The snake bark maples are a tough group to differentiate from one another. Its too bad we have so few! This one is distinct due to its red petioles and lacking reddish hairs on the lower leaf surface. A. davidii has leaves that are rarely strongly lobed, usually only 3 lobes if any at all. There as several A. davidii specimens around but are not close to the street to see.
Better go see this one soon, just saw the house was for sale and you never know what people will do when they move in.
