Hi! I've had STRs in JT since 2018 (purchased the houses in 2016), and now I'm living here in the hi-desert full-time, so thought it might be helpful to contribute my thoughts...
1) Building a house from scratch, especially in the Joshua Tree area, will probably take much longer than you expected. Whatever your contractor is telling you, you can usually double it. That's been my experience, at least. Who knows, the recession might come and go by the time you're ready to rent.
2) Joshua Tree is definitely over-saturated with STRs at this point. We launched ours in 2018, and in 2019, Airdna listed us as the #1 most profitable STR in Yucca Valley. 2020 and 2021 were AMAZING, but this year, our gross is about 20% less than it was in 2019. And we've put a lot more money into the houses just to keep up with all the new STRs. The culprit for the over-saturation is all the press Joshua Tree has received since covid. And I think us being on Airdna's "top places to invest" list just after the pandemic has been a big contributor to the over-saturation, as well. So you definitely want to make sure your house stands out from the competition with its architecture, amenities, decor, location, etc. I would suggest taking the time to do a deep dive into who your target market is and who your competitors are, and then putting a lot of thought into how to use that info to your advantage.
3) You said you're near Joshua Tree, so not sure whether you're in San Bernardino County or the Town of Yucca Valley, but I hear SB County is looking to put a cap on the total number of STR permits they issue starting March 2023. I hope that doesn't happen, but just something to be aware of. And Yucca already has a cap in place.
4) When deciding whether this will be a good investment for you, it's important to take all the factors into consideration, not just financial. When we decided to invest in the hi-desert, we were living in LA at the time, so we knew we could take our own personal vacations there when a house wasn't rented, and we could use it to celebrate our birthdays and holidays, and one day we could potentially retire there. So in the case of a recession, as long as the STRs are still covering the mortgage and expenses, it's still a good investment for us. For an outside investor who is strictly looking for the financial gain of it all, I'm not sure the ROI makes sense anymore unless you have a SUPER special property or location. But only you can determine whether this will be a good long-term investment for yourself.
4) When it comes to STR performance, I personally don't believe it makes sense to classify the pandemic/post-pandemic as a typical recession and compare it to the recession that everyone's predicting will come in 2023. Following the 2020 lockdown, people were itching to get out of their homes, but they couldn't fly and didn't want to stay in hotels, so they all fled from LA to the nearest Airbnb destination, which was Joshua Tree. In that sense, 2020 and 2021 were anomalies. If we have a recession during a time where there's no social distancing, where people aren't locked inside their homes, hotels aren't a scary place to be, and airports aren't shut down...I doubt we see the same surge in STR bookings. But I also agree that this industry is reasonably recession-proof because those who normally travel out of the country for vacations will probably just do their vacations within the US to save costs.
And that's my two cents!
