This past weekend I was in a condo building here in Toronto with large signs in the elevator saying, "No Short-Term Rentals Including Airbnb Are Permitted. Trespassers Will be Prosecuted." It was the first time I had seen anything like this, but it immediately signaled to me that the building must be having a problem with short-term rentals. Why else would you deface the elevators? There are some buildings that allow short-term rentals, but most don't.

However, over the last few years we have started to see purpose-built short-term rental buildings. In some cases, existing apartments buildings were "converted", as was the case with Niido's two properties in Nashville and Orlando. Here tenants in the building can rent both unfurnished and furnished apartments and then rent them out on Airbnb up to a maximum of 180 days per year. To date, I think these are the only two properties to use the "Powered by Airbnb" moniker, but more are on the way.

The developer behind Niido -- Newgard Development Group -- recently launched a new Powered by Airbnb brand called, Natiivo. This one looks to be focused on for sale product, with two upcoming projects in Austin and Miami. Both projects will have hotel licenses in order to avoid any regulatory risk going forward. But this makes me wonder how materially different this model is from the condo-hotels we're already familiar with.

For landlords and developers, the goal is obviously to maximize rents and prices. Allowing (or explicitly encouraging) residents to rent out their place and earn some extra cash, should help with that. And given the way I started this post, we also know there's a desire to do this, particularly in places with strong tourist demand like in Nashville and Miami. But the reviews are mixed. Not everyone wants to live in a hotel. But then again, not everyone wants to co-live. To each their own.

Fred Wilson made an interesting remark in his recent post about the current "IPO bonanza" that is taking place in the tech space. He is, of course, talking about the recent IPO of Lyft, the recent S-1 filings from Pinterest and others, and the expected filings from Uber, Airbnb, and so on.

After listing the benefits of going public, he went on to say that this bonanza will surely also mean that it is going to become even more unaffordable in the Bay Area. Part of this is perhaps self-serving, since he operates a VC firm out of NYC. (Take your money and move to NYC.)

But the data suggests that there is truth to this.

When Twitter when public in 2013, it was estimated that it created some 1,600 millionaires. This is great for the local startup ecosystem as many of these beneficiaries could go on to found their own companies and create a whole new batch of jobs. The money gets recycled.

But what does it do to the local housing market -- especially a supply-constrained one like that of the Bay Area where it is difficult to build?
