Diffusion models forecast home price ranges, claiming better accuracy than Zillow's baseline.

Strengths
  • •Schrödinger Bridge diffusion architecture is novel for real estate valuation.
  • •Probabilistic P10/P50/P90 bands offer more utility than single-point estimates.
  • •API access allows investors to integrate forecasts into deal underwriting workflows.
Weaknesses
  • •Hard to verify accuracy claims without long-term public track record.
  • •Limited state coverage contradicts the 'Nationwide' claim on the landing page.

Post Description

I built homecastr.com because you can't easily see where home prices are headed, not even on Zillow.

I used an FT-Transformer & Schrödinger Bridge diffusion model, trained on 20+ years of ACS microdata & 8 FRED macro series.

This approach beats Zillow's baseline on 1-year held-out error, achieving 8.0% vs Zillow's 8.4%.

Happy to answer questions about the architecture or anything else!
