Commercial real estate portfolio management software is bought to answer questions about the whole rather than the parts, and in practice four numbers carry most of that. Each is computed across every lease in the portfolio, which is why the product has to hold leases as structured data rather than as documents, and why a portfolio product with a weak lease model produces four confident answers that are all slightly wrong.
Weighted average unexpired lease term
The income-weighted average of how long the leases have left, usually measured both to expiry and to the earliest break. It is the single most quoted portfolio figure in commercial property, and the two versions differ sharply where breaks are common. The system must hold break dates as data and be explicit about which basis a figure uses, because quoting one and meaning the other misleads a lender or a buyer.
The expiry profile by year
How much income falls due for renewal in each of the next several years. A profile with a cliff in one year is a refinancing conversation and a leasing plan; a flat profile is neither. This report is what turns lease management from administration into asset management, and it cannot be produced from a document folder.
Concentration, by tenant and by sector
What share of income comes from the largest tenant, and from any one sector. Concentration is the risk that shows up all at once. A portfolio that looks diversified by property count can be concentrated by income, and the two views differ enough that both belong in the reporting rather than one standing in for the other.
The real cost of a vacancy
Not just the lost rent: void rates and other outgoings the landlord picks up, service charge shortfall spread over remaining tenants or borne by the owner, and the cost of re-letting. A product that computes this from the property's own figures makes the renewal-versus-turnover decision arithmetic rather than instinct, and it is the calculation most often done on the back of an envelope.
Questions people ask about commercial real estate portfolio management software
What is a weighted average unexpired lease term?
The income-weighted average remaining lease length, quoted to expiry or to the earliest break. Say which basis you mean; they differ materially.
Why does concentration matter more than property count?
Because income is what services debt. Ten properties with one tenant taking most of the rent is a concentrated portfolio however it looks on a map.
Can accounting software produce these?
No. All four are computed from lease terms, which accounting software does not hold in a structured form.
