How to Migrate from Buildium: Exporting Your Data and Moving Without Losing History

If you have decided — or are seriously considering — leaving Buildium, data migration is the step that either gets handled cleanly or causes months of operational disruption. Most landlords and property managers who stay on platforms longer than they should cite migration complexity as the primary reason. Usually, that complexity is overstated once you actually understand what the process involves.

This guide walks through the complete Buildium migration process: what data you can export, what format it comes in, what you cannot export, how to prepare before you switch, and how to run a parallel transition period so nothing falls through the cracks.

What Data Lives in Buildium

Before you can plan a migration, you need to know what you have. Buildium stores the following categories of data:

Tenant data:

Contact information (name, email, phone, emergency contacts)
Current lease terms (unit, rent amount, start date, end date)
Move-in / move-out dates
Ledger history (payment records, late fees, credits)
Security deposit amounts and transaction history

Property data:

Property and unit records (address, unit details, status)
Owner information
Associated bank accounts and trust accounts

Financial data:

Transaction history (income and expenses by property)
Vendor payment records
1099 information
Owner distribution history
Bank reconciliation records

Maintenance data:

Work order history (open and closed)
Vendor records
Associated invoices and expenses

Documents:

Lease documents (only if stored in Buildium's document repository)
Inspection reports
Other uploaded files

What is NOT stored in Buildium (or not exportable):

Maintenance request photos (must be downloaded manually from work orders)
E-signed lease documents are stored in Buildium but may require individual download
SMS message history (not exportable)
Historical owner statements beyond what is included in financial exports

Step 1: Audit Your Data Before You Export

Before requesting any exports, spend 30 minutes auditing the accuracy of your current data in Buildium:

Verify all unit records are current (vacant units marked vacant, occupied units have correct tenant and lease information)
Confirm that the current rent amounts, lease start/end dates, and deposit amounts are accurate on each lease
Review your open work orders — are they accurate and up to date, or are there stale tickets that should be closed before migration?
Confirm your vendor list is current and de-duplicated
Verify your chart of accounts organization — this affects how your financial history maps to the new platform

A clean export starts with clean data. If your Buildium records have inconsistencies, you want to fix them before exporting, not discover them after.

Step 2: Export Your Data from Buildium

Buildium's export functionality is accessible from within the platform. Here is what you can export and how:

Tenant and lease data

Navigate to Reports > Rental > Tenant Roster for a CSV export of all current tenant information including contact details and lease terms.

For lease history, the Tenant Ledger report provides per-tenant payment and transaction history. Export these for all active tenants and any tenants with open balances or recent activity (we recommend exporting at minimum the last 24 months of ledger history).

Financial data

The primary financial exports are:

General Ledger — full transaction history by property and account
Bank Registers — per-account transaction history
Income Statement — income and expense summary by period and property

Export these at a minimum for the current and prior two fiscal years. Your CPA or accountant may want additional history depending on open audits or tax situations.

Vendor data

Export your vendor list from Settings > Vendors as a CSV. This becomes your vendor import file for your new platform.

Maintenance records

Buildium does not offer a bulk export of work order history as a single CSV with all detail fields. You can export a work order list with basic fields (date, property, status, category, description), but detailed notes and photos require manual download. Focus your maintenance export on the current open work orders — historical closed orders are archival records that you can retain in Buildium's read-only access after you migrate, rather than trying to migrate every ticket.

Owner and property information

Export your property and unit list from Reports > Property Roster and your owner contact list from Reports > Owner Roster.

Step 3: Download Your Lease Documents

Lease documents and inspection reports stored in Buildium's document repository are not included in data exports. You need to download them manually.

For each active tenant:

Open their tenant profile in Buildium
Navigate to the Documents tab
Download the signed lease and any addenda
Store them in an organized folder structure (organized by property, then unit, then tenant)

This folder structure becomes your document library import for your new platform.

Budget approximately 15–30 minutes to complete this step depending on your portfolio size — it is tedious but important. These documents are your legal records.

Step 4: Choose Your New Platform and Prepare the Import

Before export, confirm that your new platform can accept the following Buildium export formats:

Tenant roster CSV
Ledger history CSV
Vendor list CSV
Property/unit list CSV

Most modern platforms support these standard CSV formats, either natively or through a guided import process. Confirm this before committing to a new platform.

If your new platform offers a migration assistance service, use it. Most AI-native platforms have either self-serve importers or guided onboarding that walks you through mapping Buildium's fields to the new system's data model.

Step 5: Set a Switchover Date and Run Parallel

The cleanest migration approach is a parallel run: you keep Buildium active for one full rent cycle while your new platform is set up and your tenants are onboarded to the new portal.

Week 1-2: Set up the new platform

Import property and unit records
Import tenant data and configure lease records
Import vendor list
Set up your bank accounts and payment processing
Configure your automation workflows (rent follow-up schedule, maintenance routing, communication templates)

Week 3: Tenant portal migration

Send tenants a communication explaining the portal change, effective date, and any new payment instructions
Include login instructions for the new portal
Allow 1-2 weeks for tenants to register before the old portal goes inactive

Rent cycle close: Go live

Process one full rent cycle entirely in the new platform
Confirm that all payments posted correctly
Confirm maintenance routing is working
Generate your first owner report

Final step: Archive Buildium

Request read-only access (rather than full cancellation) for 90 days
This gives you a historical reference window while you verify that all data migrated correctly
Cancel after your financial records are confirmed clean

What You Cannot Easily Recover After Migration

Be especially careful about:

Unpaid balances. Confirm every tenant's balance is accurately reflected in the new platform before going live. An error here results in incorrect statements, disputes, and confusion.
Security deposit balances. These need to match exactly — to the dollar — between Buildium and your new platform. Reconcile these before migration.
Partial-month rent prorations. If you migrate mid-month, confirm how the new platform handles the current cycle's partial billing.

FAQ

How long does a Buildium migration take?

For a well-prepared migration of a 20-50 unit portfolio, expect 1-2 weeks for setup and a 2-4 week parallel run, for a total transition of 3-6 weeks. Larger portfolios take longer. Disorganized data extends the timeline significantly.

Will I lose my Buildium data when I cancel?

Buildium retains your data for a period after cancellation, but the specific window varies. Request your data exports before canceling, and consider keeping a read-only subscription for 90 days after migration to ensure you have a clean reference window.

Can I import historical transaction data into a new platform?

Most platforms can import current tenant records and ledger balances, but importing full historical transaction histories (going back 3+ years) at line-item level is often complex. A practical approach: import your current balances and active tenant records, and retain Buildium access in read-only mode for historical reference.

Should I migrate at the beginning or end of a month?

Beginning of a month is generally cleaner — you start fresh in the new system with a full rent cycle rather than inheriting mid-cycle complexity. If that timing is not possible, reconcile your end-of-month balances carefully before the transition.

Is there an easier way to move from Buildium?

Yes — most modern platforms offer an assisted migration process. See Switching Property Management Software: A Migration Guide for the full process, and The Best Buildium Alternative for platform recommendations.
