Instant Leases
Secure more leases, with less work.

Boost operational efficiency and improve the renter experience with a streamlined leasing journey—from application to signature.
Instant Leases—powered by Building Stack—streamlines the leasing process for teams of all sizes, from independent landlords to large multifamily portfolios.
In a competitive rental market, speed matters. But so does easing the burden on leasing agents. Instant Leases is built to eliminate manual back-and-forth, reduce friction for prospects, and close deals faster, without sacrificing the human touch.
Its real strength? Driving early commitment. By collecting key details like banking information, credit checks, and rent deposits upfront, Instant Leases keeps prospects engaged and less likely to shop around. That means fewer lost opportunities—and more signed leases, faster.
