Few days ago I was with a client in Niles, IL and I had an app for that.
While I was showing a home, my client saw a sign of a home for sale across the street and wondered: "How much is that home?" I had that cool moment with a big smile: " It's this much, with that many rooms, bathrooms .... check the pics with app for this. This particular app is so cool. It shows all homes on the market from your spot. The closest one first with all the info you need. I felt like a cowboy in an old western movie. I pullled that phone in a blink of an eye and opened an app for real estate in a sec.
Sure I have a Twitter and Facebook app and few other ones.
These are my two virtual cents on the app for real estate. While I was writing this blog post I found more real estate apps ... that have to be tested by yours trully :)
