The steps, the pets, the schleps, and the forgets

Solving the Duplex Dilemma

December 10, 2025

If you’re just joining us: Jamie and Morgan are devoted pet parents with five furballs who adore them—and, well, tolerate each other at best.

While one might think it’s the Shih Tzus’ fault — Sun Tzu, in particular, as Bronx Tzu spends most of the day sleeping. But, it’s really the Scottish Folds’ fault: Fuddy, Duddy, and MacGillicutty.

The solution to this furry frenemy fiasco? A duplex — a home that lets everyone live (happily) together, but separately, when needed.

Jamie and Morgan have solid financials , plan to put 20% down , and want to keep monthly overhead under $15,000, all-in. (Right, it’s a healthy budget.)

In exchange for excellent credit, they’ll secure a 6.19% rate on a 30-year fixed mortgage .

And, naturally, they’re all in on the LES —and yes, the k’nnection has to do Yonah Schimmel’s legendary knishes .

Today, we’re checking out the first five duplexes that will help keep the peace (and the pets happy) . Onward to Duplex City to solve the Duplex Dilemma!
