It's weird right? The rest of the world, the people who will be paying you money or helping you solve your problem, don't always operate in the same closed off world of email-only communication. In my work experience : Phone calls or in-person meetings = $$. Email only = lots of emails. So, in this case - I'd compile a list of realtors and/or letting agencies. Then, call them up and ask them about their pain points. Not only will you get REAL and valuable info, but you'll be making potential connections. (call them up next week and say, "hey, remember that product I was making to help you? well - I did it, you should check it out") A room full of programmers will likely never have the answers that you are looking for (in this case).
