About

SFR Portfolio Builder exists because 1031 exchange investors are asked to make six- and seven-figure decisions under a 45-day identification window, usually with a spreadsheet, a generic calculator, and whatever numbers happen to be in the offering memo.

We built a tool that automates the financial underwriting of single-family rental investment properties: AI extraction from property description pdf files, a rules-based Fiduciary Filter that scores every deal against your own investment criteria, and 30-year projections grounded in per-market assumptions. The result is the same rigor an institutional acquisitions team would apply, available to any self-directed investor.

This is not a generic real estate calculator, and it is not a curated deal platform. It is built specifically for investors identifying single-family rental investment properties inside a 1031 exchange, and for the sponsors and syndicators who need a repeatable, auditable underwriting workflow for their clients.

SFR Portfolio Builder is currently in early access. Access is private and data is isolated per account.
