STR's are the most management intensive way to produce cash flow on a property and Tokyo is 9 hours ahead. 

You might start by finding a property management company that specializes in MTRs and ask them if they know of any Realtors who understand this niche.

I self manage and like having full control over the whole thing.

I expect I way over estimated the number of STRs and Hotel rooms and occupancy is closer to 75% to 90% for 2024 depending on the economy, but mostly on the product/service/location being offered by each owner/property and the manager (including self) ability to actually be a manager.

I live far away from this house, thinking about getting a property manager.

Do you self manage?

Once the 5 years runs out you'll have used up your existing available depreciation but you still get to write off other expenses such as maintenance, property management, legal fees, etc.

So, in this way I manage the portfolio has a business instead of managing each property as its own separate business.

The Lead investor is the one finding the property, setting up management, raising money, managing repairs and upgrades, dealing with insurance, making distributions to investors and completing all the tax documents for the investors.
