I just had a nasty surprise and got 1/3 less income from my vacation rental than I thought.
When I listd my week for rent I made the mistake of using AirBnB's recommended market price - it end ed up begin less than half of what I could have gotten. To add insult they told me the amount I would be getting upon checkin but 1/3 less arrived in my account. That's very misleading.
AirBnb is quite deceptive in that it doesn't disclose up front that they will be taking 30% off the top of any rental for US Tax Withholding. This is double taxing for foreigners as we need to declare that income in our home country and pay tax on it.
So be forewarned - if you are a foreigner but are renting property that is in the US you are going to lose 30% off the top. Price your unit accordingly or better still use VRBO or other sources who do not withhold.
