What is the incentive for someone to leave a review? Given that each person only has a handful of places they can review, you won't have serial reviewers like on other review sites.
I don’t know about where you live or what it’s like in the states where this site is presumably targeted but in Australia people would have ample opportunity to be serial reviewers.
The incentive is having some power over the landlord: treat me badly, you get a bad review. No idea why someone would write a good review, though. But bad reviews are more important. Landlords already have the benefit of the doubt.
