First of all! Have you won the lottery? 😊
I think it is not a good idea to have lots of listings in different cities.
It will be hard do manage. You will have to hire some cohost on each city.
If you have 10 listings in 10 different cities you will have to deal with 10 cohost.
You know... difficult to find the right person to do this job... imagine having to deal with 10 cohosts.
So, if you are really minded, I suggest to buy listing in only one city. Pick some city that has tourists and visitors all year long ... kind of San Francisco, New York... os some small city in the south of California, near the beach where there are sun and pleasurable climate throughout the year.
During the pandemic it is said it is not the right time to invest! It can be questionable. Maybe you can find some properties at reasonable prices.
If I had some spare money, I would buy real estates.
Still, during the pandemic, it is not a good idea to offer too short stays and have guests checking in and checking out frequently.
If you offer at least 14 or 30 nights stays, maybe it will be less profitable, but you still have some income. When the pandemic finishes, you will be ready to go "at full steam".
Whatever is your decision, I wish you success !
