Market Analysis: 99350 Prosser

On the rental side, ZIP 99350 has challenges — vacancy pressure, softer price growth, and tenant stability concerns sit alongside the $426K median. It rewards specialists, not generalists.

Distressed markets are won on execution, not on spreadsheets. ZIP 99350 reflects the profile where tenant screening, deferred maintenance, and local relationships determine the outcome.

Within WA, ZIP 99350 trails on several market indicators that neighboring Benton County submarkets outperform. The gap is real and resilient enough to shape underwriting.

A impressive renter share of 37% in 99350 is not, on its own, a problem — but paired with below-average income and high mobility, it changes the operating playbook.

Strategically, 99350 can be a high-return sleeve of a diversified portfolio — but it should not be the whole portfolio, and it should not be someone's first deal.

Negative Leverage — IRR / Tax Play Cap Rate: 2.7%  |  30yr Rate: 6.8%
Leverage reduces cash returns at current rates.

The current 30-yr mortgage rate (6.8%) exceeds the estimated cap rate (2.7%). 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.

About Repit School Scores

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.
