Ground-up multifamily & mixed-use development

Underwriting that builds the deal with you — and shows its work.

A verified development-underwriting engine and a team of expert agents that compose the moves to make an attainable, regenerative project pencil. Every number is the engine's; every assumption carries its source.

A proforma is a hope. Underwriting is how you protect the project.

A development proforma tells you what a deal could be. It rarely tells you which moves actually create the value, whether the thing truly pencils, or who's accountable for each assumption. Now City Leverage turns the spreadsheet into a space you can feel your way through — and a set of experts who reason it toward a deal that works, out loud.

Two layers. One that's auditable, one that's smart.

The hard separation is the whole point: the math is fixed and verifiable; the intelligence sits on top of it and never reaches inside.

The engine — the single source of truth

A deterministic pro forma: same inputs in, same numbers out, verified number-for-number against the original underwriting model and guarded by tests. This is the part you can hand to a lender. It contains no judgment and no surprises.

The agents — a value-creation team

Expert agents — building program, cost, revenue, operations, and a capital-stack architect, led by an underwriter — propose the moves and compose the path to "it pencils." They never do the math. They only ever propose assumptions, each clamped to safe bounds and tied to its source.

From a site to a deal that pencils, in three moves.

1

Start from the site

Begin with an honest base case — the program, the costs, the financing — calibrated to real market comps.

2

Drive it, or hand it over

Move the levers and watch every number recompute instantly — or hand the wheel to the agents and watch them reason the deal upward, move by move.

3

Get something defensible

A full underwriting — sources & uses, returns, debt, the program — with every assumption's source, confidence, and author on the record.

It creates 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 Leverage is a development tool: it composes the moves that make a ground-up project work.

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 builds the deal

  • Composes the moves that make a ground-up project pencil
  • Attributes who created which value, step by step
  • Five specialists + a coordinating underwriter
  • Answers "what do we build, and how do we make it work?"

Built on the Now City stack.

Four ways to create value beyond a conventional proforma — each one an expert agent, each grounded in real levers.

Industrialized construction

Efficient building types and disciplined delivery — more home, less basis.

Green infrastructure

Leaner operations and on-site energy that the building earns back.

Regenerative placemaking

A designed, amenity-rich district that the market pays a premium for.

Innovative finance

The full incentive stack — TIF, LIHTC, HUD, NMTC, OZ, C-PACE — composed as one.

Defensible by design.

Nothing here is a black box. The math is verified and auditable; a hallucinated number can never become a result, because the engine — not the model — computes every outcome, and every assumption an agent proposes carries its source, confidence, and author. The kind of underwriting you can take to a lender or an LP.

Your next project deserves real underwriting.
