What a rent-control chart means if you are choosing to rent or buy

How to read the Financial Times rent-control chart in Crémieux's October 4, 2026 post if you are deciding whether to keep a lease or buy.

Published: 2026-10-04

Key takeaways

  • The Financial Times graphic in Crémieux's October 4, 2026 post puts rents in controlled apartments mostly in the beneficial group, with an unclear cluster near the middle. Nearby rents, housing quality, available homes, and new construction cluster on the harmful side. The graphic's subtitle says the circles are results of 112 studies.
  • Crémieux's conclusion in that post: rent control helps people whose rents get limited, and it hurts everyone else. He writes that it pushes up rents, pushes down new building, and makes cities worse, and he calls it horrible policy. The post quotes his November 4, 2025 thread.
  • Konstantin Kholodilin's August 2024 summary of the review reports 196 studies across 8 domains, from 206 works covering 1967 to 2024. Of 65 studies on controlled rents, 56 find lower rents, 6 find no effect, and 3 find higher rents. Of 17 studies on uncontrolled rents, 14 find higher rents, 2 find no effect, and 1 finds lower rents.
  • The thin spots are on the graphic and in the author's own words. Gray circles are filed as unclear, including on controlled rents and on homelessness. The paper is a literature review in the Journal of Housing Economics, volume 63, March 2024, article 101983. His December 5, 2022 discussion paper says the overall impact on the welfare of society is not clear.
  • If your rent is already capped, that cap is the benefit the controlled-rent results describe. If it is not, the uncontrolled-rent results mostly point the other way. A purchase comparison still uses your rent, your cash to close, and a loan you price yourself.

If you are weighing a lease against a purchase, the chart going around this week is about who a rent cap actually helps. On October 4, 2026, Crémieux (@cremieuxrecueil) posted a Financial Times graphic of a rent-control literature review. His summary is that the policy helps people whose rents get limited and hurts everyone else.

The graphic's credit line names John Burn-Murdoch and the Financial Times. The post says a new Financial Times piece created the visualization. The title on the graphic is "Rent controls help existing tenants but have many wider negative impacts." This page describes the pattern and links out. It does not copy the graphic.

What does the chart show?

The subtitle says the circles are results of 112 studies. Every circle is one study result, grouped as harmful, unclear, or beneficial. That 112 is the graphic's own label, as it appears in the October 4 post. It is not a count made for this page.

The rows, from top to bottom, are rents in controlled apartments, rents in other nearby apartments, housing quality, homelessness, the number of available homes, new housing construction, and overall cost/benefit. The scale runs from harmful on the left, through unclear in the middle, to beneficial on the right.

Rents in controlled apartments sit mostly in the beneficial group, with a smaller cluster in the unclear group near the middle. That row is the part of the title about help for existing tenants.

Rents in other nearby apartments, the number of available homes, and new housing construction cluster on the harmful side. Unclear circles sit near the middle of those rows, and circles also sit on the beneficial side. Housing quality clusters on the harmful side, with unclear circles near the middle. Homelessness has circles in the harmful group, the unclear group, and the beneficial group. Overall cost/benefit clusters on the harmful side, and circles also sit on the beneficial side of that row.

What did Crémieux conclude?

The October 4, 2026 post says a new Financial Times piece visualized this study. The conclusion he draws is direct. Rent control helps people whose rents get limited, but it hurts everyone else. It pushes up rents, pushes down new building, and makes cities worse. He calls it horrible policy.

The post quotes his November 4, 2025 thread. That thread opens on the same split: most studies agree that rent-controlled units have lower rents, the supply of rentable units goes down, and uncontrolled units see their rents increase.

That reading follows the main clusters on the graphic. "Horrible policy" is his judgment. The graphic still files some results as unclear, and several of those rows also have circles on the beneficial side.

Where is the evidence thinner?

The gray circles are the first thin spot. The graphic files some results as unclear, including on the controlled-rent row and on homelessness. A row with circles in more than one group is a split result, even when one group holds the cluster.

The second thin spot is the kind of research this is. Konstantin A. Kholodilin's paper, "Rent control effects through the lens of empirical research: An almost complete review of the literature," is a review of many studies. It ran in the Journal of Housing Economics, volume 63, March 2024, article 101983. The publication date, volume, and article number are the Crossref record for DOI 10.1016/j.jhe.2024.101983. The open record on RePEc and the ScienceDirect page point at the same article. RePEc's abstract says rent controls appear quite effective at slowing the growth of rents on dwellings subject to control, and that the policy also leads to a wide range of adverse effects affecting the whole society.

A review pools places, years, and rule designs. It is a literature review. It is not a result for one city, and it does not say what your lease will do next year.

His August 2024 summary of that review, "Rent Control: Does it work?", reports an analysis of 196 studies across 8 domains, drawn from 206 works covering 1967 to 2024. The domain counts in that summary are these:

  • Controlled rents: 56 of 65 studies find lower rents, 6 find no effect, and 3 find higher rents.
  • Uncontrolled rents: 14 of 17 studies find higher rents, 2 find no effect, and 1 finds lower rents.
  • Housing quality: 15 of 20 studies find lower quality, 5 find no effect, and none find higher quality.
  • Rental supply: 12 of 16 studies find less supply, 3 find no effect, and 1 finds more supply.
  • Construction: 11 of 16 studies find less construction, 4 find no effect, and 1 finds more construction.
  • Mobility: 25 of 26 studies find lower mobility, 1 finds no effect, and none find higher mobility.
  • Misallocation: all 14 studies find more misallocation.
  • Homeownership: 13 of 22 studies find higher homeownership, 5 find lower homeownership, and 4 find no effect.

The "no effect" lines are the unclear results in prose. They come from the August 2024 summary, not from counting circles on the graphic. The graphic's 112 and the summary's 196 are different figures. This page does not reconcile them. The summary's eight domains are controlled rents, supply, construction, quality, mobility, misallocation, homeownership, and uncontrolled rents. The graphic's rows also include homelessness and overall cost/benefit, and they leave mobility, misallocation, and homeownership off the picture.

On overall cost and benefit, the author's earlier wording is more cautious than a single cluster. In the DIW Berlin discussion paper dated December 5, 2022, he writes that unintended effects diminish the net benefit of rent control, and that the overall impact on the welfare of society is not clear. The August 2024 summary says the study is far from a complete picture of the net effects, and that a cost-benefit check belongs before a cap is imposed.

What does this change if you are choosing to rent or buy?

Start with the lease you have.

If your rent is already limited, the controlled-rent results are the ones that describe your situation. In the August 2024 summary, 56 of 65 studies find lower rents in controlled housing, 6 find no effect, and 3 find higher rents. The same summary finds lower mobility in 25 of 26 studies. People who already have the cap tend to stay. Leaving for a purchase means giving up a limit the review treats as real for most of the studies it covers. Price that against cash to close, the loan type, and how long you expect to stay. The first-time buyer guide walks the purchase path. The affordability calculator and the payment calculator take numbers you type.

If your rent is not limited, read the uncontrolled-rent line. In that same summary, 14 of 17 studies find higher rents in housing that is not subject to control, 2 find no effect, and 1 finds lower rents. A cap on another building is a different lease from yours. The nearby-rent row on the graphic clusters on the harmful side for that reason.

Supply and construction sit on the same side of the graphic, and the summary's counts agree with that cluster more often than not: 12 of 16 studies find less rental supply, and 11 of 16 find less construction. Fewer available homes and less new building are the backdrop if you are waiting for a place to rent or a place to buy. Housing quality is the maintenance question: 15 of 20 studies find lower quality, 5 find no effect, and none find higher quality. A cheaper controlled rent can come with a building the landlord spends less on.

Homeownership is the split that matters if the question is whether to buy. The summary finds higher homeownership in 13 of 22 studies, lower homeownership in 5, and no effect in 4. The December 5, 2022 discussion paper treats that result as less settled than the rent results. Some of the increase can come from landlords selling or converting rentals. Some tenants in controlled units have less reason to become owners. A higher ownership rate in a study is a market outcome. It is a separate question from whether a purchase fits your household.

Loan types, the down-payment guide, and the weekly national rate snapshot are the pages for the product and the benchmark. A written offer still depends on credit, the program, and the day a lender sets the price. This page is a reading of a chart and a literature review.

This note is general education for people comparing a lease with a purchase. It is not financial advice, a loan offer, a rate lock, or a payment quote.

Frequently asked questions

If my rent is already capped, what do these studies say?

In Kholodilin's August 2024 summary, 56 of 65 studies find lower rents in controlled housing, 6 find no effect, and 3 find higher rents. The Financial Times graphic puts that row mostly in the beneficial group, with an unclear cluster near the middle. Those figures are from the summary at https://iea.org.uk/wp-content/uploads/2024/08/Rent-Control-Does-it-work-Dr-Konstantin-A.-Kholodilin.pdf. They describe controlled units in the studies, not your next lease offer.

If my building is not under a cap, should I expect my rent to fall?

The August 2024 summary says 14 of 17 studies find higher rents in housing that is not subject to control, 2 find no effect, and 1 finds lower rents. The graphic's row for rents in other nearby apartments clusters on the harmful side. A cap on someone else's lease is a different contract from yours.

Is this a result for my city?

The journal article is a literature review, Journal of Housing Economics, volume 63, March 2024, article 101983. The August 2024 summary covers 206 works from 1967 to 2024 and reports 196 studies across 8 domains. A pooled review is the source. It is a review across many studies, rather than a finding for one city.

Does the chart say rent control is a reason to buy?

The August 2024 summary finds higher homeownership in 13 of 22 studies, lower homeownership in 5, and no effect in 4. The December 5, 2022 discussion paper treats that split as less settled than the rent results, because landlords may sell or convert rentals, and tenants in controlled units may have less reason to buy. Compare your lease with a purchase using your own rent, cash to close, and a written lender offer.
