Market Analysis: 57761 New Underwood

This part of Pennington County is not an easy win. The 57761 ZIP registers softness in key indicators, and the playbook that works in cleaner markets often stalls here.

The 57761 ZIP can work — but only with a tight operating hand. Remote landlords and passive investors tend to struggle here more than the underwriting suggests.

ZIP 57761's metrics run below Pennington County's averages on price growth and tenant stability. Investors who ignore that regional gap tend to relearn it the hard way.

Looking more closely, 1,274 residents fill the ZIP, renter turnover runs higher than neighboring postal codes and delinquency risk is a real line item rather than a theoretical one.

The right play in 57761 usually involves deep tenant screening, aggressive delinquency response, and a conservative capex buffer. Anything less, and the discount can turn into a trap.

Negative Leverage — IRR / Tax Play Cap Rate: 1.7%  |  30yr Rate: 6.8%
Leverage reduces cash returns at current rates.

The current 30-yr mortgage rate (6.8%) exceeds the estimated cap rate (1.7%). 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.

  • 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.
