They like the place and don't have to move so you can get a premium. 

While we’re on the subject of marketing, how do you like Premium membership with BP?

If you think you'll hold onto it for the long haul (min. 10+ years), then sure, you can fare alright if you buy something where the numbers make sense today.Personally, I wouldn't touch anything today that was turn-key, especially on the MLS, selling at a premium.

When those properties come up for sale, there is a definite price premium placed on the nonconforming use certificate.Please feel free to reach out with any other questions.

There is a cost, but you will sleep better at night and your insurance premium should be reduced for it.   

As a manufacturer, trader, or supplier, if you had wood on the ground you could sell for a PREMIUM.

Edit to add- would it be wise to have them put a lien on my other rental properties which I already own? 

They say it's due to the uncertainty in the market (Many lenders say it's because they make money on the yield spread premium and wanted a bigger piece of the pie.)

These products allow the        tenant the option to pay a small monthly insurance premium to the insurer in lieu of a lump-sum full security deposit            payment at move-in.

The nice thing about condos is that if you can get one unit up and running successfully, you can buy a bunch more units in the same building and then you benefit greatly from economies of scale.You can have multiple Airbnb listings, some are solo listings and some advertise that they can book a bunch of your condos together, of course paying a premium price for that.
