I have owned in both areas with no issues and good revenue. 

If you have commercial experience and are an excellent asset manager (managing the property manager, driving revenue, reducing expenses,  managing GCs)You wont just provide value to a sponsorYou will be highly sought-after after by sponsorship groups.The ones worth their salt know how incredibly valuable a strong asset manager is (and how much work it takes)So if you can bring that skillset, I have a feeling it won't take long for you to find a sponsorship team. 

Would it make a nice mid term rental if I need a revenue boost?

They prevent bedbugs from entering or escaping mattresses.Routine Inspections: Regularly check mattresses, bed frames, and furniture for signs of bedbugs (small black spots, eggs, or live bugs).Furniture Choice: Choose furniture with metal or plastic legs instead of wood, as bedbugs are less likely to infest non-porous surfaces.Bedbug Traps: Place bedbug traps under bedposts and other furniture legs to catch any potential bedbugs before they become a problem.Professional Cleaning: Schedule routine deep cleans between guest stays, and if you ever suspect bedbugs, hire a pest control professional immediately.Clear Guidelines: Educate your cleaning staff on how to spot bedbugs early, and encourage them to report any signs immediately.These steps will help you set up a smooth, well-managed STR that’s ready to generate revenue while maintaining a good relationship with your LTR tenants.

Have a few properties fully paid off, earmark 50% of the revenue as future capex repairs, other 50% has FCF.

Also, it depends how good of a deal you get and how good an operator (or the one you work with) are.Assuming you buy the "right" property in the "right" place overseas, you'd typically have a higher unlevered ROI overseas because a) a like-kind property would be cheaper and b) the (high) season could be longer and therefore the revenue higher.The US used to have the advantage of the financing (availability + interest rate).

There are STR specific DSCR loans that account for the previous revenue if you are buying one that has been going already.Read Avery Carl's STR book from BP and also follow Bill Faeth, Kenny Bedwell, Taylor Jones to start with to get an idea of what is happening in STR right now.

Here's why:With a DSCR (Debt Service Coverage Ratio) loan, you can leverage the rental income from the property—like the $4,800/month rental revenue—instead of relying on the seller's personal credit or income.

Costs were low and revenue was high. 

SFH's can carry more risk as you can quickly lose 100% of your revenue if a tenant stops paying, but they also generally come with more tenant stability.
