I am hoping to find distressed properties that I can buy with all cash for BRRRR and am also open to any sort of partnership.

What do fire people do if they are not sure where they want to retire in 10-20 yrs?

You need a great project manager (if that is yourself, you need to stay on top of all the people)4.

Or are people typically looking to rent bigger units? 

Things like septic pumps burning out, steam room dying, guests catching the grill on fire and leaving burn marks on the hardi siding, emergency bug treatment, above ground pool which is ridiculously hard to manage in our heat & having no time to deal with it if it starts to go, laundry & drying time for all the towels and linens, etc, etc.There are plenty of things we can and will get better at, but I'm prioritizing the stress level of my people as well as the very near disasters we've narrowly avoided, over the little bit of extra revenue we'd generate.

Im looking to buy a single-family home in Jupiter Florida and would like to rent it out on Airbnb (open to LTR).

If the property has continued to appreciate, perhaps him buying you out at market value makes the most sense, then take the cash and roll into a new property.It sounds like you would like him to pick up another $500/month (pay you the $1,000/mo rent + pay 50% of the remaining mortgage split). 

For 99.9999% of people, unfortunately the answer is no. 

Learn how to buy properties to flip or even buy and hold on paper to gain some expertise. 

Unless you are in a vacation area, I would never buy a STR that does not work as a LTR.Regarding another pandemic, we have one like every 100 years, so I am playing the odds that we are not going to have another covid lockdown situation anytime soon.
