It looks nice, though the design is so smooth and monochromatic I wonder if people would find it more appealing if there were some generic housing photos as illustrations. I'd also suggest using screenshots to give people a better idea what to expect. It may be worth thinking about a more slimmed-down sign-up process that lowers the barrier of opening a test account and enables people to play with the app right away. It's clear a lot of effort has gone into this, keep it up!
