That's the point. Rents should stay more or less the same, but now renters won't have to pay a bullshit fee up front.
Landlords can list their units on whatever listing sites/services for like $500 a pop, and renters won't have to pay $5k-$10k to a broker who did basically nothing for them.
Rents will not go up; rents are a function of what the market will bear, not of a landlord's costs.
Right, I doubt it lower prices but it will save people money on the buyer side. I don't know how you would lower prices in NYC other than building even more.
