Multifamily documents we process

If a human can read it, Primer can extract it.

Rent Rolls

Unit numbers, bed/bath types, SF, current rent, market rent, lease dates, move-in dates, and tenant names from any format.

T12 Financials

Month-by-month income and expenses, NOI, vacancy loss, concessions, and operating expense line items mapped to your chart of accounts.

Offering Memoranda

Property details, unit mix, pro forma assumptions, market comps, and seller projections extracted from broker OMs and BOVs.

Market Comps

Comparable property rents, occupancy rates, amenities, and vintage from CoStar, Yardi Matrix, or broker comp sets.

Yardi & RealPage Exports

Native exports from Yardi Voyager, RealPage OneSite, Entrata, AppFolio, and other property management systems.

Budget vs Actuals

Variance analysis between projected and actual performance, CapEx tracking, and renovation cost reconciliation.

Why multifamily underwriting is different

High unit counts, multiple income streams, and value-add complexity require specialized extraction.

01

Unit mix complexity at scale

A 300-unit property has dozens of floor plans, varying rents by unit type, and different lease terms. Primer normalizes rent rolls from any broker format and groups by bed/bath automatically.

02

T12 vs. Pro Forma reconciliation

Trailing actuals rarely match broker projections. Primer compares T12 income to OM pro forma, flags discrepancies, and lets you model your own assumptions with data from both sources.

03

Multiple income streams

Beyond base rent: parking, pet fees, RUBS, storage, laundry, amenity fees, late fees. Primer extracts each line item separately so you can model ancillary income growth independently.

04

Value-add vs. stabilized analysis

Renovated units command premiums. Primer tracks in-place vs. market rent by unit, calculates loss-to-lease, and identifies unrenovated units so you can model your value-add thesis accurately.

Questions.

How accurate is the extraction?

We maintain 98%+ accuracy by combining AI with deterministic validation rules. The system flags low-confidence fields for human review, so bad data never reaches your model.

98%+ Accuracy
Rent Roll 100% Match
T-12 Expenses 98.4% Match
OM Data 97.8% Match

Does it work with my Excel model?

Yes. We map to YOUR existing Excel template during a one-time setup. Data flows directly into your format.

"Borderline deals used to get deprioritized. Now we send them to Primer. We've put in offers on deals we probably would've passed on."
