Negative Leverage — IRR / Tax Play Cap Rate: 4.0%  |  30yr Rate: 6.8%
Leverage reduces cash returns at current rates.

The current 30-yr mortgage rate (6.8%) exceeds the estimated cap rate (4.0%). Financing reduces your cash-on-cash return below the cap rate. Markets like this may still make sense as IRR plays — factoring in appreciation, depreciation, and a future refinance when rates drop.

About Repit School Scores

Traditional school ratings rely heavily on standardized test scores, which often reflect family income more than school quality. Repit takes a different approach.

We evaluate schools based on factors that research shows actually impact educational outcomes:

  • Class Size — Smaller classes mean more individual attention
  • School Funding — Resources available for programs, staff, and facilities
  • Community Factors — Neighborhood characteristics that influence student success
  • School Environment — Size, type, and structure

Scores are updated annually using federal education data.
