Most important thing in new bee place is that there are no other beekeepers. You can find it out if you see how much bees are in flowers.
Turnip rape is importand honey flower. Fireweed is as important. When I find the pasture, where is both main flowers, I go to the owner and ask permission to bring hives.
I live in a flat in the capital city, but I have bought a summer cottage from eastern Finland, and sorry to say, beekeeping was the most important thing when I choosed the cottage.
I have carried my bees to outer pastures 40 years. It is not easy to find good places. When you put hives in several places, you can see that yield may be 2-3 bigger in one place than in another, or even 5 times.
