Even if you're not looking to move into a new place, spending a day visiting open houses can be an exciting date activity. How else can you tour strangers' homes, take on a house-hunting persona, and bond over awful furniture? Visit a mix of places that are practical and totally out of your budget to get the full, fun experience. The best part: it's absolutely free. And who knows? Even if you don't live together now, it might be good practice for the future.
