Yeah, I want to do this as well. When Tesla announced the gigafactory in Reno, I really wanted to pool together with others to buy an apartment complex or something.
I'd say not really. The graph doesn't seem to be linkable, but if you add "Las Vegas" as a comparator, both Fernley and Vegas moved in lockstep. Vegas is way too far away to have its prices affected by the Gigafactory, so I'd say that there was no discernible effect. Or, at least, a very modest effect.
