Stack is a tenant app with one job: make as many tenants as possible tap a single button. They extend their lease and get paid instantly. You get higher rents, less churn, and zero renewal overhead.
30 minutes. Bring your unit count and your gut feel on turnover. We'll show you the math.
Renewals have been manual, adversarial, and expensive for the entire history of the rental industry. Stack turns them into an automated, tenant-initiated, profitable event. Every other PM platform digitized the paperwork. We redesigned the incentive.
Every tap of the renew button compounds value in three ways that together can add $500K–$1M in NOI to a large building.
200 units × 45% churn × $5,000/turn = $450K/year bleeding out the door. Tenants with accrued cash don't leave over marginal decisions. Cut churn 15% and save $67,500 immediately.
The seed lease encodes a rent escalator. Tenants opt into it voluntarily because there's a check on the other side. The difference between 3% and 4.5% compounding over a hold period is hundreds of thousands in NOI—and millions in building value.
The industry spends ~47.5 hours per unit per year on leasing. That's roughly $2,000/unit in labor—the 90-day notice window, the negotiation, the Docusign chase, the follow-up calls. Stack replaces all of it with a button the tenant presses themselves.
The seed lease defines renewal terms on day one. The app puts a cash incentive in front of the tenant. The button does the rest.
The seed lease defines rent escalators upfront—say 4.5%/year. When the tenant taps renew, rent adjusts automatically. No negotiation, no surprise, no Docusign. Everybody agreed on day one.
Tenants see a "Stay Value" balance growing monthly in the app. It accelerates over tenure: $50/mo in year one, $75 in year two, $100 in year three. The longer they stay, the faster it grows.
At any point, the tenant can tap to extend one year and cash out instantly. Rent escalates, lease rolls forward, money hits their account. Renewal becomes something tenants look forward to—not something you chase them for.
Stack isn't paying tenants to stay. It's restructuring the renewal into a standing offer that tenants pull toward themselves.
$200 today beats $600 in 8 months. Not rational, but human. Tenants claim early and cheap, voluntarily retaining themselves for less than it would have cost to keep them later. Workforce housing tenants—the highest-churn segment—are the most responsive.
An accruing balance that's forfeited on move-out feels like losing money. The same mechanism that makes people hold airline miles and refuse to abandon vesting schedules. Leaving means walking away from something visible and growing.
Every renewal reveals the tenant's retention price. Claim at month 4 for $200? Cheap to retain. Wait until month 11 for $600? On the fence. Leave without claiming? Uninfluenceable. Over a few cycles you have a retention cost curve no one else in the industry has.
Concessions are reactive negotiations where the tenant has leverage. The standing offer inverts it: money is already there, visible, accruing. The tenant isn't negotiating—they're claiming. Operators never offer a concession again because it's already priced in, structured, and predictable.
When a tenant eventually leaves, they leave with a check. That changes everything about their review.
A tenant who gets paid out on departure has no reason to trash your building online. The check transforms a negative emotional event into a positive one. Your 2-star move-out reviews become 5-star reviews overnight.
Better reviews → lower leasing costs → faster lease-up → less vacancy. It compounds.
Concessions, renovations, and loyalty discounts all try to solve retention. None of them systematize the renewal.
