A duplex in Chicago, IL costs $449,000 at the entry level and $550,000 at the median, across the 366 of 1,353 two-to-four-unit listings that passed the Foothold screen for August 2026. A one-bedroom rents for about $2,012 a month. Take the middle deal, ranked by what it keeps rather than by price: a $550,000 three-unit. Buy it with 3.5% down, live in one unit and rent the other two at the metro’s one-bedroom rent, and the month costs about $1,842, $169 less than renting. Chicago ranks #9 of 11 on the 2026 Foothold Index.

Dated note, 24 September 2026: the Foothold Index table shows Chicago keeping $184 a month against renting. That is the August 2026 edition at a 6.66% model rate. This page re-runs the figures at 6.71% (Freddie Mac PMMS, week of September 3, 2026).

It starts at the median surviving listing, $550,000, with $2,012 rent from the other unit at this week’s Freddie Mac rate. Change any number; the box scrolls for the full breakdown.

The short version: a two-to-four-unit home in Chicago costs real money to get into, but the rented units carry enough of the payment to beat renting. Entry price is $449,000, the median surviving listing is $550,000, and the rent from the two rented units in the median building covers enough of the payment that you keep $169 a month compared with renting.

Verdict: Mixed. A real Chicago FHA deal (North Austin 2-flat, $429,900, ~$450/mo cash flow) lands almost exactly on our numbers – unusually tight corroboration. The pushback is on our GATE, not our data: real FHA underwriting routinely accepts 47-50% DTI with compensating factors, so our 48.5% debt-to-income ceiling (crediting 75% of expected rent, the lender convention) is stricter than what many lenders will approve. The index keeps it on purpose: a deal that only clears with compensating factors is not the comfortable one this report is looking for.

How much does a duplex cost in Chicago in 2026?

1353 two-to-four-unit homes were listed in the Chicago metro when this ran. 366 of them passed my checks on a price floor, the FHA loan limit, gross rental yield, neighborhood violent crime, abandoned-property share and the five-year value trend. The seventh check, price per square foot, never ran here, because the listing feed had no square footage. The prices on this page are from those 366 survivors, not the raw feed.

What the two prices mean: entry ($449,000) is the 25th percentile, the price at which a quarter of surviving listings sit below you. Typical ($550,000) is the median. The median deal itself was a 3-unit, 6-bedroom building at $550,000 in ZIP 60641.

What is the average rent in Chicago in 2026?

Chicago: the rent figures on this page

A two-bedroom is about $1,720 on HUD’s FY2026 small-area fair market rents, the median across 49 ZIPs, and $2,550 on Zumper’s asking-rent data for May 2026.

A one-bedroom in Chicago rents for about $2,012 a month, the average of Zumper’s and Apartment List’s asking rents for mid-2026. The model scales that figure by ZIP with HUD’s FY2026 Small Area Fair Market Rents, so a building in a cheaper ZIP is measured against a cheaper rent. A two-bedroom is about $1,720 on HUD’s FY2026 small-area fair market rents, the median across 49 ZIPs, and $2,550 on Zumper’s asking-rent data for May 2026.

Why the two-bedroom figure is the lower one: the two rents are different series. HUD’s fair market rents are, in HUD’s words, “estimates of 40th percentile gross rents for standard quality units”, rent plus utilities, while the one-bedroom figure is the average of Zumper’s and Apartment List’s asking rents on units listed now. Because HUD’s figure sits at the 40th percentile and the one-bedroom is an asking rent, the HUD two-bedroom ($1,720) can print below the one-bedroom ($2,012), as it does here.

Why it matters twice: that rent is what you would pay to keep renting, and it is also roughly what the other unit pays you. The median surviving deal is a three-unit building, so two units are rented, and together they collect $3,893 a month. I count that rent only after a maintenance and vacancy allowance. It is not treated as free money.

What you pay each month living in one unit and renting out the rest

Chicago: your monthly cost, owning vs renting

A two-to-four-unit home, you in one unit, tenants in the rest. Their rent covers part of the payment. Lower is better.

Renting$2,012

Owning$1,842

The full payment on the median deal, with an FHA loan at 3.5% down and a 6.71% 30-year fixed rate, is $4,999 a month including mortgage insurance, property tax and insurance. The two rented units bring in $3,893 between them, about $1,947 each. After the allowance, your share of the month is about $1,842, against $2,012 to rent a one-bedroom nearby.

How the mortgage rate changes what you keep in Chicago

Mortgage rate	Median deal, per month, versus renting
5.00%	keeps $710
5.50%	keeps $537
6.00%	keeps $367
6.50%	keeps $231
6.71% (model rate)	keeps $169
7.00%	keeps $44
7.50%	$133 behind renting

What this means for you: at 5.00% the median deal keeps $710 a month; at 7.50% it is $133 a month behind renting. Watch the sign: the deal flips between those two rates, so the week you lock decides whether owning or renting wins here. Every figure is the same 366-listing screen re-run at each rate, prices and rents held.

How much income do you need to buy a duplex in Chicago?

Full payment$4,999On the typical building at 6.71%
Income, front-end guideline$193,514Payment at 31% of gross income
Income, back-end guideline$139,51043%, with no other debt
Median household income$90,770What the median household here earns

On the typical $550,000 building the full payment at 6.71% is about $4,999 a month. FHA’s front-end guideline (payment at 31% of gross income) puts that at $193,514 a year. The back-end guideline (43%, with no other debt) puts it at $139,510. Real approvals land between the two.

The part most buyers miss: an FHA lender can count 75% of the rented units’ rent toward your income when it qualifies you. The median household here earns $90,770.

The assistance test: HUD puts the Chicago area median income at $121,500 for a four-person household (FY2026). Most down payment programs cap eligibility at 80% of that, which HUD publishes as $97,200 for four people and $68,050 for one. The $193,514 front-end figure above sits $96,314 over that four-person limit. Household size and each program’s own cap decide it.

Down payment and assistance for a Chicago duplex

Your entry ticket: 3.5% down on a $449,000 entry building is about $15,715, before closing costs. IHDAccess Repayable (Illinois Housing Development Authority) offers up to $10,000 to eligible owner-occupant buyers, but only on a one- or two-unit home. A duplex qualifies. A three- or four-unit building, like the median deal here, does not (IHDA 2026 program matrix, read September 2026).^[S1] Locally, Neighborhood Housing Services of Chicago’s HomeGrown program offers up to $70,000 ($50,000 in Zone B), capped at 25% of the price, on single-family homes, condos, townhomes and two-unit properties, so it can reach a two-flat but not a three- or four-unit building like the median deal here.^[S3] Saving 10% of the local median household income, putting aside that deposit plus about $3,000 for other upfront costs takes about 25 months.

Renting the other unit to a Section 8 voucher tenant in Chicago

The short version

Main agency: Chicago Housing Authority (CHA). Payment standards set by CHA, one citywide schedule (Moving to Work agency; CHA says it does not use Small Area FMRs). Two-bedroom payment standard: Not published as a table; one citywide standard within 90% to 110% of FMR, and up to 150% of FMR (about $3,017 at the FY2027 two-bedroom FMR, in effect from October 1, 2026) in CHA Mobility Areas; ask CHA.
Two-bedroom ceiling: HUD FY2027 two-bedroom Fair Market Rent, from October 1, 2026 (Chicago-Joliet-Naperville, IL HUD Metro FMR Area) is $2,011.
Illinois source-of-income law: yes (2023); owner-occupied buildings of up to 4 units exempt. Local rule: Chicago’s Fair Housing Ordinance covers Section 8 Housing Choice Vouchers, and its exemptions section (5-8-050) lists no owner-occupied exemption, so as I read it the city rule reaches a building you live in even where the state rule does not; Cook County’s ordinance also covers vouchers.

The short version: with a Housing Choice Voucher, the tenant pays a share of the rent set from their income and the housing authority pays you the rest, up to a cap called the payment standard. In Chicago the main voucher agency is the Chicago Housing Authority (CHA). I did not find a current two-bedroom payment standard on the pages I read, so ask the housing authority for the figure that applies to the building.

Chicago’s metro is on HUD’s mandatory Small Area Fair Market Rent list, but CHA, a Moving to Work agency that HUD lets opt out, says it does not use them and sets one citywide standard within 90% to 110% of HUD’s Fair Market Rent. For scale, HUD’s FY2027 metro-wide two-bedroom Fair Market Rent for the Chicago-Joliet-Naperville, IL HUD Metro FMR Area, in effect from October 1, 2026, is $2,011 (FY2026: $1,781), and a basic-range payment standard runs from 90% to 110% of the published figure that applies.

As of September 2026, CHA can also approve, case by case, a payment standard of up to 150% of HUD’s Fair Market Rent for units in its Mobility Areas: community areas with 20% or less poverty and below-median violent crime, or moderate poverty and crime plus other positive indicators. Rent reasonableness still applies.

The catch: the payment standard is a ceiling, not an offer.

HUD’s rule is that “the PHA may not approve a lease until the PHA determines that the initial rent to owner is a reasonable rent”, judged against rents for similar unassisted units.

The housing authority’s monthly payment is the lower of the payment standard or the gross rent, minus the tenant’s share, and when the rent is above the payment standard, a family moving in cannot take on a share above “40 percent of the family’s adjusted monthly income”.

A rent well above what similar units nearby get can fail even when it sits under the payment standard.

The inspection: before the lease starts, HUD’s rule requires that “The unit has been inspected by the PHA and passes HQS”; HQS are HUD’s Housing Quality Standards. HUD is moving voucher inspections to its newer NSPIRE standard, but under Notice PIH 2026-18 housing authorities “may continue using HQS as previously defined or other HUD-approved inspection methods as their inspection standards until February 1, 2027”.

What Illinois law says about voucher tenants: Illinois law has covered source of income in housing since January 1, 2023: it is a civil rights violation to refuse to rent “because of” source of income (775 ILCS 5/3-102), which the Human Rights Act defines as “the lawful manner by which an individual supports himself or herself and his or her dependents”, and the state’s Department of Human Rights lists Housing Choice Vouchers among the protected sources.

The house-hacking detail is the owner-occupied exemption: Section 3-106 does not prohibit “Rental of a housing accommodation in a building which contains housing accommodations for not more than 4 families living independently of each other, if the owner resides in one of the housing accommodations”, so state law does not reach a two-to-four-unit home you live in, though its ban on advertising a preference still applies.

Locally: Chicago’s Fair Housing Ordinance covers Section 8 Housing Choice Vouchers, and its exemptions section (5-8-050) lists no owner-occupied exemption, so as I read it the city rule reaches a building you live in even where the state rule does not.

Cook County’s ordinance also covers vouchers. Source of income is not a federal protected class: the Fair Housing Act’s rental rule lists “because of race, color, religion, sex, familial status, or national origin”. This summarizes what the laws say; it is not legal advice.

One more 2026 fact: in December 2025 HUD recommended that housing authorities “Stop issuing new vouchers (except HUD-VASH and new FYI vouchers)” to keep 2026 costs inside their funding. Fewer new voucher holders may be searching while that lasts, so ask the housing authority whether it is issuing.

Payment standards change. This section uses HUD’s FY2027 Fair Market Rents, in effect from October 1, 2026; most housing authorities re-issue their payment standards after that, so confirm the current figure with the housing authority.

FHA loan limits in Chicago (2026)

FHA, the Federal Housing Administration, is the loan program that lets an owner-occupant buy a two-to-four-unit building with 3.5% down. It caps how large a loan it will insure, county by county. Cook County, IL sits at the national floor for 2026, so the standard limits apply. The cap rises with the number of units, which matters for house hacking: a duplex gets a higher limit than a single-family house.

Property size	2026 FHA limit, Cook County
1 unit	$541,287
2 units (duplex)	$693,050
3 units	$837,700
4 units	$1,041,125

The cap is not the binding check here. The typical entry price in Chicago is $449,000, about 65% of the two-unit limit, and 3.5% down on $449,000 is about $15,715 before closing costs. Every listing in my screen was already checked against the county FHA limit, so nothing that survived is limit-constrained.

What local reporting says about Chicago duplex prices

The model is a screen, not a local expert. Here is where independent reporting agrees with it, and where it pushes back.

Where outside sources agree

BiggerPockets case study: $429,900 North Austin FHA 2-flat cash-flowing ~$450/mo – our $449k entry + thin-positive keep, in the wild.
Cook County RTLO exempts owner-occupied buildings of 6 or fewer units – the house-hack case dodges the ordinance’s teeth.
Our spot-check listing (6244 S Seeley, $390,000) verified exact.

Where they do not, and why it matters

FHA’s TOTAL scorecard routinely accepts back-end DTI of 47-50%+ with compensating factors; our 48.5% debt-to-income ceiling is more conservative than practice, and that is deliberate.
Cook County’s 2024 reassessment: median city bill +16.7%, West/South side neighbourhoods +99-133% – concentrated EXACTLY where the affordable two-flat stock survives. Our tax line uses a metro rate; the within-metro skew means our cheap-tail listings will see worse than metro-average tax growth.
Two-flat stock is shrinking (~21,000 2-4 unit rentals lost 2011-2015 to deconversion) and the DePaul institute calls the surviving stock ‘in distress’ – with no sqft data, none of it condition-screened.

Questions people ask about buying a duplex in Chicago

How much does a duplex cost in Chicago?

A duplex in Chicago costs $449,000 at the entry level (25th percentile) and $550,000 at the median, measured across the two-to-four-unit listings that passed the 2026 Foothold screen. Both are list prices.

What is the average rent in Chicago in 2026?

Average rent in Chicago is about $2,012 a month for a one-bedroom, the average of Zumper and Apartment List asking rents for mid-2026, and about $1,720 for a two-bedroom on HUD FY2026 small-area fair market rents, the median across the ZIPs in this report.

Is it cheaper to own a duplex than to rent in Chicago?

Owning the median two-to-four-unit and renting the other two units costs about $1,842 a month all-in, against about $2,012 to rent comparable space, so owning keeps about $169 a month while building equity.

Why does Chicago rank #9 on the Foothold Index?

The Foothold Index rank is defined by three weighted scores: how affordable it is to get in, what the deal does for your monthly cash, and how durable the local economy looks over a decade. Chicago ranks #9 of 11 on that combination, out of 83 metros screened.
