To answer your question yes its enough but in many cases it might be risky.2. location, room to raise rents, occupancy of property, local laws, type of investment are just a few topics that play a huge part. 

- regional / drivable destination (I've personally rented out a bunch of Airbnbs here)- already established STR laws (while very strict, they have shown to grandfather in permits and haven't proposed a flat out ban that would also retroactively take away permits)- Fredericksburg also fights new hotels just as hard as STRs.

Check the states laws- depending on the strategy, you may not have to register.

Since we are both in Chicago, I would highly advise checking into the landlording laws here. 

Or else reduce enough on price to deal with an eviction from an illegal unit.I don't know Chicago laws, but in NYC if you have an illegal unit, the tenant occupying it seems to have more rights than the owner does and doesn't have to pay rent... 

However, just because I don't agree with it doesn't mean I am in favor of the Government being given additional power to enforce additional laws and restrictions that infringe upon our freedom.

It is just laughable when places have regulations like a homeowner can only have a certain number of STR listings by the law but these big name companies suddenly start with 20 units in the first month.

You need to think about not just the potential income but also the potential problems such as city ordinances, state law, insurance, potential eviction issues, etc.

You didn't say anything about whether the lease or local laws actaully allow you to do this. 

Because FF is not a booking platform, make sure you follow all applicable fair housing laws when talking to potential residents.5.
