From the front, 91 Birch Ave. in Richmond Hill looks like your standard-issue 1970s beige-brick bungalow—modest, boxy, and a little worse for wear. That's over 29,000 square feet of south-facing, prime suburban real estate—in other words, practically a private park. That said, it does have a finished walkout basement, which could bring in some rental income while you sketch out your architectural masterpiece. But don't expect a windfall—the entire home has been leased out for just $2,300 a month since 2018, and rental prices in Richmond Hill have actually taken a dip in recent years. Homes in the area have gone for well over $14 million, so this listing price isn't as wild as it might seem at first glance.
