02 — Why brokers send us their deals

You’re not hiring a vendor. You’re getting a team.

Underwriting, content, and design — cross-trained specialists who work your deal together, run it through multiple internal review rounds, and hand you a finished product.

01

Institutional by default

Every page is built to the standard buyers expect from the big shops — the credibility a listing earns before a word is read.

02

Specialists who cross-train

Underwriting, content, and design each own their craft and cross-train across the others, so nothing falls between the seams. A project manager owns your account.

03

Reviewed before you see it

Every deliverable runs through multiple internal review rounds and a senior sign-off. You approve a finished product — never the one catching the errors.

04

Confidential, US-based, in-house

We sign your NDA on every engagement; your deal and data are never shared, reused, or sent offshore. A small, senior, in-house team — no subcontractors.

03 — Argus & Excel underwriting

An OM is only as good as its underwriting.

Send us your model and we’ll build the OM around it — or have us underwrite the deal from scratch. Either way, the numbers and the story hold up to an institutional buyer.

  • Full institutional models. Rent rolls and T-12s normalized, a multi-year proforma, financing, and returns — work you can hand to a committee.
  • Every asset class. Argus & Excel cash-flow models, debt, and sensitivities across multifamily and commercial.
  • Your model or ours. Standard institutional exhibits, or built straight into your template.

Questions

Good questions, answered.

How fast will I get my OM?
Most OMs are delivered in three to four business days; shorter Essential OMs are often ready in two to three. Add-on underwriting can add a day. You’ll see a turnaround estimate the moment you price your deal, and if we ever expect to miss it, you’ll hear from us on day one — not day four.
Is my deal kept confidential?
Always. We sign your NDA on every engagement. Your materials, data, and the existence of the deal are never shared or reused, and work is handled by a small, senior, US-based in-house team — no offshore, no subcontractors.
What do you need from me to start?
As little as an address. Ideally a rent roll and a T-12 (or your underwriting) so we can build accurate financials — but if you only have the basics, we’ll tell you exactly what would strengthen the OM.
How many revisions are included?
We revise until it’s right. Full-service OMs include a deeper content pass and an extra dedicated revision round; every tier is refined with you until you’re ready to take it to market.
Can you use my brand or template?
Yes. We’ll apply your company branding for a one-time $90 setup on your first OM, or build into your own template. Prefer a bespoke design? We’ll commission one — no charge to submit and discuss.
Why is it less than the national shops?
Because we’ve automated the busywork — formatting, data entry, layout production — not the judgment. Senior people still underwrite the deal, write the narrative, and sign off on every page. You get institutional quality without paying for institutional overhead.
Is the price really final?
The number you see when you price your OM is the number you submit at. No quote calls, no scope games — a clear price before you commit, and you approve the work before any payment.
