They're going to opt for the b&e when no one is home. Natasha would scout the place and the immediate surrounding area as much as possible beforehand, just to try and limit the amount of surprises they might have and to be as aware as possible of their surroundings.

Infiltration is pretty standard fare for her but they also have Lucifer's ability of Knock as an alternative if they need it. Natasha has also been learning/practicing Illusion magic from Stephen in case an emergency demands some sort of diversion.

They'd be focused on finding anything that stands out as odd or might coincide with other investigations they've been dealing with/keeping tabs on. Strange transactions. Maybe mentions of Josselyn? Nat in particular is aware of the rotted wood found in the FC shipments and keeping that in mind as well.
