They need landlords to stick to the numbers they pass on, in order that those numbers remain valuable to all of their other landlord clients.

Suppose that you're a big landlord in some area, such that your submitted prices can affect rents for that property type across the area. You might be tempted to submit high prices, wait for your competitors to follow suit, and then reduce your actual rents to undercut them. They (the competitors) naturally wouldn't be happy with this. So RealPage has to be able to show people that they know their numbers are the actual ones.
