Under the hood

From a messy deal room to a populated, cited model.

Upload the full package as it arrives. Primer pulls rent, unit, and operating data from OMs, rent rolls, T-12s, and broker packages, whether they come as PDFs, Excel exports, or scanned images.

Meridian Gardens — Deal Package
PDF Offering Memorandum 42 pages Done
XLS Rent Roll — 128 units Done
SCAN Trailing 12 Scanned PDF OCR

Every populated cell links back to the document, page, and table it came from. When the OM says vacancy is 5% and the T-12 implies 5.8%, Primer flags the conflict and surfaces both figures.

Conflict — Vacancy rate differs

OM p.22

Vacancy: 5.0%

T-12 p.3

Vacancy: 5.8%

The broker calls it "extermination," your chart of accounts says "pest control." Primer learns your label mapping once and applies it automatically on every deal after that.

Pest Control/Extermination → Pest Control
R&M - General → Repairs & Maint.
Landscaping & Snow → Grounds Maint.

Beyond the model

One deal populates more than a model.

Every deal builds a shared comp database and generates a full investment memo in your firm's format.

Comp Database

Every deal builds your comp library.

Rent comps, sales comps, and expense comps are tracked automatically from broker documents and third-party data sources. Search across every deal your team has processed, filter by market, and view everything on a map.

Investment Memo

Your investment memo, built automatically.

Primer generates a complete investment memo as a PowerPoint deck in your firm's template. Executive summary through risk factors, populated from the deal data already in the system.

Due diligence

What teams ask before getting started.

Primer combines AI extraction with deterministic validation rules. Every output includes confidence indicators, and low-confidence fields are flagged for analyst review before reaching your model.

Most teams are processing live deals within the first week. We map your existing Excel model during onboarding and handle the initial template configuration.

Data is stored on SOC 2 compliant infrastructure. We never train models on your data. Each client operates in an isolated tenant environment with no cross-visibility.

General-purpose AI tools cannot maintain your chart of accounts across deals, build a persistent comp database your team shares, or deliver a populated Excel model with every cell cited to source. Primer handles all three as part of one workflow.

Most of our customers said the same thing before starting. Primer removes the manual data entry inside your existing process. Same model, same judgment calls. Your team just stops typing numbers from PDFs.

Boardwalk Storage tripled their underwriting capacity. LRE Management cut per-deal time from 1.5 hours to 10 minutes. The value compounds as your comp database grows and your template mappings cover more deal types.
