The California-based company, founded by Dan Laufer and Byron Singh, hires local experts such as former property managers to tour apartment buildings and rate and review them on RentLingo.com. With most online apartment reviews, it's impossible to know if you're getting the complete, unbiased truth or if you're being influenced by one or more angry individuals with an axe to grind. The company sets out to provide a comprehensive listing of reviews for each market in which it operates. Visitors to the site can search apartments by ZIP code, price range, and specs such as the number of bedrooms and baths and whether pets are allowed. The company makes money by partnering with other listing sites such as Move and Apartment Finder.
