The #1 Predictor of Neighborhood Appreciation
I'm writing this from a real estate conference where I just got my hands on something interesting: RealAI, a beta real estate ChatGPT loaded with institutional-grade data that's supposedly built for massive investment analysis.
 
Naturally, I decided to test it on the my favorite question:
 
What are L.A.'s next hot neighborhoods?
 
The AI-to-AI Strategy
 
Here's the best AI tip I picked up: use one AI to craft the perfect question for another AI. So I had ChatGPT help me formulate this query for RealAI, using well-established criteria for rapid neighborhood value increases:
 
“Which Los Angeles neighborhoods currently have: 1) High rental rates (70%+), 2) Low median home prices relative to LA average, 3) Recent increases in investor purchases, and 4) Proximity to already-gentrified areas?”
 
Two clear winners emerged:
  • Adams-Normandie
  • Harvard Heights
Cool. Both nice little pockets, and both showing "classic pre-gentrification signals," according to AI. Then I noticed something curious: both are Historic Preservation Overlay Zones (HPOZs).
 
The runner-ups? Pico-Union, Lincoln Heights, and Leimart Park.
 
Also HPOZs. Very interesting.
 
The HPOZ Connection
 
Here's what an HPOZ means: LA has 35 zones where you can't make exterior changes that break the historic character. No stuccoing your Victorian. No tearing down Craftsmans for modern farmhouses. A committee of neighborhood volunteers decides what's allowed, and yes, it gets contentious.
 
But HPOZs guarantee two things:
  1. The neighborhood already has nice houses
  2. They'll stay nice
This is why Hancock Park and Windsor Square are so magical—and why our neighborhood, Los Feliz (not an HPOZ), currently has a house in the hills where a lunatic has painted a purple-and-white chessboard on his exterior wall, complete with giant plastic gold chess pieces jutting out—and there’s not a thing we can do (don’t get Lori started).
