or something in that range and it's booked almost every single night - $3000/month. Even if it only averaged 50% occupancy, $1500/month for something that likely cost less than $10K to put together, well, not too shabby. No bathroom (just a clean porta potty), no kitchen or cooking facilities at all, just a cool little seacan home with a comfy bed, a seating area, a few lights and a single plug for charging electronics, and a few muskoka chairs out front facing the woods. And people eat it up.
Not saying that a sea can is what I'm aiming for, I'd probably want something different..... What I have in my mind is buying a chunk of property somewhere in the woods (again, the "outdoor experience" segment is hot), have a rustic (but not fancy) cabin of some sort constructed (honestly, the more "rustic" it is, the more in demand it seems to be, and you can keep pricing lower which helps a lot as well) and then put up a few yurts on the property as well as that's another experience that seems to be constantly booked at every place that has them, so long as they're priced properly.
On the topic of pricing, that's where many people on AirBNB go wrong. Yurts (for one example) are super popular under the Glamping/Experience category, but some people seem to think they're worth $300+/night and their bookings suffer as a result. But anything in the $100-ish category....almost always booked solid. Even in the winter (fireplace solves the heat issue) they're averaging 20-50% booked. Even if they sit empty and the cabin alone carries most of the mortgage on the property (and yes, we're financially able to carry things even if there's 100% vacancy), with the yurts being gravy in the summer, there's profit to be made.
In the gravy months in the summer we roll 100% of the income against the mortgage to pay it down faster. In the winter, we carry it ourselves if needed.
KOA style camper cabin with no running water or facilities
bring your own bedding.
Solar lighting, if they go out don't call me, wait for the sun to come up.
Hunting cabins are very seasonal.
This.
And cabins not need be seasonal. The place we're going to in March I mentioned earlier in the thread is completely off grid. Composting toilet, some limited solar electricity, and a fireplace.
$220/night. Booked about 28 out of every 30 days within a 1 month period from what I've been observing, with the only empty nights being awkward weekday nights where people booked a 4 or 5 day weekend and there was an orphaned day in the middle of the week...and even then I see those snapped up sometimes last minute. This one is booked fairly solid through to March at this point and approaches 100% solid all summer long. Like I said, this is one we've been watching for quite some time.
