Rural comp analysis?

[Jake LaRoche]

looking to get into my first house hack but i wanna get a good deal with a medium rehab so i may get some equity to roll into my first BRRRR. how can i make accurate comps in areas where houses are very different and spread apart I.E. Hudson Valley. i know i can go to a relator but is it reasonable to go to one for every potential deal that comes across my desk?
