The documents behind a commercial building decide your basis, your tenants' obligations and your lender's covenants. When a refinance or a sale comes, they all have to be found at once. Here is what to keep, how to file it and where SealedFolio fits.
| Document | Why it matters | Keep until |
|---|---|---|
| Deed and closing statement | Sets purchase price and basis | 3+ years after the sale is reported |
| Loan documents | Rate, maturity, covenants, reserves | Loan payoff, then 3+ years |
| Leases, amendments, estoppels | Rent, term, options, obligations | Lease end plus the claim period |
| Insurance policies and tenant COIs | Proof of coverage for lender and claims | Policy end plus the claim period |
| Property tax bills and appeals | Expense and tenant pass-through | 3+ years after filing |
| Repair and improvement receipts | Deductions, basis and depreciation | 3+ years after the sale is reported |
Retention periods here are common practice, not legal advice; your accountant and lender may require longer. Why improvement receipts matter for basis is explained in rental property depreciation.
SealedFolio stores each document in its vault on your own Mac or Windows PC, encrypted per file with XChaCha20-Poly1305 and attached to a property. When a document is scanned, it is read with on-device text recognition (Apple Vision on Mac, Windows OCR on Windows) and classified as a lease, closing document, tax bill, insurance, receipt or appraisal, and the fields it finds wait for you to confirm before they become transactions. Nothing is uploaded to a cloud service.
It is not an enterprise repository: there is no data room, e-signature, version control or shared access for a team, so export files to send them. Rent rolls and income statements come from the same books, and the same records feed a quarterly risk scorecard. More of the commercial setup is in commercial real estate software without the 50-unit minimum and local property management software.
Every lease and receipt, encrypted on your own computer
SealedFolio Pro is $19 a month or $179 a year for up to 3 properties. Portfolio is $39 a month or $297 a year for unlimited properties. Both come with a 30-day money-back guarantee.
See SealedFolio pricingPer property: the deed and closing statement, loan documents, every lease with its amendments and estoppels, insurance policies and tenant certificates of insurance, property tax bills, service contracts, and receipts for repairs and improvements.
Keep acquisition, improvement and depreciation records for as long as you own the property plus at least three years after you report the sale, because they set your basis and recapture. Keep leases for the term plus the period a claim could still be made.
One organized store for every document on every property, filed by property and type, so a lender, buyer or accountant request can be answered quickly. Enterprise platforms add data rooms, e-signature and permissions.
For a small owner's own files, yes: documents are encrypted per file, attached to a property and classified by type when scanned (lease, closing document, tax bill, insurance, receipt or appraisal). It has no data room, e-signature or shared access.
