Although this sounds like a great plan, when they mention training their just like other lead sources.

If anyone stays beyond 10:30 AM I was authorized to call 9-1-1 and someone would be there to arrest Tresspassers.I actually gave them til 7:30 PM the first night before locking the door, and then I even came early to open the place up at 7:30.

Excessive complaints or three violations in three years could lead to losing the ability to operate​.Impact on Neighborhoods: Non-owner-occupied STRs (Type 2) may cause friction in residential neighborhoods, as they often function like businesses, which can disrupt the local community atmosphere.Recent Regulations (2024 Updates):1) STR operators must obtain a permit for either Type 1 or Type 2 properties, depending on whether the owner lives on-site.2) Platforms like Airbnb are required to remove any listings that lack a valid permit.3) New noise and occupancy regulations apply, with stricter enforcement through permit revocations and finesThese regulations are part of the city's efforts to balance the benefits of STRs with the preservation of neighborhood quality and local safety standards.4o

First, if you're getting $75/month in CF ($9k/yr), and you put $110k in cash in, your CoCR is 9%, not 9.5%.Second, and this is the number that counts (% mean nothing, and will lead you to illusions), if you're getting $9k in cash back/year, and you put in $100k in cash, it will take you (if all goes perfect) over 11 years to recover your cost (cash). 

So you need about 50 leads to convert to 1 transaction.
