Ground-up multifamily & mixed-use development

Reveal the value hidden in a development deal.

A living, collaborative pro forma. One person owns the deal. Their partners, and a team of agents each focused on one part of it, propose moves that could make it work better: a lower cost, a rent premium, a different way to finance it. A checked engine runs the numbers, and you can always see where a change came from.

A pro forma is a snapshot. This one is alive, and you build it together.

Normally a development pro forma is a static snapshot that one analyst drives alone in a spreadsheet. It rarely shows which changes actually create value, or where an assumption came from. This one is different. Change any assumption and watch the numbers move, either by hand or with an agent making the change and showing its work, always held against what the feasibility study supports.

Two parts: the calculator, and the agents.

The math is fixed and checked. The agents only suggest inputs. They never change how the deal is calculated.

The engine: one calculator

The same code every run, checked number-for-number against the original underwriting model. Same inputs in, same numbers out. This is the part you can hand to a lender, with no judgment and no surprises.

The agents: they suggest, they don't calculate

A team of agents, each focused on one part of the deal. A dedicated Anchor agent holds the feasibility baseline. Composers cover program, cost, revenue, operations, and financing, and a lead coordinates them. Each proposes changes in its own area, within fixed limits, and saves the source behind each one. The engine does the arithmetic.

From a feasibility baseline to revealed value, in three moves.

1

Start from the baseline

Begin with an honest base case, the one the Anchor ties to the feasibility study. The program, the costs, and the financing, all calibrated to real market comps.

2

Drive it, or hand it over

Move the levers and watch the numbers move with you. Or hand the wheel to the agents and watch them find value, one move at a time, flagging anything that drifts from the baseline.

3

Get something defensible

A full underwriting: sources and uses, returns, debt, and the program. Behind every assumption you can see its source, its confidence, and who put it there.

It reveals the deal. It doesn't just grade one.

Acquisition tools layer a single AI reviewer over a deal you've already shaped. The Now City Upside Explorer is a development tool. It helps you find the value that makes a ground-up project work, and keep working over time, for everyone at the table.

A single AI reviewer

  • Grades an existing, stabilized asset
  • Critiques numbers you already entered
  • One generalist voice over the spreadsheet
  • Answers "should I buy this?"

A team that reveals the value

  • Finds the value that makes a ground-up project work, and keep working
  • Shows who created which value, step by step
  • A team of agents and a lead, anchored to the feasibility study
  • Answers "what do we build, and how do we make it work?"

Why you can trust the numbers.

The math is the same checked code every run. An agent can suggest an assumption that turns out to be wrong, but it can't change how the deal is calculated, and you can always see the source behind what it suggests. That's a number you can take to a lender, not one you take on faith.

Your next project deserves real underwriting.
