The Empty Nester
Your kids moved out. The spare room sits empty. You don't want to become a landlord. You just want the income without the headache.
DoorStopper's AI lists your rental on 10+ platforms, actively hunts for matching tenants across local housing channels, qualifies leads 24/7, screens applicants, and handles the lease. Licensed, insured, and legally compliant in every market we operate.

12 million individual landlords in the US face this every time a tenant leaves. Most lose $1,000-2,000 per vacancy to slow leasing.
DoorStopper is built for people who ended up with a rental, not professional property managers.
Your kids moved out. The spare room sits empty. You don't want to become a landlord. You just want the income without the headache.
You upgraded houses and kept the old one. Every vacant month burns $2,000. You need it filled, not a software subscription to learn.
ADU, basement unit, or guest house. Your mortgage depends on filling it fast. You need a tenant, not a dashboard.
Maria in Mesa, AZ had her daughter's old room vacant for 3 weeks doing it herself. Drowning in Facebook Marketplace messages. With DoorStopper, her next tenant was signed in 11 days.
Illustrative example based on market averages. Individual results vary.
Address, photos, preferences, and your ideal tenant, described in your own words. Our AI handles the rest.
AI writes platform-optimized listings and posts to Zillow, Facebook Marketplace, Craigslist, Apartments.com, Zumper, HotPads, Trulia, and more.
While your listing attracts inbound leads, our AI monitors local Facebook groups, Reddit threads, and Craigslist housing-wanted posts for people actively searching for exactly what you're offering. We reach out to them before they even see your listing.
Our AI leasing agent responds to every inquiry in under 60 seconds, 24/7. It qualifies applicants on income, rental history, and your criteria. It schedules showings, runs background and credit checks, generates your lease, and handles e-signatures.
Ready? It starts with describing your place.
Get startedZillow gets 34 million visitors a month. We make sure your property is there, optimized, and getting qualified inquiries, all without you ever logging in.
AI writes your listing, orders photos for maximum click-through, and applies keyword optimization specific to how Zillow ranks search results.
Our AI responds to every Zillow inquiry in under 60 seconds, 24/7. It qualifies income, checks rental history against your criteria, and books tours.
Describe your property once. We publish to Zillow and 9 other platforms, handle all incoming leads from every source, and remove your listing the moment a tenant signs.
We work with Zillow as a licensed syndication partner, not against them. Renters interact with Zillow as they normally would. We manage everything on the landlord side.
Most landlords lose leads because they can't respond at 11pm. Our AI never sleeps.

We take legal compliance and tenant safety as seriously as we take filling your vacancy.
All placements are conducted under a licensed real estate broker. DoorStopper operates as the technology layer under licensed broker supervision, ensuring every transaction is legally compliant. We work through established partners like Prestige Realty Inc., British Realty, LPT Realty, and Realtracs, Inc. We're not a gray-area tech platform. We're a legally-regulated operation.
Every placement is covered by Errors & Omissions insurance. If something goes wrong, and we work hard to make sure it doesn't, you're protected. Our insurance covers the entire placement process from listing to lease.
Our AI is built with multi-layer fair housing guardrails. Every outbound message passes through a compliance filter before sending. We conduct regular paired testing to detect and eliminate bias. We never ask about or react to any protected characteristic.
We use TransUnion-powered background checks, credit reports, eviction history, and income verification. Default qualification: 3x rent income, 620+ credit score, no eviction history. You set the criteria. We enforce them consistently.
Your property data, tenant information, and financial details are encrypted in transit and at rest. We use Supabase with row-level security. Payment processing is handled by Stripe. We never store your credit card numbers.
You retain full decision-making authority. You approve pricing. You choose your tenant. You sign the lease. Our AI recommends and executes, but you decide. We're your agent, not your replacement.
DoorStopper is licensed through established brokerage partners, giving you the same legal protections as a traditional real estate transaction combined with modern AI efficiency.
Same fee as the agent, but 14 days faster. That's $924 in rent the agent model would have lost.
