The Deal Looks Good. Until You Stress-Test It.
Solsten helps you pressure-test a deal before you submit the offer. Every assumption is versioned, every number traces back to its source, and the same deal you modeled six months ago still ties out today.
Most CRE deals don’t fail because of one bad number. They fail when assumptions start moving.
Solsten is built to expose the weak points before you get emotionally attached to the deal. If the assumptions bend, you want to know which one breaks first.
Vacancy drift
A deal can look fine on day one and still miss hard when rollover, renewal probability, and downtime stack up across the hold period.
Insurance and expense creep
Small assumption shifts in taxes, insurance, or recoveries can move cash flow more than a lot of people expect. That’s where the hidden bleed usually starts.
Exit cap compression
If your exit assumptions are too optimistic, the deal can lose most of its upside long before the sale date arrives.
Close the Excel Gap Before the Deal Closes You
ARGUS charges $3,000–$10,000 per seat. Excel spreadsheets break silently. Solsten is a purpose-built CRE underwriting engine that gives you institutional-grade analysis at a fraction of the cost — plus AI guidance grounded in your actual assumptions, timelines, and results.
