Commercial Rent Benchmarks for Small-Business Negotiations is a startup idea for small-business owners and retailers. A salon owner put $30k into renovating a rented space, then got a renewal offer with a 70% increase for five years, with no data on whether that's market. A thread in r/smallbusiness drew 72 upvotes and 55 comments between Sep 14, 2026 – Oct 14, 2026. People get by with CoStar, LoopNet, and Brokers, and that still leaves this job open. Hotness is 3.35, Warm. Strong pain. Clear willingness to pay. The thread drew 72 upvotes and 55 comments. Gaps in existing tools. Needs integrations or data deals. A first version is a hard build, about 5+ weeks, priced between $10 and $49 a month and charged as a free tier and a paid upgrade. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

A way through
An aggregator of commercial rent data by area and space type for small businesses, helping owners negotiate with data.
MVP scope
- Give small-business owners and retailers a way to do this in one sitting: A 'Zillow for small commercial leases' so owners negotiate renewals with data, not guesses.
- Persist the result and show it again after a reload.
- State the empty case when there is nothing to show yet, with one next step.
- Charge later with a free tier and a paid upgrade, between $10 and $49 a month. The free path must finish the core job once.
- Ship the web app only. Leave CoStar to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use CoStar, LoopNet, Brokers. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Hard. A tight MVP is about 6 weeks (5+ weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is small-business owners and retailers. Charge a free tier and a paid upgrade, and test a price between $10 and $49 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
