When I started my business in 2015, real estate work was on the top of my list for income. I got over that real quick. Most real estate firms on the Olympic Peninsula (at least the larger ones) have a least one or two sales people that own drones. They use these in-house folks to do much of the aerial work for them these days. I think a lot of them are not commercially licensed, but I'm not going to call them on it. Nor do most of them actually have editing experience and some of their videos you can tell right away.
I have flown about a half dozen high end homes and properties on the peninsula. I get called by many real estate folks, but when I tell them my prices, I don't get many call backs. And that doesn't bother me in the least. I fly for government, corporate, a local public access TV station and tribal entities and have plenty of work.
My advice to anyone entering this segment: Don't put all your eggs in one basket! Diversify! Don't just count on the real estate market for your bread and butter. You'll go broke if you do!
I charge $100 an hour for flying, with a 2 hour minimum, if I'm there 10 minutes or two hours ... it's $200. I charge $50 for editing. A typical 1.5 to 2 minute real estate video is around $400. More if I do still interior photography along with the aerials.
Here is my last real estate video I did this summer at the mouth of the Elwha river west of Port Angeles, WA. It was a combination aerial and ground based. $600. They wanted no music, titles, or voice-over.
