There is a version of rental property ownership where your dashboard updates without you logging in. Your PM statement lands in your inbox, gets forwarded automatically, and Knox reads every line item, creates the transactions, and files the document. Your insurance renewal hits your Dropbox folder and Knox extracts the coverage details, updates the policy record, and sets an expiration alert. A receipt photo you snapped at the hardware store turns into a categorized expense in about 10 seconds.
That version is not theoretical. It is exactly what happens when you set up DoorVault’s cloud sync workflow correctly.
This post walks through that workflow step by step. By the end, you will understand how to connect your existing tools, what Knox does with every document type, and what the actual time savings look like once the system is running.
The Problem With Manual Uploads
Most landlords have a fragmented document problem. PM statements live in one email thread. Insurance policies are in a different folder. Lease agreements were somewhere on your desktop from two years ago. Closing documents are still in the escrow company’s portal. Receipts are in a shoebox or a camera roll you keep meaning to organize.
Every time something needs updating, you have to find the document, open your tracking system, manually enter the data, and file the PDF somewhere logical. For a single property, this takes maybe 15 to 20 minutes a month. For a portfolio of 5 to 10 properties with multiple PMs, multiple insurance carriers, and ongoing rehab activity, you are looking at 8 to 12 hours monthly just keeping records current.
That is the wall. And most landlords hit it between properties 3 and 5, right when things start getting serious. The manual approach that barely worked for 2 properties completely breaks down at scale.
The fix is not working harder or faster. It is setting up a system where the documents feed themselves into the right place automatically.
Three Input Channels, One AI Engine
DoorVault gives you three ways to get documents and data into Knox without manual data entry.
Channel 1: The Knox Email Inbox
Every DoorVault account gets a unique Knox email address. You forward any property-related email to that address and Knox handles everything automatically. PM statements, invoices, insurance renewals, tax bills, closing documents, inspection reports, lease agreements. Anything that shows up in your inbox related to a rental property can go to Knox.
Knox extracts the attachments, reads the document content, categorizes everything, files it to the correct property, and creates any relevant transactions. A PM statement that used to take 20 minutes to reconcile manually takes Knox about 30 seconds.
Channel 2: Cloud Storage Sync (Dropbox and Google Drive)
Connect your existing Dropbox or Google Drive account via OAuth and DoorVault monitors your connected folders continuously. Drop a file into a synced folder and Knox picks it up, runs it through the full document intelligence pipeline, and files it. No manual upload. No login required.
Before your first sync, DoorVault shows you a pre-scan: how many files it found, how many are duplicates, how many are photos versus PDFs. You approve, and Knox processes everything in priority order: entity documents first, then property documents (closing disclosures, deeds, mortgages), then supporting documents (leases, insurance, PM statements, tax bills). After processing, documents get reorganized into a clean folder structure by State, Property, and Category.
Going forward, anything new you add to the synced folder gets processed automatically.
Channel 3: Direct Upload and Receipt Scanning
For documents that do not come through email or cloud storage, you can upload directly via the web app or snap a photo of a receipt. Knox extracts vendor, amount, date, and category from a receipt in about 10 seconds and creates the transaction automatically. For larger documents, the same 5-stage pipeline runs: classify, extract, verify, match, apply.
What Knox Does With Each Document Type
Knox Document Intelligence recognizes 72 document types and extracts the relevant structured data from each. Here is what that looks like across a few common document categories:
PM Owner Statements: Knox reads every line item. Rent collected, management fee, repair charges, reserves, disbursement total. It creates transactions for each line, files the PDF to the correct property, and flags anything unusual, like a fee percentage that changed or a charge that does not match prior months.
Insurance Policies and Declarations: Knox extracts carrier, policy number, coverage amounts, premium, and expiration date. The expiration gets added to Document Expiration Tracking, which sends you an alert before renewal. If the premium changed significantly from the prior year, Knox surfaces that through Anomaly Detection.
Closing Disclosures and Settlement Statements: Knox extracts 30 or more fields: purchase price, loan amount, interest rate, closing date, escrow amounts, title fees, and more. A document that takes 45 to 60 minutes to enter manually takes Knox about 30 seconds.
Tax Bills: Knox categorizes the document, extracts the assessment and payment amounts, creates the expense transaction, and files by property and tax year.
Inspection Reports: Knox extracts the inspection date, inspector, findings, and any required repairs. The document gets filed to the correct property and Knox surfaces any compliance items as nudge cards on your dashboard.
Lease Agreements: Knox extracts tenant names, lease start and end dates, rent amount, and deposit terms. Lease expiration gets tracked so Knox can remind you 60 days before renewal.

Setting Up the Automated Email Forward
The Knox Email Inbox becomes even more powerful when you automate the forwarding. Most email clients let you create rules that forward emails matching specific criteria automatically. Here is a practical setup:
Create an email rule that forwards any email from your PM, insurance agent, lender, or local tax authority directly to your Knox inbox address. If you also save PM statement attachments to a shared Dropbox folder as part of your existing workflow, the cloud sync handles those without any forwarding needed.
Once these rules are in place, you genuinely stop logging in to process documents. Knox processes them as they arrive. You check your Knox Activity Log when you want a summary of what changed, not because you have to review every line manually.
This is what makes passive income actually passive. Not just on the property operations side, but on the investor back-office side as well. If you own properties in multiple states and rely on remote PMs, this workflow is the difference between flying blind and having real-time visibility.

What Runs Continuously After Setup
Once your cloud sync and Knox inbox are connected, several things run in the background without any action from you.
Knox Anomaly Detection monitors every transaction as it comes in. Duplicate charges, missing rent, expense spikes, fee changes. If a PM’s management fee percentage quietly increased from 8% to 10%, Knox catches it and flags it. This is the kind of thing that goes unnoticed for months in a manual workflow. Knox surfaces it within hours of the transaction hitting your portfolio.
Document Expiration Tracking runs against every insurance policy, lease, inspection certification, and compliance document in your vault. As expiration dates approach, Knox Nudge Cards appear on your dashboard. No calendar entries required. No reminders to set.
Property Health Scores update as new data flows in. If a property’s expenses are running high relative to income, or if a lease is approaching month-to-month status, Knox reflects that in the health score and surfaces it with context. This is the kind of ongoing monitoring that used to require a monthly review session with a spreadsheet.
Knox Chat stays current with everything. Ask it what your portfolio NOI looks like across all properties, what your total insurance exposure is, or whether a specific property’s cash flow has changed in the last quarter. Knox answers from your actual data, not from a formula you built and forgot to update.

The Real-World Time Math
Here is what the time savings actually look like for a 10-property portfolio, based on the tasks Knox automates:
- PM statement processing: 20 minutes per statement, once a month per property. 10 properties, 10 statements. That is 200 minutes or roughly 3.5 hours a month, down to about 5 minutes of review
- Insurance and lease document entry: 15 to 30 minutes per document. Knox handles it in under a minute
- Receipt entry: 2 to 3 minutes per receipt manually. Knox does it in 10 seconds
- Monthly reconciliation and transaction review: 2 to 4 hours manually. Knox creates transactions automatically and surfaces exceptions only
- Finding a specific document when your lender or CPA asks for it: 10 to 15 minutes of inbox searching. Knox returns it in seconds via Document Vault search
Total monthly time on a 10-property portfolio: from 8 to 12 hours down to 15 to 30 minutes of reviewing what Knox flagged.
That is the system. Not magic. Just consistent automation across every input channel, so you only look at your data when you want to, not because you have to.

Frequently Asked Questions
Does DoorVault only work with Dropbox and Google Drive, or can I use other cloud storage?
Right now, DoorVault’s Cloud Storage Sync connects to Dropbox and Google Drive via OAuth. If you use a different cloud storage provider, you can still get documents into Knox through the Knox Email Inbox (forward any email or use your email client to send attachments) or by uploading directly through the web app. The Knox Email Inbox handles the same document types as the cloud sync, so you get the same automated processing regardless of which input channel you use.
What happens if Knox misreads a document or extracts the wrong data?
Every Knox action goes through the Knox Activity Log before it is applied. You can review pending changes, approve or reject them, and revert any single field or an entire extraction with a full before-and-after snapshot. Knox is also designed to flag its own uncertainty. If a field could not be extracted with confidence, it surfaces that for your review rather than writing in a bad value. Nothing changes in your portfolio without passing through this review layer.
Can I set up email forwarding rules so I never have to manually forward anything?
Yes. Most email clients (Gmail, Outlook, Apple Mail) support automatic forwarding rules based on sender, subject line, or keywords. Once you set up rules to forward emails from your PM, insurance agent, lender, and tax authorities to your Knox inbox, the workflow runs without any manual action on your part. For a combined email forwarding and cloud sync setup, you can also automate your email client to save PM statement attachments directly to your synced Dropbox or Google Drive folder, and Knox will pick them up from there.
Does Knox process every file in my Dropbox or just a specific folder?
You choose which folders to connect. DoorVault does not get access to your entire Dropbox or Google Drive. You grant access to specific folders, and Knox monitors only those. You can point Knox at a folder you already use for property documents, or create a dedicated folder just for DoorVault processing. The pre-scan before the first sync shows you exactly what files are in the connected folder so there are no surprises.
What document types does Knox recognize?
Knox recognizes 72 document categories, including closing disclosures, settlement statements, lease agreements, PM owner statements, insurance policies (hazard, flood, umbrella, liability), tax bills, inspection reports, appraisals, Section 8 vouchers, HAP contracts, deeds, mortgages, promissory notes, loan modifications, payoff statements, HOA documents, entity formation documents, and dozens more. If you upload a document type Knox has not seen before, it flags it for manual categorization rather than guessing incorrectly.
