Double-entry software for multiple rentals, what actually holds up past the first property
The moment a second property hits the books, the software choice that felt fine for one unit starts showing cracks, specifically around how it handles property-level P&L without forcing a workaround. Say you have five doors across two LLCs. You need to know whether unit 3 in LLC A is cash-flowing, not just whether LLC A is cash-flowing. That split is where most landlord-marketed software fails, because it tracks income and expenses but collapses them at the entity level rather than the property level.
QuickBooks Online handles this with class tracking, one class per property, and if your chart of accounts is set up correctly you can pull a P&L by class and see each door on its own line. The limitation is that class tracking is a workaround, not a native property accounting feature, so discipline in data entry matters more than the software itself. One miscoded transaction and the property-level report is wrong in a way that is hard to spot without a reconciliation specifically by class.
Stessa is built for rental property and gives you property-level reporting natively, but it is single-entry, which means you are not producing a true balance sheet and your accountant will likely recast the data at year end anyway. For an investor who wants to hand clean financials to a CPA without a cleanup bill, that is a real cost to weigh even if Stessa is cheaper month to month.
Buildium and AppFolio are property management software with accounting built in, and they produce double-entry books with property-level reporting as a core function rather than a bolt-on. The price reflects that. If you are self-managing five or more units and want the lease, the rent ledger, and the P&L in one place, the per-unit fee starts to make sense. If you are using a property manager and just need to reconcile their disbursement statements, it is likely more than you need.
The line that matters most in this choice is whether you are also tracking liabilities, meaning mortgages, security deposit obligations, deferred maintenance reserves. Software that does not handle the liability side of the balance sheet is not doing double-entry bookkeeping regardless of what the marketing says. What does your current setup do with the mortgage principal portion of each payment?
