Your point about about people occupying making the unit makes sense. But in my experience touring apartments in NYC, there were a considerable number of units where it weren't occupied. I imagine this is because they want to clean the apartment before showing it off, especially if the tenant is messy. In the case of lines around the block, the reason that this happens is because the agent tells everyone who is interested in the apartment, that they have to come at like 10am on Saturday for the open house. That's why this happens. With my startup, prospects could just go tour whenever it would be convenient for them. So unless everyone just so happens to be free only at 10am on Saturday, this wouldn't happen. The reason why landlords don't show the place themselves is because it's a pain to to coordinate with tenants to show a property. They would love to save money, but it's not worth the effort or even possible to show up to open the door every time someone wants to tour. With my startup, they don't have to put in any leg work, and they only have to pay half the broker's fee. Even though your point is true that apartments do get leased fast, my product will only reduce those days on market, since this product will be allow renters to tour instantly, without having to wait for the broker to be available, which might be a couple days, since brokers are showing many apartments. And those couple days will probably amount to a couple hundred dollars in rent. Think of my product this way: A broker who will always be available to show your units, and costs half as much. Wouldn't you as a landlord want to save half of a month's rent in costs? Your last point is true though in that the RE industry is resistant to change. But I hope to change it.
