This wouldn't be hearsay from a neighbor — it would only be after seeing the neighbor log into the icloud account and seeing Apple's tracking system showing it was in the house. Hearsay is when someone says something but you don't see it with your own eyes. If this is indeed a house, not an apartment, I would think that that location accuracy would be high enough that its presence over multiple days would be enough to get a search warrant.
