Houses don't necessarily need to appear for everyone at the same time ether. If someone appears to be pumping, the ten minute wait could increase by increments of a couple minuets to further reduce the effectiveness. This staggering the would also encourage other players to take the 2K before the offending individual, which I believe may be enough to render pumping ineffective all together, especially if the in game community is fairly active. Unfortunately, depending on the design of the game, this method may not be practical to implement, especially in comparison to the simple ten minute timer.

On a side note, the timer may also improve the games accessibility, by giving new players a chance to understand the structure of the game, before their house is immediately robed, though this is likely less of a concern, or may even run against the design goals.
