Keeping listings up to date is one of the issues they need to fix but I don't think it's impossible. I think it's a teething problem rather than a problem with the system.

I had a similar experience myself - applying for places and finding them unavailable - so now that I'm on the other end putting my place up for lease I'm sure to respond quickly and keep my listing up to date.

I've had a couple of ideas on how they could fix this problem with changes to the UX and considering I'm no designer I'm sure they have even better ideas and will fix it soon. I hope so anyway.
