Housing shortage investment: which assets actually hold up?

Real estate investment in a housing shortage: when supply falls short, not every asset benefits equally

France is experiencing its most severe housing crisis in thirty years. More than one million people lack a place to call home. Evictions have reached a historic high. And yet the stock of rental properties continues to shrink, not only because too little is being built, but because private landlords are actively leaving the market.

Against this backdrop, real estate investment in a housing shortage might seem like an obvious opportunity. But it is a misleading one. Rental pressure benefits certain asset types and penalizes others, sometimes within the same city. An investor who fails to make that distinction risks buying in the wrong location, in the wrong format, with the wrong protections in place.

This article compares the main types of residential assets through the lens of their genuine resilience to the shortage: small units, student residences, coliving, intermediate housing, and apartment buildings in mid-sized cities. For each, we examine the mechanisms that support returns, the factors that constrain them, and what tokenization concretely changes for the individual investor.

What the shortage actually changes for an investor

Rental pressure and investment opportunity are not the same thing

Rental pressure measures how hard it is for a tenant to find housing. It is real, well-documented, and worsening. In 2025, the national stock of available rental properties declined by 7%. In markets such as Paris, Nice, and Lyon, that stock represents less than 1% of the units managed by large property management firms. The figure speaks for itself: in these markets, virtually every property is occupied at any given time.

But rental pressure and investment opportunity are not synonymous. A market where tenants compete fiercely for a flat can simultaneously be a market where yields stagnate or even fall, because rents are regulated, because acquisition prices have been pushed too high, or because local taxes weigh on net profitability. Investors must therefore read two markets in parallel: the rental market, on the demand side, and the investment market, on the acquisition and yield side. These are distinct indicators, and their positive alignment is never guaranteed.

The mechanisms that inflate returns in a supply-constrained market

When supply contracts without any weakening in demand, several dynamics work in the landlord's favor. Vacancy rates collapse: a property is re-let within days, sometimes within hours in the tightest markets. Tenant turnover slows, reducing refurbishment costs and unproductive periods between tenancies.

One central paradox deserves to be stated clearly: 47% of private landlords surveyed in a recent study said they were considering, or had already considered, withdrawing their property from the rental market. This withdrawal, driven by regulatory constraints and a perceived erosion of profitability, itself feeds the shortage. In areas without rent controls, upward pressure on rents increases mechanically. That benefits the landlords who stay, provided they have chosen assets in the right segments.

Small units: first to benefit, but not always the most stable

Studios and one-bedroom flats in high-demand areas: vacancy rates close to zero

Studios and one-bedroom flats concentrate rental demand in major university cities and dense employment zones. They are the first assets to benefit from a housing shortage: their limited size makes them accessible to the widest pool of prospective tenants, which mechanically reduces vacancy risk. In the tightest markets, a well-located one-bedroom flat rarely stays available for more than 48 hours.

The gross yield profile is generally higher than that of larger units, with rents per square metre at a premium. But the management cost per unit is also higher: more frequent turnover, more regular refurbishments, and recurring agency fees. These costs erode the net yield and must be factored in from the outset. Our guide on how to calculate the return on a rental property investment walks through the key metrics to master before committing to any asset.

Rent caps as a limiting factor in major cities

Rent regulation applies in 2026 to 69 French cities. Its future will be decided by the end of June 2026, when a government report is expected to inform a decision on whether to extend or abandon the framework. This is a live issue for any investor already positioned, or considering a position, in these markets.

The regulation caps rents at a reference level set by zone. In theory, it protects tenants. In practice, its effectiveness is disputed: close to 28% of rental listings in regulated zones are reported to fall outside the prescribed limits. That figure raises questions about both the system's usefulness for tenants and its actual weight on the effective returns of compliant landlords.

For an investor in a regulated zone, the risk is twofold: being subject to a capped rent while competitors ignore the rules, and navigating a regulatory uncertainty that the June 2026 decision should resolve, one way or the other.

Real estate investment in a housing shortage: student residences and coliving

Why captive student demand secures rental income flows

France has more than three million students. The supply of housing specifically designed for this population covers only a marginal fraction of that demand. The consequence is mechanical: well-located private student residences post occupancy rates close to full capacity, with predictable seasonality and short leases that limit exposure to prolonged arrears.

The average gross yield on a student residence in France ranges from 3.5% to 5%, depending on location and operator quality. In cities such as Rennes or Lille, however, documented yields of 6% to 8% have been recorded, supported by sustained student demand and still-reasonable acquisition prices. The gap with the national average is significant and makes a strong case for rigorous geographical selection rather than a generic approach.

The commercial lease model with a specialist operator allows the investor to delegate all operational management entirely. This is a structural advantage for those who want residential real estate exposure without managing tenant relationships on a day-to-day basis.

Coliving as a response to the shortage of affordable housing in city centres

Coliving addresses a demand that neither conventional housing nor student residences cover: mobile adults, young professionals, and workers on temporary assignments, who are looking for furnished, flexible and socially active accommodation in high-pressure urban markets.

The strength of the coliving model in a supply-constrained market lies in its ability to intensify the use of a given space. Where a conventional flat houses one household, a coliving unit houses three or four people, with shared communal areas. The rent per occupant is lower than the open market, which sustains attractiveness for tenants, while the total income per square metre is higher for the landlord. Structural demand in major cities is growing, and this format is not subject to the same regulatory pressures as conventional housing on several counts.

Intermediate and affordable private rental housing: an underestimated segment

Middle-income demand that falls between public and private markets

There is a category of households that rarely features in the public debate on housing: those whose incomes are too high to qualify for social housing, but too low to absorb open-market rents in high-demand areas. These are middle-income households, often families with children and stable employment, who represent a rental demand profile that is exceptionally low-risk.

Intermediate housing targets precisely this population, with rents set below the open market but above social housing ceilings. Governments support this segment through tax incentives and public-private partnerships. Demand structurally exceeds supply in high-pressure areas.

Moderate yield, low tenancy risk: a defensive trade-off

Intermediate housing does not post the highest yields. It is a defensive asset, whose value lies in tenant quality, income stability, and very low vacancy and arrears risk. For an investor who prioritizes predictability over performance, it is a coherent allocation in the context of a lasting shortage.

The risk profile is structurally low: tenants are selected on strict criteria, turnover is limited, and demand far exceeds supply. In return, the gross yield is generally below that of small units or managed residences. This is a positioning choice, not an intrinsic weakness of the segment.

Apartment buildings in mid-sized cities: acquisition discounts meet rising rental pressure

Why the shortage is no longer confined to major metropolitan areas

The housing shortage is often framed as a phenomenon concentrated in large cities. That is an oversimplification. Mid-sized cities, long overlooked by institutional investors, are seeing rental pressure increase under a dual movement: households leaving unaffordable major markets to settle there, and a local rental stock that has not been renewed in years.

In these markets, acquisition prices remain significantly below those of major cities, which mechanically produces higher gross yields at comparable rent levels. Cities such as Saint-Etienne or Limoges post rental yields that investors in Paris have not been able to match locally for years. The apartment block, the classic vehicle for rental investment in mid-sized cities, concentrates these advantages: economies of scale in management, discounted purchase prices, and multiple tenants that limit total vacancy risk. For a detailed comparison of how location dynamics shape returns, our analysis of city centre vs suburbs: which delivers better rental yield? offers useful additional context.

Criteria for distinguishing a genuine opportunity from an artificial market

Not all mid-sized cities are equal. Some markets post attractive yields because demand is real and growing. Others show the same numbers because prices have fallen, not because demand has risen.

The distinguishing criteria are concrete: demographic trends over five years, the presence of an active employment basin or university hub, transport links to major cities, and diversity among prospective tenant profiles. A market where rental demand depends on a single employer or on an ageing population with no renewal in sight is structurally fragile, regardless of whatever short-term rental pressure the headline figures suggest.

What tokenization changes for real estate investment in a housing shortage

Accessing resilient assets without a high minimum ticket

Real estate investment in a housing shortage has long been the preserve of those who could mobilize tens of thousands of euros, or more, to access quality assets in high-demand areas. Tokenization fundamentally alters this access dynamic.

By converting rights over real physical property assets into fractional digital bonds, tokenization enables an investor to take a position in an apartment building in a mid-sized city, a student residence in Rennes, or a Parisian coliving asset for a few thousand euros. In doing so, it opens access to asset types that are structurally suited to the shortage, without requiring the capital that was previously the main barrier to entry.

Digital bonds confer rights over the income generated by the asset, whether distributed rental income or margins from short-cycle operations, depending on the nature of the project. They do not confer rights over the value or capital appreciation of the underlying property: this is a debt instrument, not an equity stake. That legal clarity is a protection for the investor as much as it is a framework for predictable returns.

Diversifying by asset type rather than by geography: the Shelters approach

Geographical diversification is often presented as the first instinct of the real estate investor. It has its merits. But in a shortage environment, diversification by asset type is at least as relevant: a portfolio combining a short-cycle property trading operation, a student residence with intermediate yield, and a rental apartment building in a mid-sized city provides exposure to distinct return mechanisms, with different durations and risk profiles.

Shelters builds its offering around this principle. Every operation on the platform corresponds to an identified asset, with a defined duration, a target return stated upfront, and an explicit income mechanism. Shelters co-invests in each project alongside its users, which structurally aligns its interests with those of investors. This is not a matchmaking service: it is a shared commitment on every asset.

Choose your asset before you choose your location: the order of priorities in 2026

The housing shortage creates favorable market conditions for rental investment. But that advantage is not uniform. It rewards assets with structurally captive demand, formats suited to regulatory constraints, and acquisition prices that have not yet fully absorbed the tension premium.

Student residences in mid-sized university cities, coliving in dense urban areas, apartment buildings in mid-sized cities with positive demographic momentum: these are the formats that currently offer the best balance between yield and resilience for real estate investment in a housing shortage.

The decision on the future of rent regulation expected in late June 2026 will shift some of the parameters for major cities. The gradual withdrawal of private landlords continues to feed supply pressure. And mid-sized city markets are waking up faster than prices have yet reflected.

Shelters provides access to these assets on a fractional basis, with an accessible minimum investment, full transparency on every operation, and a clear regulatory framework. For an investor who wants to position in resilient real estate without locking up large amounts of capital, it is a concrete entry point into the market as it stands in 2026.
