The model and the backup belong on the same deal

Most shops still keep the model in one workbook, the rent roll in a shared drive, and the reason a Phase I was waived in someone's inbox. When the IC packet is due, someone rebuilds the story by hand. REIN is built so that work never leaves the deal.

The pipeline is five stages: sourcing, LOI, due diligence, under contract, and closed. Each stage opens its checklist. Sixty-seven items ship with the book. Forty-six of them expect a document. Completing one of those without a file requires a reason, and that reason stays on the record.

Underwriting is not a screenshot of a spreadsheet. Cap rate, DSCR, LTV, debt yield, cash-on-cash, and levered IRR sit on the same inputs. A three-year cap on a five-year hold shows the two years that sit uncovered. You can pull figures from a filed rent roll or operating statement, or type them. Saving a model versions it against the deal.

The data room is not a dump. A PCA belongs on the task that asked for it. Rename the deal and the file stays attached. Counsel or a lender can receive a read-only share link that expires. They do not need an account.

REIN is built by FlowTasks LLC and runs on Cloudflare. Signup starts a fourteen-day Professional trial. No card. The desk is the product: underwrite the deal, keep the evidence.
