The Underwriting Playbook for Serious Multifamily Investors
Underwrite Like the Pros.
In Minutes, Not Spreadsheets.
Multifamily Locker Room replaces your fragile, error-prone Excel underwriting model with a professional-grade underwriting calculator built by underwriters, for underwriters. Run full deal analysis — NOI, cap rate, DSCR, cash-on-cash, IRR, equity multiple, and GP/LP waterfalls — right in your browser, from your phone or laptop, in the field, before your competition finishes opening their spreadsheet.
No spreadsheet. No formulas to break. No more #DIV/0! at 11pm before an LOI is due.

You Know This Pain
Excel Wasn't Built for Deals Moving This Fast
One broken cell breaks everything.
A single bad formula cascades into #DIV/0! errors across your entire IRR and equity multiple — and you don't catch it until you've already sent numbers to your LP.
You can't underwrite from a rent roll walkthrough.
Real deals get sourced on-site, at the property, on your phone — not back at a desk with a laptop open.
Every underwriter builds their own template — and it shows.
No standardization, no version control, no way to trust the model you inherited from the last analyst who touched it.
Multifamily Locker Room fixes all three.

GP/LP Waterfall
Preferred return, catch-up, and equity splits at exit — modeled the way real syndications are structured.
