The numbers have not gone back to where they were. Anyone waiting for a meaningful drop in rates or prices in coastal urban markets is making a longer bet than most people who need to buy a home can actually hold. What has happened instead is that buyers have adapted, and one of the most visible adaptations is buying with someone else.
At Rhome we see this clearly. Most of the groups coming through our platform in the first half of 2026 are first-time buyers who could not get there alone but can get there together. The calculation is often surprisingly clean: two buyers with moderate incomes and combined down payment savings can qualify for a home that neither could approach on their own.
The affordability mechanics behind co-buying
A conventional lender evaluating a solo buyer at $75,000 annual income applying for a $480,000 loan at 7% is looking at a roughly 50% debt-to-income ratio including the new mortgage. That is above standard approval thresholds for most loan programs. Two buyers at $65,000 each present combined income of $130,000. The same loan now represents a 30% DTI. Approved.
The down payment side matters just as much. In many South Florida markets, a 10% down payment on a $450,000 home is $45,000. For one buyer, that can mean years of saving. For two buyers each contributing $22,500, the timeline compresses considerably. The numbers are not magic; they reflect that two people together can often reach a threshold that one person cannot reach alone, and lenders underwrite accordingly.
Co-buying also changes what buyers can afford in terms of location and property type. A solo buyer who could realistically qualify for a two-bedroom in a suburban area may co-buy a property in a walkable urban neighborhood that better fits how they actually want to live. That is a different kind of optionality than affordability alone suggests.
What shifted in 2025 and into 2026
Co-buying is not new. What changed is that it has moved from a niche workaround into a considered first-choice strategy for a meaningful slice of buyers. Several things drove that shift.
First, the rental math got worse. In many markets, monthly rent on a two-bedroom has converged with or exceeded a co-buying mortgage payment split between two people. When renting together costs as much as owning together, the calculus changes. Renters who were previously deferring the purchase conversation are now running the numbers seriously.
Second, buyers are more aware that tools exist to help groups structure the purchase. Three years ago, most buyers thinking about co-buying had to figure out the ownership agreement, the equity split, and the exit terms entirely from scratch or with an attorney starting from zero. That is less true now, and the lower friction means more people are completing the conversation rather than abandoning it at the first complexity.
Third, the supply environment in desirable neighborhoods rewards buyers who can move quickly with a solid qualification. A group with a combined pre-approval at a meaningful price point is often in a stronger offer position than a marginal solo buyer at the same price. This is a real competitive dynamic, particularly in Miami neighborhoods where inventory moves quickly.
Where co-buying goes wrong
We are not saying co-buying is the right path for every pair of buyers who can clear the DTI math together. The financial eligibility is genuinely the easy part. The hard part is what comes after closing.
The groups that get into trouble share a consistent pattern: they structured the purchase but not the ownership. They agreed on a price, got approved, split the down payment, and signed a mortgage. They did not write down what happens if one person needs to relocate for work in 18 months. They did not agree on whether either party has a right to buy out the other, and at what valuation. They did not decide who has final say on a major repair decision.
These are not exotic scenarios. A job change, a relationship shift, a financial setback, a career move across the country: these are events that happen over a five-to-eight year ownership window. When nothing is written down, each event becomes a negotiation from scratch against the backdrop of a shared asset and a joint legal obligation on the mortgage.
The co-ownerships we see functioning well after a few years are the ones that treated the agreement structure with the same seriousness they brought to the loan application. The groups that view the exit clause as paperwork to rush through are the ones more likely to call us later with a conflict that could have been avoided with a two-page document drafted before closing.
What the structure actually costs
Some buyers assume that properly structuring a co-ownership is expensive or complex. In the context of the transaction it is neither, and the cost-benefit comparison is not close.
An attorney-drafted co-ownership agreement in Florida typically runs between $800 and $2,000 depending on complexity and attorney experience with property co-ownership specifically. Against the cost of the transaction, that is a small fraction. Against the cost of a legal dispute over an unresolved exit situation (which can run into five figures before it resolves), it is minimal.
Rhome's role is to build the framework before attorney review. We calculate the equity split, structure the payment responsibilities, and draft the exit terms. What a group takes to their attorney is a structured starting document rather than a blank page, which reduces review time and typically keeps costs at the lower end of the range.
The 2026 co-buyer profile
The buyers co-purchasing right now are not mostly people who cannot afford anything else. Many of them could buy alone in a cheaper market or at a lower price point. They are choosing co-buying because it gets them into the market they actually want, on a timeline that makes sense, with a structure that protects both parties from the scenarios that cause most co-ownership disputes.
That is a different framing than co-buying as a last resort. It is co-buying as a deliberate strategy. A pair of buyers in their late twenties in Coconut Grove, each putting in $30,000 and splitting a $550,000 property, who have a written equity split and exit clause: that is a group that went into this with their eyes open. The ownership document is not a signal of distrust in each other. It is a signal that they both understand what they signed up for.
The version of co-buying that becomes more common in the years ahead is the version where buyers treat the ownership structure with the same intentionality they bring to the property search itself. The math will keep supporting it. The question is whether the structure around it keeps pace.
