You don't need to be a billionaire to enjoy WA States most expensive town. Hop in your car and take a leisurely cruise through its winding lanes. Admire the impeccably manicured hedges, grand entryways, and waterfront views.
Rent this Mercer Island getaway from Airbnb and you get your own waterfront, your own private beach, and access to the big a** lake, so BYOB (bring your own boat). More like, bring your own boatload of money!
