This page describes ZIP 21230. Whether buying beats renting depends on the price you'd pay, your down payment, and how long you'd stay — TerraVue simulates about 1,000 market scenarios on those inputs and returns the probability, not a single guessed number. It'll start with 21230's real appreciation and rent already loaded.
Analyze a property free →Appreciation comes from the FHFA House Price Index — a repeat-sales index that tracks the same homes over time, which is why it isn't distorted by a change in the mix of what sold in a given year. TerraVue reads it at the ZIP level, back to 1975 where coverage allows.
The forward estimate blends 60% of the longest available look-back (20 years where available) with 40% of the most recent 3 years. Long-run history is the more reliable signal, but a market that has genuinely changed pace should not be ignored — the 60/40 split is the compromise, and it's the same figure TerraVue's simulation uses.
The national comparison is the population-weighted average of these same blended ZIP-level figures, so it compares like with like.
Over the past 20 years, prices have risen about 1.01% a year, based on 48 years of FHFA repeat-sales data (1978–2025). Over the most recent three years the pace has been 1.79%, which makes this market stable. TerraVue's forward estimate blends the two at 1.32%.
On appreciation alone it runs -2.70pp versus the national average. But whether buying beats renting there depends on the price of the specific home, your down payment, and how long you'd stay — TerraVue simulates that directly rather than inferring it from the average.
Around $2,170 a month, from the Zillow Observed Rent Index (all homes).
