If the house has a specific 70s feature (like a conversation pit or avocado green tile), mention it! People love to comment on nostalgia.
Use a "then vs. now" split if you have old photos of the house, or a shot of you holding the oversized, old-school keys.
⚠️ The "Surprises": You quickly learn that "vintage charm" is sometimes code for "colorful plumbing" or "creative electrical wiring."⚠️ The Projects: My weekend plans now officially consist of wandering the aisles of the hardware store.
