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.

· Where DoorVault fits

The asset platform for investors who use property managers.

Three jobs, three kinds of tool. Stessa and Baselane do bookkeeping for landlords who self manage. Buildium and AppFolio are the software your manager operates. DoorVault is the owner side. It sits above your manager and audits the numbers they send you.

Direct answer

If you own rentals and a property manager runs them, DoorVault is built for you. Knox reads every owner statement, reconciles it against the deposit that hits your bank, and keeps an independent set of books, so you see real NOI, equity, and return across every property and every manager. Stessa and Baselane assume you collect rent yourself. Buildium and AppFolio are the software your manager runs. DoorVault is the only one of the four built for the owner who oversees rather than operates.

DoorVault is read only. It never holds your money. It audits any property manager against any bank.

· Questions investors ask

Software for investors who use property managers, answered.

What is the best software for investors who use property managers?
DoorVault is built specifically for investors who use property managers. Your manager runs the property day to day. DoorVault runs the asset: it reads every owner statement, reconciles it against the deposit that hits your bank, and keeps an independent set of books, so you see real NOI, equity, and return across every property and every manager. Stessa and Baselane assume you collect rent and manage tenants yourself. Buildium and AppFolio are the software your manager operates. DoorVault is the owner side.
How do I audit my property manager's statements?
Forward the owner statement to your Knox Inbox, or sync your manager's portal once. Knox reads every line, books rent, repairs, fees, and reserves, then reconciles the statement total against the deposit that actually reached your bank. When a deposit comes in short, a charge looks duplicated, or a management fee does not match your agreement, Knox flags it with the evidence attached and drafts the question for your manager. Nothing posts until you approve.
What is the best Stessa alternative for an investor with a property manager?
DoorVault. Stessa is solid free bookkeeping for landlords who self manage. The moment a property manager is in the loop, you need a tool that reads the manager's statements, reconciles them to your bank, and watches for fee and payout errors. Knox does that on every plan, including free. If you self manage one or two doors and want simple income and expense tracking, Stessa is hard to beat. If a manager sends you statements, DoorVault is the better fit.
Can I track NOI across multiple property managers in one place?
Yes. DoorVault unifies RentManager, Buildium, and AppFolio owner portals into one ledger, so NOI, cash flow, equity, and return are calculated across your whole book rather than one portal at a time. Every manager reports in a different format. Knox normalizes them so the portfolio number is finally comparable across managers.
Is DoorVault property management software?
No. DoorVault is owner-side asset management. It does not collect rent, screen tenants, or run maintenance, your property manager does that. DoorVault is read only and never holds your money. It sits above your manager and audits the numbers, so your books stay independent of whoever operates the building.
How is DoorVault different from Buildium and AppFolio?
Buildium and AppFolio are built for the property manager who operates the building and holds the trust account. DoorVault is built for the owner who hired that manager. Rather than running operations, DoorVault ingests the statements your manager produces, reconciles them against your bank, and gives you an independent owner-side view of performance and risk across every manager you use.
Does DoorVault hold my money or collect rent?
Never. DoorVault is read only. Your property manager continues to collect rent and hold the operating and reserve accounts. DoorVault connects to read the statements and bank activity, then verifies that what the manager reports matches what actually moved. You stay in control, and nothing posts to your books without your approval.
How much does DoorVault cost?
DoorVault is free for 2 properties with every feature included, then $29 per month for 10 properties, $79 for 50, and $149 for unlimited. Every plan includes Knox document intelligence, PM statement reconciliation, deal underwriting, and the rest. Plans differ only by how many doors you track and how many Knox credits you get. Nothing is gated behind a higher tier.
What if my property manager's deposit is less than the statement says?
Knox reconciles the statement total against the deposit that actually reached your bank and shows you the gap with the line items behind it. The missing money is usually boring: an uncollected late fee, a reserve top-up, a refund that stayed with a vendor, a short Section 8 HAP payment, or a management fee taken on the wrong basis. Knox names the likely cause, attaches the evidence, and drafts the question to send your manager. You see the missing money, not just a mismatch.
How do I know if my property manager is overcharging me on fees?
Knox checks every management fee against your agreement and against the cycle it was earned in, so a lagged or off-percentage fee gets flagged instead of absorbed into a plausible net deposit. The PM Report Card tracks each manager's fee accuracy, payout timeliness, and statement completeness over time, so a pattern is visible rather than buried.
How do I do taxes for rental properties across multiple LLCs?
Each LLC is a first-class entity in DoorVault with its own properties, profit and loss, Schedule E, and EIN. Because Knox books your statements as they arrive, every entity's Schedule E is export-ready in five CPA formats with no re-keying, and you see both the per-entity and the consolidated portfolio view. Mortgage interest, escrow, and depreciation are already split out.
How do I stop manually entering my property manager's statements into a spreadsheet?
Forward the statement to your Knox Inbox, or sync the portal once, and Knox reads every line and books the rent, repairs, fees, and reserves automatically, then files the PDF to the right property. Reconciling a statement by hand runs 30 to 60 minutes; Knox does it in seconds, and every entry links back to the source page so you can check its work.
Can I use DoorVault as an out-of-state or passive investor with a property manager?
Yes, that is exactly who it is built for. DoorVault is owner-side and read only, so it never runs operations or holds your money. It ingests your manager's statements and your bank activity and gives you a trustworthy view of NOI, equity, and risk across every property from anywhere, without you touching the day to day. Your manager keeps operating; you finally get the asset view.
How does DoorVault catch a duplicate or missing charge on my rental?
Every night Knox Night Watch verifies each statement against your bank deposits, hunts duplicate charges, and watches deadlines, then leaves you a morning brief with the evidence attached and the manager question drafted. You wake up to the catch and the decision, not to a spreadsheet you have to rebuild.
