Would love something like this to kill (or at least severely maim) the broker industry in NYC. 0 value added at the cost of 10-15% of yearly rent.
The assumption that software can solve this problem is simply wrong. It's the regulation change that needs to happen if you don't want that renter pay the broker "services". For example, a new law in Germany to apply the "who hires pays" principle for brokers in the renting market basically made the renting "broker fee free" for renters. Previously, the landlords would hire a broker that needed to be paid by the rent…
It can't be quite this simple. If your renter is paying $X to you plus $Y to your broker, then their willingness to pay for the apartment was at least $X+Y, and you're leaving at least $Y on the table. In theory there should be a lot of market pressure to shrink Y. So the question becomes, what transaction costs are getting in the way of that? Or maybe, is the $Y actually buying something that's of value to the landlord?
