Tenant Screening That Looks Beyond Debt-to-Income: startup idea with real demand
An applicant earns $65,000 (enough on paper) but has $55,000+ in delinquent debt and a 561 credit score. The '30% of income' rule doesn't capture real risk.

Tenant Screening That Looks Beyond Debt-to-Income is a startup idea for landlords and property managers. An applicant earns $65,000 (enough on paper) but has $55,000+ in delinquent debt and a 561 credit score. The '30% of income' rule doesn't capture real risk. A thread in r/realestateinvesting drew 22 upvotes and 100 comments between Sep 14, 2026 – Oct 14, 2026. People get by with TransUnion SmartMove, RentPrep, and Zillow screening, and that still leaves this job open. Hotness is 3.25, Warm. Real but moderate pain. Clear willingness to pay. The thread drew 22 upvotes and 100 comments. Crowded with decent tools. A few weeks of work. A first version is a moderate amount of work, about 3–4 weeks, priced between $10 and $49 a month and charged as a fee on each transaction. 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
A tenant scoring tool for small landlords combining income, debt load, employment stability and references into one more accurate risk score than DTI or credit alone.
MVP scope
- Give landlords and property managers a way to do this in one sitting: One risk score combining income, debt load, job stability and references for small landlords.
- 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 fee on each transaction, between $10 and $49 a month. The free path must finish the core job once.
- Ship the web app only. Leave TransUnion SmartMove to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use TransUnion SmartMove, RentPrep, Zillow screening. 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?
Moderate. A tight MVP is about 4 weeks (3–4 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 landlords and property managers. Charge a fee on each transaction, 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.
