I checked it on my phone. Overall a well done design for mobile. I'd recommend scaling down (or eliminating) your photo on smaller screens. It fills up almost the whole screen on my phone when scrolling down the page.
The property search completely froze my phone, so that's a pretty big deal breaker.
I also agree with Ken that having the entire site lock up if you don't create an account is going to make me close the page long before I sign up for anything. My information is worth a hell of a lot more than just the ability to look at a couple of photos, especially when those photos are freely available on the MLS site. Show me the value of creating an account before asking me to create an account (and even then, it should be optional unless there is something proprietary on your site that is valuable enough to protect).
Turn up the good, turn down the suck!
