Every single vacancy
That's more than our fee on a room rental

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.

Built for accidental landlords

You Didn't Plan to Be a Landlord. We Planned for You.

DoorStopper is built for people who ended up with a rental, not professional property managers.

🏡

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.

🔑

The Reluctant Keeper

You upgraded houses and kept the old one. Every vacant month burns $2,000. You need it filled, not a software subscription to learn.

🏘️

The House-Hacker

ADU, basement unit, or guest house. Your mortgage depends on filling it fast. You need a tenant, not a dashboard.

Example scenario

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.

OUTBOUND AI: Our Secret Weapon

AI Handles Every Lead. You Just Pick Your Tenant.

Trust & Compliance

Licensed. Insured. Built to Protect You.

We take legal compliance and tenant safety as seriously as we take filling your vacancy.

Licensed Brokerage Operations

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.

Errors & Omissions Insurance

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.

Fair Housing Compliance

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.

Tenant Screening Standards

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.

Data Security

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.

Your Control, Always

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.

Common concerns

Questions Landlords Ask Before Getting Started

Our AI leasing agent has multi-layer fair housing guardrails built in. Every outbound message passes through a compliance filter before sending. The AI is instructed to never discuss, ask about, or react to any protected characteristics. We conduct regular bias testing and review flagged conversations. Additionally, you can choose "Copilot Mode" where you review and approve every AI message before it's sent.
We use professional-grade screening: TransUnion credit reports, national criminal background checks, eviction history, and income verification. Our default standards are conservative — 3x rent income and 620+ credit score. You review every screening report and make the final decision on who to accept. We also offer optional rent guarantee partnerships — for an additional monthly fee, your rent is guaranteed even if the tenant defaults.
Yes, tenant placement for compensation requires a real estate license in most states. That's why DoorStopper operates under licensed real estate brokers in every market. Our broker partners provide the legal umbrella, E&O insurance coverage, and compliance oversight. You're working with a licensed, insured operation — not a tech startup operating in a gray area.
Most properties receive qualified leads within the first 7-10 days. If your listing isn't generating leads, we'll re-optimize the pricing, photos, and copy within the first two weeks. If after 60 days we haven't helped you find a tenant, you can request a full refund. We're incentivized to fill your vacancy fast — we don't get paid until you do.
Every listing is individually crafted by our AI to match each platform's style and best practices. Zillow listings look like Zillow listings. Craigslist posts look like authentic Craigslist posts. Each is optimized for the platform's search algorithm and audience. Your listing won't look mass-produced because it isn't.
Your personal contact information is never shared with prospective tenants. All lead communication flows through DoorStopper's AI. Tenants interact with our system, not your personal phone or email, until you choose to meet them for a showing. Your address is visible on listings (as it would be on any rental listing) but your personal details are protected.
The entire process takes 5 minutes: describe your property, upload photos, and tell us what you're looking for in a tenant. After that, you can manage everything via text message. We'll text you updates like "3 new leads today, 1 qualified — want to schedule a showing? Reply YES." You never need to log into a dashboard if you don't want to.
Absolutely. You have full visibility into every conversation in your inbox dashboard. You can switch between Autopilot (AI sends automatically) and Copilot (you review every message before it's sent). Most landlords start with Copilot and switch to Autopilot after they trust the AI — usually after 5-10 conversations.
We offer a self-service tier at $39-79/mo where you get all our AI tools but stay in the driver's seat. You write (or approve) every message, you manage your own leads, you decide when to send applications. Same technology, your level of control.
Real Results

What It Looks Like In Practice

Real Case Study

Phong Nguyen, Phoenix, AZ

Multi-room property
Before DoorStopper
Property sat vacant for 4 months with manual listings. Expected rent: $1,600/mo. No qualified applicants. A traditional leasing agent would have listed it as a single rental and collected $1,600/mo at best.
With DoorStopper
We identified the property could be split into 3 separate units and placed 3 tenants in 21 days at a combined rent of $2,900/mo. That's 81% more revenue than a traditional agent would have generated.
The insight a normal agent would have missed: A traditional leasing agent would have listed the entire property as one unit for $1,600/mo and moved on. DoorStopper analyzed the layout, identified the multi-tenant opportunity, and placed 3 tenants at nearly double the revenue. That's the difference between filling a vacancy and maximizing a property.
