Places will be booming for the next couple of years due to pent up demand for travel.

I tried the traveling nurse route for a bit when I had a couple airbnb's.

Time travel back to the past!!

You’ll also be more likely to recognize situations in which you might overspend; special occasion spending like travel, birthdays, graduations or anniversaries, for example.In other words, learning how to manage debt comfortably and when to pause before borrowing can help you enjoy the opportunities that good debt can provide while avoiding bad debt pitfalls.

You will learn a ton of stuff as you travel this one. 

My husband and I are closing on a new build townhouse in the next few weeks and within the next few months are hoping to househack it by hosting travel nurses (we have checked our HOA bylaws and there is nothing in the document restricting it).

I traveled on some European trains when I was in my late 20's and it was a great experience.  

Also, many do not want to travel into less desirable neighborhoods. 

I also wonder if some of the travel nursing agencies might be a good resource for you to try.

In regards to pure vacation rental I don’t have experience but I run small 1bd airbnb STRs in my city that targets travelers and workers - not really vacationers.
