@Shiloh Lundahl of course we don't mind you participating into the conversation and get your insights. It's not "our" conversation and I personally love your insights, whether I agree with them or not.
You know I think you've created your own mix of lifestyle/investment purchase. It works for you but one of the most important factors is that you find willing investors to participate and not everybody can do that.
I personally wouldn't invest that way either because I believe that, by trying to mix lifestyle and investment, you neither get a the best lifestyle property nor the best investment. I rather buy one of each and keep them separate.
If I want to own in Costa Rica for lifestyle purposes, I'd want to have my own property. This way, I can do what I want with it, decorate it the way I want, use it when I want and sell it when I want. None of your investors can singlehandedly exert any control on the asset they've invested in. If I mainly want to vacation in Costa Rica and stay in a nice place, I rather make more money by investing elsewhere and rent a different villa every year, which is much more exciting from a lifestyle point of view, as I'll have variety. For me, the only interest in going to the same place over and over is to own the place. Of course, this is just my opinion but I bet I'm not alone..
If I'm an investor, I think the returns you're able to achieve in Costa Rica are higher than normal because you focus on these large properties and, as @Martin D. mentioned, prices in that country are too high and returns too low. So, if your investors absolutely want to invest in Costa Rica and maybe be able to tell others that they're (part-)owner in a beautiful Costa Rican property, it might make sense for them to invest alongside you.
However, as an investor, all that matters to me are figures and there and I don't have to own properties in Costa Rica. Like Martin mentioned, I can buy my own property in other foreign countries and make significantly higher returns (which, incidentally, is what I've been doing).
So with the same amount of money that I could invest in a shared villa, I do more profitable investments, make more money and then buy my own property in Costa Rica with the extra money I'll have made and it can be a pure lifestyle purchase.
This being said, if you put together a group of like-minded people who can put some money aside, decide to purchase a property together, don't really care about the return and love Costa Rica (otherwise you could do the same somewhere else), I agree that what you do can be a lot of fun!
@Martin D., there are a lot of places where you'd make like a bandit if you invested before the pandemic boom. I know people who've invested in Bali too but I'm staying away given the property ownership situation. Not worth the risk in my opinion. Money always go where it's treated best. I'll never invest in a country in which I'm treated differently just because I'm a foreigner. Think about what would happen if you ever have to face a lawsuit in such country against a local. Your chances of winning are close to zero.
