What We Extract

Every document in your deal package

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

Rent Rolls

Unit-level data: unit number, size, type (climate/non-climate), current rate, move-in date, and occupancy status.

Unit Mix Summaries

Aggregated counts by unit type, net rentable SF, average rate per unit type, and occupancy by category.

Street Rate Sheets

Current asking rates by unit size for ECRI analysis. Compare street rates to in-place rates to model upside.

T12 Operating Statements

Trailing 12-month revenue and expense data, including ancillary income (retail, insurance, truck rentals).

Competitor Comps

Market rate data from Radius+, Yardi Matrix, or broker comps. Extracted and standardized for comparison.

Management Exports

Reports from SiteLink, storEDGE, Easy Storage, or any property management software. Any format, any export.

Why self-storage underwriting is different

Month-to-month leases, ECRI strategies, and unit type complexity require specialized extraction.

01

ECRI is the growth engine

Existing Customer Rate Increases drive 60%+ of revenue growth. Primer compares in-place rates to street rates by unit type to quantify your ECRI opportunity—the key metric lenders and investors scrutinize.

02

Unit type chaos

15+ unit sizes, climate vs. non-climate, drive-up vs. interior, parking vs. RV. Primer normalizes inconsistent naming conventions ("CC", "heated", "temperature-controlled") into your standard categories.

03

Month-to-month dynamics

Unlike annual apartment leases, self-storage is month-to-month. Average length of stay now exceeds 17 months, but churn patterns vary by market. Primer extracts tenant tenure data for accurate revenue modeling.

04

Ancillary income matters

TPP (Tenant Protection Plans), retail sales, truck rentals, and admin fees can represent 10-15% of revenue. Primer extracts each line item separately so you can model ancillary growth independently.

Questions.

What property management systems do you support?

Primer works with exports from SiteLink, storEDGE, Easy Storage, Yardi, and any other PMS. We also handle PDFs, scanned documents, and Excel files. If you can export it, we can read it.

How do you handle portfolio deals?

Primer processes each property in a portfolio separately, then rolls up to portfolio-level summaries. You get property-level detail and portfolio-level aggregates in one extraction.

Can you extract competitor rate data?

Yes. Primer extracts rate data from Radius+, Yardi Matrix reports, and broker comp sheets. We standardize by unit size and type for direct comparison.

What about boat/RV and outdoor parking?

Primer handles all unit types: traditional storage, boat/RV, covered parking, outdoor parking, and wine storage. Each gets categorized and extracted with the right metrics.

"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."
