About · DealProp
DealProp is software for the people the property-management industry skipped.
DealProp started in a small town. Watching the neighbors who own rentals work three jobs to keep up with them — one for the day job, one for the bookkeeping, one for the late-night maintenance calls — made it obvious that the property- management software industry had skipped a step.
Buildium and AppFolio sell complexity to enterprise operators. Stessa and TurboTenant top out somewhere around door five. Between those two ends sits the actual majority of the U.S. rental market: small landlords with too many doors for a spreadsheet and not enough doors for an enterprise platform. That gap is where DealProp lives.
“I live in a small town where landlords run rentals on spreadsheets and paper. The enterprise platforms sell complexity to 1,000-unit operators. The DIY tools stop being enough at door five. I built DealProp because someone with 12 doors deserves the same automation a 1,200-door operator gets — without the complexity, without the 18-month rollout, and at a price that fits the smaller scale.”
The same philosophy scales: 50 doors, 200 doors, 1,000 doors all get the same simplicity — just with more rows. DealProp is built for the small operator who wants room to grow, and for the larger operator who is tired of being sold complexity.
Three principles. They show up in every feature, every screen, every default.
Every feature has a 30-second path to value. We measure setup time and clicks-to-done, not feature count. If something needs a manual, we redesign it.
Rent collection, repair dispatch, books. The repeatable parts. We do not automate the parts that need your judgment — vendor selection, lease decisions, owner relationships. Software should hand you back time, not take away authority.
CSV export on request. No lock-in. No exit fee. We never sell your data, your tenants’ data, or aggregated insights. Ever. The whole business model is your subscription and the platform fee on rent — nothing else.

David Perez is the founder of Cortex Automations, the engineering studio behind DealProp. He built DealProp after watching landlords in his small town run rental businesses on spreadsheets and shoeboxes of receipts — and seeing that the platforms selling complexity to 1,000-unit operators didn't fit the rest of the market.
Small team. No venture funding. No five-year plan to be Buildium. The roadmap is what landlords ask for; the bar is what their accountants and tenants expect. DealProp is built the way David would want software to handle his own money.
The next ship is the AI maintenance + vendor dispatch UX — turning the backend wedge into the surface every PM and landlord touches at 11 p.m. when a tenant texts about a leak. After that: lease management, an owner portal, and the slower payment-rail migration that takes effect once a critical mass of PMs are running on the platform. The pace is steady; the principles do not change.
Software that handles other people's money should be held to their standard.
