Mid Term Rental Market/Pocket

[Hadar Giladi]

Hi everyone! 
I'm currently conducting research on the mid-term rental market and I'm quite interested in it. I'm searching for a wide range of information sources, but I'm still struggling to fully comprehend how to identify a suitable market and a specific pocket within that market. I would greatly appreciate any ideas or guidance you can provide to help me choose a market and begin my venture.
Thank you in advance for your assistance!
