The problem

Manual work is quietly
eating your margin.

A 2,000-pad portfolio pays $127K–$210K per year in labor for work that requires no expertise — just reading, tracking, and following up. DoorTech AI does all of it.

01Delinquency management
45–60 min / account
200–400 delinquent accounts per month at a 2,000-pad portfolio. Each one means monitoring the rent roll, generating a notice, tracking responses, and managing escalation — done manually, every time.
02Lot rent renewals
2–3 hrs / renewal
State law requires specific timing and language for lot rent increase notices. Getting it wrong has legal consequences. Getting it right manually takes 2–3 hours per renewal across 40–80 renewals per month.
03Maintenance coordination
20–40 min / request
400–800 maintenance requests per month must be categorized, assigned, tracked, and closed. Most coordination still happens by phone and email with no systematic follow-up.
04Resident onboarding
3–5 hrs / move-in
Every move-in requires screening review, lease prep, utility coordination, welcome packet, and a 30-day check-in. Onsite managers juggle this across 8–20 active move-ins per month per community — and details slip through the cracks.
05Compliance notices
45–90 min / notice
Cure notices, eviction prep, and non-renewal notices must meet your state's manufactured-housing law for language, delivery method, and timing. One mistake can invalidate an eviction proceeding.
Annual labor — 2,000 pads
The same work, for 43% less.

Every additional pad widens the gap. Scale headcount by zero — scale margin by 7–8% annually as lot rent compounds.
The agent suite

Five agents.
One platform.

Each agent is purpose-built for MHC workflows, native to Rent Manager and other major PMS platforms, and configurable to your community's escalation rules. They run continuously; managers review only what matters.

A — 01
Delinquency
Monitors rent roll daily. Sends Day 1/5/10/14 notices via SMS and email. Tracks payment plans. Assembles legal-ready documentation at Day 14.
Day 1
every late account, every time
A — 02
Renewal
Identifies expiring leases 90 days out. Pulls market comps. Generates lot rent increase notices formatted to your state's law. Tracks responses, escalates non-responders.
90 days
advance notice, automated
A — 03
Maintenance
Receives requests via SMS or portal. Categorizes, assigns to approved vendor, tracks completion, and closes loop with resident. Flags overdue work orders.
2 min
request to vendor assigned
A — 04
Onboarding
Drives the full move-in sequence from approved application to 30-day check-in: screening, lease prep, move-in checklist, utility reminders — all automated, all logged in Rent Manager.
Zero
manual steps in the move-in process
A — 05
Compliance
Generates legally-compliant notices — lot rent increases, cure notices, non-renewals — formatted per state law with correct timing, delivery method, and language. Manager approval required before sending; every notice logged.
100%
notice compliance, every jurisdiction

Technology

Built for your PMS.
Powered by frontier AI.

DoorTech AI is an integration layer, not a replacement. Your team keeps using Rent Manager (or your current PMS) exactly as they always have — agents run in the background and every action is logged back to the resident file.

Bidirectional PMS integration
Native integration with Rent Manager and other major PMS platforms. Agents pull live data and log every notice, action, and escalation back into each resident's record. Complete audit trail.
Frontier AI reasoning
A state-of-the-art reasoning model parses resident context, generates notice language, and decides when to escalate. AI cost per 2,000-pad portfolio: under $40/month.
Human-in-the-loop by design
Configurable escalation thresholds. Compliance notices require manager approval. Edge cases route to humans with a pre-assembled summary. Every agent knows when to stop.
