I have been into flying r/c helicopters for some years albeit the enthusiasm has dropped somewhat of late. Drones = aerial photography and are relatively simple to use. If you want to play with drones then fine.. go get one But realise that quality of video or stills really comes down to quality of camera and editing ability.
There are some realities to consider... how often are you going to be re-watching those videos? Would you be just aswel off with a few still images that could be hung as pictures on the wall to show progress? Or both. Meaningful changes in the land don't happen overnight so how often are you going to be shooting repeat vids?
If you have nearby hills then occasional aerial shots from those with a decent camera may give a more consistent diary of change. You might even get just as good to better pics with an old fashioned box kite and a good camera that shoots timed exposures.
What drones excel at is things like checking the gutters and factory roofs for damage or doing promotional vids for rural retreats, golf courses etc Oh, and looking for lost drones.
If you do get one then please check the regs on using them.
I'm on the wrong PC for my full library of pics but this image was taken just with a phone camera from the top of far field a couple of years ago. I don't think a video would say much more:
