Move-Out Money Check — a startup idea for people asking “Can our landlord push us out early and still make us pay rent through the end of our lease?”

A guided checker for California renters leaving a lease early or just after it ends: it walks through rent owed after move-out, the landlord's duty to try to re-rent, and the 21-day security deposit deadline, then builds a dated timeline and a polite demand letter.

The problem people are complaining about

On Nov 1, 2026, a thread titled “Can our landlord push us out early and still make us pay rent through the end of our lease?” was #9 in our daily ranking of Reddit problems. The thread was posted in r/legaladvice. It drew 66 comments and 326 upvotes. Other phrasings of the same question: “[CA] Can our landlord push us out early and still make us pay rent through the end of our lease”. Move-Out Money Check is aimed at that need: a guided checker for California renters leaving a lease early or just after it ends: it walks through rent owed after move-out, the landlord's duty to try to re-rent, and the 21-day security deposit deadline, then builds a dated timeline and a polite demand letter.

Who the customer is

Renters who agreed to leave early, were asked to leave by the landlord, or moved out at lease end and are now being billed rent for months they didn't live there, while the deposit hasn't come back. They are usually dealing with a few thousand dollars and a landlord who knows the rules better than they do. They want to know quickly what the law generally says, what dates matter, and how to ask for the money in writing before deciding whether small claims court is worth it.

In short, the first customer to target is: California tenants who moved out (or are being pushed out) and now face rent charges or a late or missing deposit return. Start with the narrowest version of this group you can reach directly, ideally in the same communities where the problem was posted, rather than trying to serve everyone with the problem at once.

The idea

Move-Out Money Check is an info product idea. A guided checker for California renters leaving a lease early or just after it ends: it walks through rent owed after move-out, the landlord's duty to try to re-rent, and the 21-day security deposit deadline, then builds a dated timeline and a polite demand letter. It makes money through free checker; paid letter pack with a filled-in demand letter, evidence checklist and small claims filing guide.

Pricing guess

Estimate: free checker; $15-29 for the letter and small claims pack. This is our estimate, not market data: treat it as a starting hypothesis and test it with real buyers before relying on it. Price anchors from the alternatives below and what people already spend on workarounds are the best reality check.

MVP you can build

Weekend: a form that asks for lease dates, move-out date, whether the landlord asked them to leave, rent paid and deposit status, then shows a timeline against California's 21-day deposit rule and general rules on rent after an early move-out, with links to the official California courts self-help pages. A template fills in a demand letter the user can download. Keep the first version deliberately small: the goal is to learn whether people use it and pay, not to build every feature.

How to validate it in three steps

1. Share the free checker in renter communities in California cities and count completed checks.
2. Ask ten renters who used it whether the letter pack would have been worth $19 to them.
3. Track how many users say the landlord answered or paid after they sent the letter.

Decide your success threshold before you start each step (for example, a number of signups or pre-orders), so the result actually tells you something.

Competition & existing alternatives

Nolo publishes free tenant articles and books, tenant unions and legal aid groups offer advice, and the California courts self-help site explains small claims, but none of them builds a personal timeline and letter from the user's own dates Before building, try each alternative as a customer would and note exactly where it fails the people in the threads; that gap is your positioning.

Risks

• It must stay general information and send complex disputes to legal aid or an attorney.
• Rules differ by state and some cities add their own, so expanding past California takes careful research.
• Each user needs it once, so growth depends on search traffic and word of mouth.

How we scored it

Opportunity score (6/10) rates how well the idea suits one founder building with AI or no-code tools: demand (30%, from the signal score), pain and willingness to pay (25%), buildable with AI or no-code (25%), easy first customers (10%) and room in the market (10%), each rated 0–10 and combined into a whole number. Signal score (4/10) is calculated from our data only: 2 points for one thread, 4 for two, 6 for three or more; +1 for each extra day the problem appears (max +2); and +2 if it ranked in the daily top 10, +1 for top 25, +0.5 for top 50. Neither score is a forecast. See our scoring methodology and how it works.
