Who Really Bears the Risk in Homeownership? It's you.

Buying a home is the largest leveraged bet most Americans will ever make. It is also, remarkably, a bet whose risk structure has gone essentially unquestioned for nearly a century. The 30-year fixed-rate mortgage was invented 88 years ago and has become so deeply embedded in American life that we've stopped noticing how much risk it concentrates on the one party least equipped to bear it: the homeowner.

At Ownify, we've built a fractional ownership model that disaggregates these risks and redistributes them between the homeowner and an institutional co-investor. The result isn't just a different financing product, it's a fundamentally different risk architecture for residential real estate. 

In April of 2026, I was lucky enough to be invited to a brown-bag luncheon at the SF Federal Reserve. This blog post was triggered by the the conversation with Amir Kermani from UC Berkeley and Michael Bauer from the SF Fed (those guys write peer-reviewed research papers. Alas, I write blog posts)...

This post walks through the seven major financial risks of homeownership, examines who bears each one under the traditional mortgage model, and explains why a co-ownership structure - as distinct from the "shared equity" products currently on the market - is the only structure that delivers genuine risk transfer.

1. Market Risk (Depreciation)

In the traditional mortgage-financed model, the homeowner absorbs 100% of price declines (and also benefits from 100% of price appreciation). A lender holding a $380,000 note on a $400,000 home doesn't care if the home drops to $350,000, the borrower is still on the hook for the full balance. With a typical 5% down payment, even a modest 10% decline in home value wipes out all of the buyer's equity and puts them underwater. In severe downturns (think Las Vegas in 2009, down 55% from peak) the borrower's loss can exceed their entire original investment many times over, while the lender's position is insulated by mortgage insurance (which the borrower paid for) and the GSE insurance mechnism (which tax payers ultimately finance).

The magnitude here is not theoretical. National home prices fell 27% peak-to-trough in the Great Recession. Regional declines of 40–60% are within living memory.

In a co-ownership model, market risk is shared proportionally. If the home declines in value, both parties (Ownify as an institutional investor and the homebuyer) absorb the loss in proportion to their ownership stake. A buyer who owns 10% of the home is exposed to 10% of any price decline, not 100% of it through a leveraged position. And critically, because there is no mortgage debt, the concept of being "underwater" doesn't exist. You can't owe more than the home is worth when you don't owe anything. You simply own a fractional share of whatever the home is currently worth.

This is genuine risk transfer. The institutional co-investor, who is diversified across many properties and has a longer time horizon, takes on the majority of the market exposure - which is exactly where that risk belongs from a portfolio theory perspective.

2. Leverage Risk

In the traditional model, the mortgage is, structurally, a leveraged bet. A buyer putting 5% down is levered 20:1 on their equity. At 3.5% down (the minimum for FHA loans), it's 29:1.

To put that in context: the average leveraged buyout in private equity runs at roughly 5:1 to 7:1 debt-to-equity. These are deals structured by professionals with dedicated risk management teams, access to hedging instruments, diversified portfolios, and the ability to actively manage their investments. A first-time homebuyer putting 5% down on a single property with no diversification, no hedging capability, and no institutional risk infrastructure is levered at 3–4x the ratio of a typical PE buyout. At 3% down, it's nearly 5x the leverage of a PE shop. These are leverage ratios that would raise eyebrows in the most aggressive corners of institutional finance, yet they're standard consumer products marketed to 28-year-olds buying their first home. 

This leverage amplifies gains in a rising market, which is why homeownership "feels" like a great investment when prices go up. But it also amplifies losses catastrophically. A 10% home price decline on 5% down doesn't just erase the buyer's equity — it puts them at negative 100% return on invested capital.

In Ownify's co-ownership model there is no consumer leverage. There is no debt. The buyer contributes capital (starting at 2% of the home's value) and owns a corresponding fraction of the property. The relationship between the buyer's investment and their exposure is 1:1, not 20:1. If the home appreciates 10%, the buyer's fractional stake appreciates 10%. If it declines 10%, they lose 10% of their invested capital - not 200% of it. 

Eliminating leverage doesn't eliminate risk, but it makes risk proportionate and survivable. This is the difference between an investment that can go to zero and one that can go to negative multiples of your original stake.

Now, the counterpoint I often hear from real estate professionals is "but the consumer should get 100% of the upside". That misses the point. If you can afford to bear the risk of a 30x levered investment, and you are a 100% informed consumer, then godspeed. After all, it's a free country (and you have ~900 pages of mortgage disclosures making sure you bear those risks). However, most consumers aren't fully aware of the risk/return tradeoffs and the magnitude of the downside. The value proposition of co-ownership is to reduce the costs of ownership for the first-time buyer by using shared upside as a vehicle to subsidize those costs. 

3. Interest Rate Risk

In the traditional model, mortgage borrowers bear interest rate risk in two ways. First, the direct payment risk: borrowers with adjustable-rate mortgages face potentially severe payment shocks. A 3-percentage-point rate increase on a $350,000 balance adds roughly $700/month to the payment - enough to push a household from comfortable to distressed. Second, even fixed-rate borrowers face an indirect form of rate risk: when rates rise, home values tend to fall (since the same monthly payment buys less house), which compounds market risk. And when rates fall, the borrower can only capture the benefit by refinancing - a transaction that costs $3,000–$6,000 and requires re-qualifying.

Ownify's co-ownership model: Because there is no mortgage, there is no interest rate to fluctuate. The buyer's monthly payments are fixed for the program term (typically five years). Rising rates don't change the homeowner's cost of occupancy, and falling rates don't create a refinancing decision. The institutional co-investor bears the cost-of-capital risk associated with funding the property, which is appropriate given that institutional investors have access to hedging instruments, diversified funding sources, and the balance sheet to absorb rate volatility.

This is perhaps the cleanest example of risk transfer in the model: a risk that is existential for an individual household is routine for an institutional capital provider.

4. Liquidity and Transaction Cost Risk

A home is one of the most illiquid assets an individual can own. Selling takes 2–6 months and costs 6–10% of the home's value in agent commissions, closing costs, repairs, staging, and concessions. This means a homeowner needs roughly 10% cumulative appreciation just to break even after transaction costs. If life forces a sale - job relocation, divorce, medical emergency - the homeowner cannot exit quickly, and the transaction costs function as a punitive exit fee.

How "shared equity" products handle this - and don't: This is an area where it's important to distinguish between Ownify's co-ownership model and the Home Equity Investment (HEI) or Shared Equity second mortgage products products currently on the market.

In a typical HEI contract, the investor's settlement amount at sale is calculated based on the appraised or gross sale value of the home - not the net proceeds after commissions and closing costs. The homeowner pays 5–6% in agent commissions, 1–2% in closing costs, and whatever other selling expenses arise, and then the HEI company takes their percentage of the home's value on top of that. The investor's return is entirely insulated from transaction costs; the homeowner absorbs all of them.

Consider a concrete example: a homeowner sells a $400,000 home with $24,000 in total transaction costs (6%). An HEI investor with a 10% stake collects $40,000 based on the gross value. The homeowner's actual proceeds are $400,000 minus $24,000 in transaction costs minus $40,000 to the investor = $336,000. The investor bears zero transaction friction. The homeowner bears all of it. This is not "shared" anything.

Ownify's co-ownership model: The fractional ownership structure provides flexibility that a mortgage does not. The buyer can increase their ownership stake over time (buying more "bricks," in Ownify's terminology) or, at the end of the program term, choose to buy out Ownify's share with a traditional mortgage, or sell their equity stake back at a 2% transaction fee. The lower transaction cost means less is at stake if circumstances change early. 

The liquidity risk doesn't disappear - the underlying asset is still a house - but the buyer's financial exposure is right-sized to their actual commitment horizon rather than locked into a three-decade structure.

5. Repair and Capital Expenditure Risk

Traditional model: Homeowners are responsible for 100% of maintenance and capital expenditure, typically estimated at 1–2% of home value annually. But this average masks enormous variance: a new roof ($15,000 - $25,000), HVAC replacement ($5,000 - $12,000), or foundation repair ($10,000 - $30,000) can hit without warning (we have done all of those for homes in the Ownify portfolio). These costs are lumpy, unpredictable, and entirely the homeowner's problem. There is no landlord to call, no maintenance reserve funded by someone else, and no insurance that covers normal wear and tear.

Ownify's co-ownership model: during the Ownify program, major repairs are covered by Ownify (and effectively defrayed through portfolio diversification). At the same time, standard maintenance is the responsibility of the resident, benefiting both parties. The structure aligns the co-investor's incentive to protect the property's value with the homeowner's occupancy interest. The homeowner is no longer the sole party exposed to a $20,000 surprise.

6. Concentration Risk

Traditional model: For most American households, the primary residence represents 50–70% of total net worth. This is an extraordinary concentration in a single illiquid, leveraged, geographically fixed asset. The risk is compounded by correlation: if the local economy declines, the homeowner may lose their job and their home equity simultaneously. The 2008 crisis demonstrated this at scale - millions of households experienced correlated employment and housing losses, with no diversification to cushion either. Amir Sufi wrote brilliantly about this in his book "House of Debt".

No competent financial advisor would recommend putting 60% of a client's net worth into a single leveraged position in a single asset class in a single geography. Yet that is precisely what the traditional mortgage model encourages - and what federal policy subsidizes through the mortgage interest deduction and GSE guarantees.

Ownify's co-ownership model: The lower capital commitment at entry (2% down versus 5–20%) means less of the buyer's net worth is locked in the home from day one. The buyer can allocate the capital they would have spent on a large down payment to diversified investments - index funds, retirement accounts, emergency reserves - while still building equity in a home they live in. Over time, as the buyer increases their ownership stake, concentration naturally increases, albeit on a timeline and at a pace they control, rather than as a forced all-in bet at the moment of purchase.

For the institutional co-investor, the risk picture is reversed: each individual property is a small fraction of a diversified residential portfolio. Geographic and market concentration risk that is catastrophic for a single household is manageable across a portfolio.

7. Insurance and Catastrophic Risk

In the traditional model homeowners insurance has become increasingly expensive and, in some markets, increasingly unavailable. Premiums in fire-prone, flood-prone, and hurricane-prone areas have doubled or tripled in recent years. Major insurers have pulled out of entire states. Even with coverage in place, rising deductibles and coverage gaps leave homeowners exposed to significant uninsured losses. A total loss event can be financially devastating, destroying both the physical asset and the owner's entire equity position.

In Ownify's co-ownership model, insurance remains necessary, but the co-ownership model changes the exposure profile. As an institutional co-investor we have access to institutional-grade insurance products and risk management. Across our portfolio, we pay about 25% lower rates for P&C coverage than individual homeowners would be able to. That reduces cost to the resident. At the same time, the buyer's maximum loss in a catastrophic event is limited to their fractional ownership stake, not the full value of the property. And because the institutional partner is diversified across many properties in different geographies, the portfolio-level impact of any single catastrophic event is bounded.

The Structural Argument

What connects all seven of these risk categories is a single structural observation: the traditional mortgage model concentrates virtually every form of housing risk onto the individual homeowner, while the parties best positioned to bear those risks - institutional investors with diversified portfolios, long time horizons, and access to hedging tools - are largely insulated from those risks (but also unable to participate in the upside).

Mortgage lenders earn gain on sale fees on a secured loan, protected by mortgage insurance (which the borrower pays for), government guarantees, and the ability to securitize and sell the risk. The real estate agent earns a commission regardless of whether the buyer's investment appreciates. The government backstops systemic risk through the GSEs, socializing losses across all taxpayers. The homeowner absorbs market risk, leverage risk, interest rate risk, liquidity risk, maintenance risk, concentration risk, and catastrophic risk - levered at ratios that dwarf a typical PE buyout - and is told this is the American Dream. This all works well while home prices appreciate 5% per year but has gotten much harder to defend recently.

Ownify's co-ownership model doesn't eliminate risk from homeownership. Risk is inherent in owning real property. What it does is redistribute risk according to capacity: moving market and leverage risk toward institutional investors who can diversify across hundreds of properties, shifting interest rate risk to capital providers who can hedge it, and reducing concentration risk for households by lowering the required capital commitment.

This isn't charity and it isn't magic. The institutional investor participates in the upside of home price appreciation in exchange for bearing a proportional share of the downside. The homeowner gives up some of the leveraged upside of a traditional mortgage in exchange for a dramatically more survivable risk profile. Both parties are better served by a structure that matches risk to the party best equipped to bear it.

In finance, this is called efficient risk allocation. In housing, it's called a new idea. It shouldn't be.
