Market Analysis: 66536 Saint Marys

The 66536 ZIP in Saint Marys, KS is a local-operator market. Outside capital chasing a $290K entry has to pair deep knowledge with the discount.

Rent of $810/mo on a $290K basis reads well until vacancy, delinquency, and capex enter the model. The honest cap rate in 66536 sits below the stated 0.0% once reality is priced in.

In the broader KS picture, 66536 is a reminder that not every low-priced ZIP is a value-add opportunity — some are simply distressed, and the difference matters.

A robust renter share of 27% in 66536 is not, on its own, a problem — but paired with below-average income and high mobility, it changes the operating playbook.

The 66536 ZIP fits a narrow investor profile — hands-on, patient, and willing to accept that the cap rate on paper is not the cap rate in reality.

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.
