Aerial photography and videos are just one potential part of a photography package, and it only makes sense with a minority of properties. Who is making the hiring decision in most cases? The Real Estate Agent. Do they already have a relationship with a photographer or are a DIY agent, yes. Do they see the value in aerials? Maybe not.
You can get an entire home (25 photos inside and out) professionally photographed where they use expensive wide angle lenses that cost as much as your drone, and do post-production to make it look really really good, for..... $150! That's because they can be in and out in under an hour.
Is the agent going to want to spend an additional 200% just for some aerials? In most cases and most homes, no (unless it's only $50 which in my opinion that price is a crock.) Is the agent going to want to have to schedule two appointments, one with the Drone guys and one with the Photographer? No. So in other words, "GOOD LUCK!"
I contacted some companies in my area, told them I wanted the whole enchillada, aerial photos/video, interior video walkthrough, and interior/exterior photos comparable to the best Real Estate photographers out there. 3 of the 6 responses said $200. Two were $250 and one was $350.
Let's estimate what might be an "average" job cost for say a 2,500 sq ft 4-bedroom house.
Discussing job with client, putting together contract, planning the shoot/flight, scheduling, etc. - 0.5 hr
Travel time 1 hr total. Let's assume you have other jobs in the area. In reality for most people that don't have multiple jobs in the same area, and you live in a city with lots of congestion, 1 hour could be pretty low.
Aerial shoot (unpack, checklist, flight, pack up) - 1 hr
Interior (unpack, staging/lighting adjustments, photo/video walk through shoot, pack up) - 1.5 hours
Post Production of aerial video, interior walkthrough, and 25 still photos - 2 hours minimum I would say
Delivery of finished product and discussion with client, billing - 30 min
Total time = 6.5 hours @ $250 a job = $38/hour *GROSS* revenue. Now subtract all your overhead costs like depreciation of all your equipment, automobile operation costs, business expenses like utilities, advertising, insurance, yada yada. Maybe net $20/hr which is about the equivalent of a $20K a year salary IF you did it 8 hours a day 5 days a week 50 weeks a year.
In my opinion, those are prices from people involved in a hobby, not a business. If there are enough hobbyist willing to charge next to nothing, it will never be worthwhile as a business to pay the bills.
