The Roommate Compatibility Report 2026

Compatibility is not one thing. It is a stack of smaller decisions that either support the home or slowly wear it down.

This report summarizes an anonymized CoHabby sample of 100 `synergy_scores` documents and 200 user profiles to show which matching dimensions are strongest, where fit is weakest, and what the current marketplace is signaling.

What the sampled data suggests

The current CoHabby sample points to a useful tension: personality and lifestyle alignment look relatively strong, while housing alignment remains weaker. That means the hard problems in shared housing are often not just who the person is, but whether the actual setup can support the match.

In practical terms, better matching content should keep pushing on commute fit, guest expectations, room setup, and how shared space is used.

Why seeker-heavy demand matters

The sampled profile set is heavily weighted toward people looking for rooms or housemates rather than offering space. That reinforces the need for deeper lister-funnel SEO in Phase 2 and stronger content for listing creators.

How to read this report correctly

This is an aggregate sample snapshot, not a universal claim about every renter or every room listing. It is most useful as directional insight: what appears strong, what appears weak, and where CoHabby’s current match data says attention belongs next.
