It is not unusual for expenses to eat up several hundred dollars a month for multiple months in a row, when dealing with old houses.

@Miriam Velazquez  This sounds like a very unusual situation.

Airbnb blocked 11,000 bookings in Arizona last year with 'anti-party' systemVacation rental company Airbnb released how many bookings it blocked in Arizona last year using its "anti-party" system, which blocks renters younger than 25 without a positive rental history from booking homes in their local area.In 2020, the company took the unusual step to prevent bookings under certain circumstances as Airbnb hosts and communities around the country complained about nuisances and violence.

You're betting on uncertain costs and uncertain future.

It sounds too flakey to be real....Trust me that in Miami, this is not so unusual.

Things seem uncertain and the market has cooled considerably because of these rate hikes.”

The market is uncertain but there are growing areas where the risk of an additional 20% decline from already reduced prices is not high.

Not knowing what the amount in question is, its unusual that an agent would risk their career or license for a clients rent.

In short, the more risk or uncertain the properties expenses or income I'd want it to be closer to 20%, if the property has more certainty or easy to analyze expenses then I think a number closer to 10% could still be successful. 

I agree with the article. 2020 & 2021 were unusual years because a lot of people were able to work remotely and wanted to escape urban areas.
