Also, if Reiner and Bertolt knew about it, don't you think Zeke would have them rip up every basement in Shiganshina for fear of the humans learning something? I can see Zeke making them do that, even just as a precaution. You bring up a very interesting point but even though it kind of sounds like a plothole... I don't think they actually did that... because you know, Bertolt and Reiner absolutely don't know which house was Eren's. I mean, I guess Eren kind of gave them a hint because he told Bertolt (when they're in the trees after Eren is kidnapped after fighting Reiner) that a piece of the gate that Bertolt broke fell on his house. For all intents and purposes that could describe many houses in Shiganshina but it does narrow the list of possible places to look.

One thing though, if Bertolt and Reiner tore apart Shiganshina looking for basements, the SC probably would have noticed that on the way to the outer gate but no such mention is made so I'm just going to assume that they didn't do that until the time comes.
