I am setting up an airbnb and still figuring out which channel manager I will use and the feasibility.

Below is the median net worth of Americans by age according to a recent "Survey of Consumer Finances" conducted by the Federal Reserve.Under 35: $13,90035-44: $91,30045-54: $168,60055-64: $212,50065-74: $266,40075 and over: $254,800At this stage in your life, if you are ahead of the average American, what do you attribute your "success" to?

I would go with a company who has multiple properties under management (ideally over 500 to really get the benefits a scale, think cheaper maintenance visits, experience placing tenants, lots of investor experience, ability to find deals within the brokerage, massive marketing channels for properties, systems in place to handle problems, experience handling a massive amount of problems, discounts for bringing multiple properties to manage).Also, make sure your property manager is motivated, experienced, and growing! 

No matter how good your manager is, numbers can get keyed incorrectly.

I am a landlord and property manager... I

And why I said fund manager is dumb ?

I feel like starting with the golf simulator makes more sense and will help not only increasing nightly booking rates but also with occupancy as it is a unique attribute. 

Next, I would look at your state's laws, they may limit how you can bill tenants back for usage not specifically attributable to them.

If a TK provider or even a broker/property manager is only pitching you on the good about a marketplace and not explaining the risks associated with the marketplace, that would be a major red flag. 

Unfortunately, because I didn't have a good contractor or property manager, I ended up losing money for the first two years before turning them into a success.
