Madison, WI Rent Report: Market Rent vs. HUD Fair Market Rent by ZIP

Madison has three different rent numbers that should not be treated as interchangeable: an all-size ZIP market index, a county HUD reference and the City of Madison CDA's adopted voucher payment standard. The distinction becomes especially useful downtown, where the CDA publishes different standards for ZIP codes 53703 and 53715.

Reviewed October 3, 2026, this report explains those differences, shows the live rent data and works through a hypothetical property's cash flow. It also separates a stable annual budget from turnover and rent-increase timing, which can change the first year's result even when the monthly headline rent looks adequate.

Market rent and voucher rent by ZIP code in Madison

Our October 3 data check included 12 Madison ZIP rows. Most market observations were from July 2026; ZIP 53717's latest observation was June. The county-based HUD comparison was the same across all twelve rows.

Market rent is the Zillow Observed Rent Index, which covers all unit sizes. Dates and HUD geography are shown for each row.The percentage compares a bedroom-specific HUD reference with an all-size index; it is not a matched-unit premium, an adopted payment standard or an approved rent. Check bedroom-matched comps, the authority's schedule and utility allowance before underwriting.

That repeated HUD figure is not evidence that every Madison neighborhood has the same voucher payment standard. It means this comparison uses a county FMR benchmark where a ZIP-specific HUD reference is not supplied in the loaded comparison. The market denominator can change by ZIP while the HUD numerator stays constant.

The resulting percentage is a research ratio, not a rent premium an owner can collect. It compares an all-size index with a bedroom-specific reference. Before setting the rent for a two-bedroom apartment, find two-bedroom comparables with similar condition, parking, laundry and utility responsibility. Record any free-rent concession and the date of the listing or lease.

The Madison rent lookup is a useful starting point for geography. It cannot establish the achievable rent of a particular duplex or condominium. Keep the property's supported rent in a separate field from the index so a future data refresh does not silently become your new underwriting assumption.

HUD Fair Market Rents for Dane County

The live table below carries HUD's loaded fiscal year. It is a county gross-rent reference, including tenant-paid utility costs, rather than a promise of subsidy or approval of a proposed lease.

For CDA-administered vouchers, the city publishes its own adopted standards. The CDA voucher limits page lists the following selected amounts effective July 1, 2026, checked October 3:

These amounts are a dated excerpt from the authority schedule. They do not update automatically with the live HUD block. Confirm the applicable standard with the agency administering the household's assistance; a City CDA schedule should not automatically be applied to a different housing authority's voucher.

For a simplified two-bedroom comparison with a hypothetical $250 tenant utility allowance, the general schedule less that allowance is $1,600, while the downtown schedule less the allowance is $1,850. Neither figure establishes approved contract rent. Rent reasonableness, household circumstances, the actual allowance and other program requirements still need review.

The $250 allowance is illustrative, not a published Madison quote. The CDA lists utility schedules by building type, including its duplex, townhouse and rowhouse schedule effective May 1, 2026. Match the actual services and building category. Our Section 8 rent calculation guide explains why subtracting an allowance is only one part of evaluating a tenancy.

How rents in Dane County have moved

Dane County typical rent, last published month of each year. Source: Zillow Observed Rent Index (all home types, smoothed and seasonally adjusted), refreshed monthly. A partial-year observation compared with the prior December is not a same-month year-over-year change.

At the October 3 review, the loaded county series was approximately $1,648 for August 2026 versus $1,603 for August 2025, a same-month increase of about 2.77% using the unrounded observations. This is county context, not a measured rent increase for an individual building.

An annualized budget should not automatically compound by 2.77% next year. A renewed lease, a newly marketed unit and a property under renovation have different cash calendars. The live history can advance after this review, so use its displayed dates and avoid comparing a partial year's latest reading with a full prior year's December as though they were the same period.

A practical first pass is flat supported rent, current documented expenses and a separate downside vacancy case. The vacancy guide explains how to translate expected empty months into an income assumption rather than choosing a percentage because the market appears strong.

What this means if you own a rental in Madison

Consider a hypothetical two-bedroom property with $1,850 monthly contract rent. The example happens to equal the simplified downtown reference above, but no actual unit or voucher approval is implied. Use matched comparables to support rent independently.

Assume 4% vacancy and collection loss, management at 8% of collected income, and $1,000 monthly principal and interest. The property-specific tax, insurance, maintenance and utility amounts below are modeling assumptions, not typical Madison quotations.

This property is slightly negative before acquisition costs and income taxes. Its break-even contract rent is approximately $1,887 monthly: annual fixed operating costs, debt and reserve of $20,000 divided by twelve and by 88.32%, the amount left after the modeled loss and management charges.

At $2,000 supported monthly rent, the same budget produces about $1,197 annually after reserve. That $150 monthly gross improvement contributes about $1,590 annually after loss and management. If a downtown alternative costs $1,800 more per year to operate, the higher rent alone would not compensate. Compare two complete property budgets instead of ranking them by payment standards.

Check the tax reassessment guide before treating a seller's bill as a permanent expense. Build replacement reserves from inspected components with the capital reserve worksheet. A reserve contribution reduces cash available to spend, while a later roof invoice draws on the accumulated balance; do not count the same funded cost twice.

Turnover and renewal timing need their own rows

Suppose the example collects eleven full months of rent, has no other collection loss and incurs $1,500 of turnover work. With the same annual fixed costs, debt and reserve, first-year cash flow is approximately negative $2,778. That replaces the 4% stabilized loss allowance with a known one-month vacancy. Subtracting both would overstate the modeled loss.

The CDA's housing provider guidance calls for a rent-increase request at least 60 days before the new lease starts. Initial-term restrictions and approval requirements also apply. Plan the cash calendar around the approved effective date rather than assuming a requested increase starts immediately.

For example, an otherwise supported $100 monthly increase that takes effect two months later than the budget expected produces $1,000 of extra gross rent during that twelve-month window instead of $1,200. At 8% management and with no additional vacancy or collection loss, the difference is $184 in net receipts. This is a timing illustration, not a claim that CDA processing always takes two months.

Where these numbers come from

RentalCalcs' live ZIP and county tables use loaded Zillow observations and HUD FMR and SAFMR data. The Zillow indices blend unit sizes; the HUD references have specific bedroom counts and fiscal years. Neither is a database of signed leases for the subject property.

CDA standards and provider rules are separately dated primary sources. Recheck them when a lease or utility arrangement changes. The cash-flow calculations are original hypothetical examples, with no property inspection, lender quote or rent approval implied.

Use the Section 8 analyzer for the relevant unit and rent assumptions, then the single-family calculator for a complete operating and financing case. Saving the verified inputs with an analysis makes it easier to compare a downtown property with an alternative on the same basis: supported net cash flow and the cash needed to reach it.
