· Why DoorVault

Property management and asset management are two different things.

Your PM runs the property day to day. DoorVault runs the asset: the money, the returns, and the decisions, across every property and every PM.

Property management

Running the property

Leasing, rent collection, maintenance, tenants, and turnovers. The day-to-day operation of the building.

Your PM · Buildium, RentManager, AppFolio
Asset management

Running the asset

NOI, equity, return, debt, taxes, and what to buy, hold, or sell. The financial performance of your capital.

· Questions investors ask

A few questions before you start.

What is DoorVault?
DoorVault is real estate asset management software for investors who use property managers. Knox unifies owner statements, bank activity, documents, and financial performance across your properties and managers. It also supports deal analysis, loans, entities, and Schedule E exports.
How do I audit my property manager's statements?
Start with the free statement audit, with no account required. In your DoorVault portfolio, upload or forward owner statements and connect your bank activity. Knox checks statement lines, fees, and deposits, and flags differences with the evidence. Proposed money corrections require your confirmation.
Can I track multiple property managers in one place?
Yes. DoorVault brings RentManager, Buildium, and AppFolio owner portal data into one portfolio. You can also upload or forward statements. Track net operating income (NOI), cash flow, equity, loans, and documents across managers and entities.
Does DoorVault replace my property manager?
No. Your property manager handles leasing, maintenance, rent collection, and tenants. DoorVault gives you an independent view of the financial performance of your investments and checks the numbers your managers report.
Does DoorVault hold or move my money?
No. DoorVault reads connected bank activity to reconcile your records. It never holds your money or moves funds. Knox can propose corrections to your portfolio records, but money corrections require your confirmation.
How much does DoorVault cost?
Two properties are free forever. Above that, per door pricing starts at $6 a month. Monthly plans are $29 for 10 doors, $79 for 50 doors with $2 per additional door, and $149 for unlimited doors. Every plan includes every feature. Every account starts with 30 days free, with no card required.
What happens to the statement I upload to the free audit?
No account is required. Knox sends relevant document content to AI service providers to perform the audit. Uploaded files are eligible for cleanup after 30 days. Audit results and contact details follow the Privacy Policy. The audit does not move money or change your bank account.
What if the bank deposit is less than the statement payout?
Knox shows the difference between the expected payout and the deposit, with supporting evidence. It checks possible explanations, such as reserves or timing, and can draft a question for your manager. A flagged difference needs review; it is not proof that money was lost.
Can I prepare rental tax records for multiple LLCs?
Yes. DoorVault organizes properties and records by entity, with per entity profit and loss and Schedule E exports in five CPA formats. Your accountant can review the records and use the exports to prepare your return.
