What if, upon an imminent snowstorm, Home Depot began charging $200 for a snow shovel, just because they could? 

Quote from @Amol Kulkarni: Has anyone used Homeriver Group Property Management in Jax and Citrus Spring.

This isn't including a management since they currently do it themselves.

I'm a property manager, and I also buy/sell property.

That makes the investing and property management a LOT easier.  

Though I have purchased some with a mix where 330+ days a year, people parked in the driveway and the street except when there were snow bans, but there was enough room to fit everyone in the driveway/parking lot, and that was a hassle to deal with some days. 

Do it very intentionally, not just for the sake of scaling up, but to get better quality or easier to manage properties that will replace lower quality or harder properties. 

The truth is, a good host will spend time managing each rental.

And who is taking care of the landscaping/snow removal? 

Hire a property management company who will manage it for you.
