Real estate portfolio software is usually evaluated on its reports, which is the wrong end. The reports are only as good as four joins underneath them: which entity owns which property, which leases sit on which property, which cash belongs to which lease, and which debt is secured on what. Every portfolio total is computed across those joins, so a product that models any of them loosely produces confident numbers that cannot be defended.
Entity to property, and the many-to-many nobody plans for
One entity can own several properties and one property can be owned across entities, with percentages. A product that treats ownership as a single field on a property forces the awkward cases into a note, and from then on every entity-level figure is partly manual. Ask how a fifty-fifty joint venture on one building is modelled, and watch whether the answer involves a workaround.
Property to lease, including the parts
A building has units, a unit has a lease, and sometimes a lease covers several units or part of one. Car parking, storage and signage are leased separately and belong to the same tenant. If the model cannot hold a lease across two units, occupancy and passing rent will both be wrong in ways that are hard to see.
Lease to cash, so income is traceable
Rent raised, rent received, arrears and any incentive spread over the term. Where the cash side sits in a separate accounting system, this join is the one that breaks, and a portfolio income figure that cannot be traced to bank transactions is an assertion. Ask to trace one month's portfolio income down to the payments.
Asset to debt, and where the covenants live
A facility secured on one asset, or several, with covenants tested on figures the system already holds. Recording the covenant terms beside the debt turns a quarterly panic into a report. Most portfolio products handle debt as a balance and nothing more, which is exactly the level of detail that is no use when a test approaches.
Questions people ask about real estate portfolio software
Is portfolio software different from accounting software?
Yes. Accounting holds the transactions; portfolio software holds the structure they belong to, which is what makes a total explainable.
What is the commonest modelling failure?
Ownership as a single field, which cannot hold joint ventures or an asset held across entities without a workaround.
Can a spreadsheet hold these joins?
It can hold them and cannot enforce them. That is the whole difference, and it shows up when somebody other than the author has to use it.
