How BrickRatio is used in practice
The tool is built for analysts who need a fast answer before they spend thirty minutes inside a spreadsheet.
1
Screen the listing
Enter the headline price, expected rent, and a vacancy rate that reflects the local market rather than the brochure.
2
Pressure-test costs
Adjust operating costs for service charges, licensing, and repairs. Margins usually compress here, not in the headline rent.
3
Decide on next action
Save the output, compare it with financing assumptions, and decide whether the deal deserves a viewing or a revised bid.

Analyst note
“The fastest way to overpay is to underwrite the expenses as if the property will never age.”
Desk comment from this month’s screening logWhat users say
Feedback from investors, brokers, and asset managers using BrickRatio in early-stage review.
Amelia Grant · Acquisitions Associate
“We used to lose time rebuilding the same first-pass model. BrickRatio lets us reject weak listings in under four minutes.”
Daniel Mercer · Mortgage Broker
“The second tool is useful when a borrower wants to know how far a refinance can stretch before cashflow becomes thin.”
Priya Sandford · Private Investor
“The assumptions are visible. That matters more than a glossy dashboard when you are comparing two imperfect deals.”
Frequently asked questions
Answers kept deliberately direct.
Does BrickRatio replace a full valuation model?
No. It is for screening and comparison. A lender-grade or investment committee model still needs debt structure, tax, and scenario layers.
What operating costs should I enter?
Include realistic maintenance, insurance, compliance, management, and any service charge. If you are unsure, start high rather than low.
Can I use it for HMOs or mixed-use assets?
Yes, but specialist assets deserve higher caution around voids, repairs, and management friction.
Why show cap rate and NOI together?
Cap rate without NOI detail invites false comfort. A high ratio can still rest on fragile rent or missing costs.
Can I share results with a colleague?
Yes. Use the copy button and paste the summary into your deal note, team chat, or memo.
Is registration required?
No. The tools are open and accessible without sign-up.
