Asking about the SW suburbs specifically, in the land of long sidewalks and big actual parking lots. 

It is what is left after snow removal, cutting the grass, utilities, tenant issues, parking lot issues, property taxes, mortgage payment, etc. that make a difference.

I own 4 two/three flats bought between 2013 and 2020 in Forest Park, Illinois, at low interest rates and prices in 200000's  They cash flow nicely and prices have increased a lot. 

If I was buying south or southwest of Asheville right now I might be trying to get very close to one of our great new downhill mountain bike parks, meaning Ride Kanuga in Hendersonville or Ride Rock Creek in Zirconia.

That might include things like adding units, converting commercial space to residential, or finding ways to boost income (like adding parking).The key is recognizing opportunities while walking the property, and that takes experience.

FL has a ridiculous number of low-value properties, everything from essentially campers on 55+ lots to MH parks everywhere to run-down shacks in much of the rural areas, all of which is going to drag down the average premium.

Increased revenue and decreased parking demand allowed us to carry income-restricted units as well.We originally planned on spinning it out into a brand, but we never had the bandwidth to do so.Our largest hurdle has been education as most of our tenants are coming in to rent traditional units.Investors did not love it. 

.-- The biggest indicator of turning public sentiment was just last month, in December, when voters in Woodland Park approved a ban on vacation rentals that also appears to NOT grandfather in existing licensed properties. 

Recently decided, to invest in a mobile home park but sold at a loss.

Most people who complain about Airdna overestimating their revenue think you can just list your house on Airbnb and profits will pour in (South Park understood this fallacy best).
