WHAT THE STATE DISTRIBUTION SAYSAcross Maryland’s 19 current published direct-evidence ZIP reports, Zillow’s observed asking-rent index ranges from $1,391 to $2,535, a $1,144 spread around a $1,845 median. This is material within-state dispersion, not a single statewide asking-rent condition. The practical ZIP-level question is consequently not simply where the index is lowest; it is whether the local asking-rent level, household-income screen, renter burden, recent trajectory, and administrative benchmark offer a consistent or conflicting read. The displayed rows are a 12-report view selected to preserve measured extremes and fill by renter households. The distribution nevertheless contains only current published direct-evidence ZIP reports, not every Maryland ZIP, neighborhood, or rental property.
An affordability screen and a renter-burden estimate do not measure the same thing. In this distribution, when annualized against ACS median household income, current ZORI asking rent is 19.6%–51.1%, with a 27.3% median; that is a cross-source ratio rather than a count of households paying that share. The ACS estimate of renter households spending 30% or more of income on gross rent instead ranges from 40.9% to 60.1%, with a 49.4% median. ZIP 21043 illustrates the distinction: its $2,421 index produces a 19.6% income screen and a 41.0% reported burden share. In ZIP 21217, the lower $1,637 index produces a 51.1% screen and a 51.8% burden share. Income and burden inputs are ACS five-year estimates for ZCTAs, statistical areas that do not exactly match USPS delivery ZIPs.
Rent momentum requires a separate reading from volatility. In the direct monthly ZORI series, one-year annualized change spans −2.8% to 7.0%, whereas annualized volatility runs from 2.1% to 4.1%. ZIP 21224 has positive one-year growth and volatility at the low end of that range; ZIP 21216 has a negative one-year change and volatility at the upper end. Thus a latest growth sign alone does not describe the regularity of the monthly path. Volatility captures variation in that direct series, while maximum drawdown is a distinct measure of the largest historical peak-to-trough decline. These backward-looking measures clarify observed patterns, not a forecast of rent changes.
HUD supplies a different decision reference rather than a second observation of market asking rent. The ZORI-to-HUD two-bedroom ratio has a 94.3% median across published reports and spans 74.9% to 136.5%. It compares the ZIP-level ZORI asking-rent index with an FMR/SAFMR administrative bedroom standard, so a result above or below 100% does not establish what any specific unit should rent for. The comparison cannot substitute for property-level facts, including unit size, condition, lease terms, utilities, or concessions. It is best used alongside, rather than as an override of, the direct asking-rent series and the separate ACS income and burden evidence.
