Excel Model Dragging? Try This Tool


It's been a while since my last newsletter. Life and deal flow got in the way, but I'm back.

Three things.

  1. I'm looking for real estate family business or family office principals and executives willing to sit for a short interview. These conversations feed directly into the "Real Estate Family Business Management" course I teach at New York University. I'm looking for anecdotes, stories, and context on succession, governance, and control. If you or someone in your network fits that profile and is open to a conversation, please let me know. Class material and forthcoming book research, fully anonymized, no quotes without approval. Reply to this email or email me at j.kahr@nyu.edu
  2. Have a slow Excel model? Don't know why? Need to find out which worksheet or cell range is slowing you down? Here's a tool I built forever ago that I still use today. It's called "Timer Tester." The link is here: https://www.kahrrealestate.com/free-stuff/
  3. I'm building a couple of new courses for my on-demand course platform; I'm torn between building a debt modeling course and a lease analysis course first. Of course, if you're seeing a hole in the market that needs filling, let me know. You can view all of my current on-demand course content here: https://courses.kahrrealestate.com/

Anything else going on that you'd like to share? I'm all ears.

One allocation percentage cannot describe two opposite strategies, and averaging them erases the story. The number hides a barbell Every...

Why Family Offices Are Becoming Property Companies, Not Fund LPs The mechanics now favor direct ownership over fund LP positions on every axis that matters to a family office. Three reasons why. Structure beats speed. Family offices closed 55 direct real estate transactions in the first half of 2026, across 39 buyers, according to FINTRX. Thirty-one of those buyers were single-family offices, versus eight multi-family offices. SFOs have no investment committee cycle, no fund duration clock,...

While I generally believe that rent control is a bad idea, there are gradiations of horrible. That said, rent control done well and rent control done badly are sitting side by side right now, and the contrast is instructive. Jersey City ties its annual cap to CPI or 4%, whichever is lower. Capital improvements at vacancy get a fixed, self-executing surcharge, $1.35 per $100 of cost up to $5,000 and $1.55 per $100 above that, no board hearing required. Spend $10,000 renovating a unit at...
