When my husband and I got married, we bought our first place—a brand-new, 1.5-bedroom condo—in Bedford–Stuyvesant, Brooklyn. At the time, the Bed–Stuy neighborhood was rough—for example, a biker gang that loved to throw huge all-night parties was headquartered at the end of our block, and there were abandoned buildings every few feet, often rustling with the sound of homeless inhabitants. Back in the early aughts, this ZIP code was not for the faint of heart.

But at $375,000, a solid C-/D neighborhood was what we could afford in NYC, and our place was new and huge (for Brooklyn) at 1,200 square feet. Plus, I had a hunch. When we first toured the apartment, I went up on the roof and looked out over the neighborhood. From that vantage point, I could see three luxury buildings going up within a few blocks of us. I knew this neighborhood was about to change.
