I think Real Estate is my favorite thing. Well, I know it is, that's what got me into photography and drones. I agree with you completely.
The problem I had was that realtors around here didn't want to pay what I thought was the minimum of fair. I wanted $250 flat fee for coming within my range and doing pretty much anything they wanted, go home and edit and then upload.
The editing was what was getting me. Even the trip and time is probably worth that, but the editing was a ton of time. Tons of fun though. There is just something I really like about shooting real estate. I love shooting any sort of sales shot really, lol.
