I love Mexico and numerous other international destinations, but as an investment, I'd rather have my investments closer to home where I feel a little more control and comfort with the local government. 

What is your goal, the destination, is $5,000 mntly an endpoint or a way-point?

I learned a lot about the obstacles in getting PPE to the right destinations.

Then totally pick your vacation destination based on your emotions, without the extra burden of having to manage it when you're not there, and having to go back again next year even if you want to go somewhere else.That said, if nobody goes on vacation this year we may see a big sale in vacation rentals. 

Strangely enough, I was cruising Pinterest and was reading something from cashflow diaries.

You're certainly right to say it is not a huge Airbnb destination (except for those big weekends like Little 5, homecoming, etc...) , but the school accepts more people every year, so if you could ever see yourself investing in short-term student rental properties then that's the place to be! 

Houston has become a financial destination location, coming solely for employment and then eventually migrating back to where they originated from: As long as there are jobs - people will be here.

As someone who is a landlord and a AirBNB host, let me say "Don't freak out" Yes the tenant should have asked if they could run your property as an AirBNB destination, many people are doing just this, your tenant skipped the "Ask first" part.  

I've lived in Yuma my entire life, the number one winter visitors destination, I have a list of condos, town homes, and sfh, all within got below your range, 40k to 189k of all different sizes and finishes.

I imagine there is probably a bit higher vacancy, but still a year round destination especially if you have a pool.
