A rent roll can show current income without showing where the next operating decision sits. Most owners and buyers read it as a list of numbers. We read it as a map of what needs attention, what needs money and what drives the price.
A rent roll lists tenants, lease terms, square footage and rent. It adds up to a total, and that total becomes the basis for value, debt sizing and return projections.
What it does not show is the cost of keeping that income. A lease expiring in six months at market rent is not the same as a lease expiring in six months at 20 percent below market with a tenant whose maintenance requests have been deferred. A spreadsheet counts both the same way. Operating the building means seeing the difference.
The rent roll hides three things. Which leases will renew without drama. Which leases will need capital to renew. And which tenants you would not sign again if their lease were up today.
We sort every lease into one of three piles.
Pile one: leases that renew near face rent. Tenants paying at or near market, in good standing, with no serious complaints, in space that is in reasonable condition. Renewal is a conversation about terms, not a rescue.
The question that decides pile one: if this lease expired tomorrow, would we expect to renew it at the current rent or better without significant concessions or capital?
Pile two: leases that need money to renew. Tenants who will stay, but only if something is spent. The HVAC serving their suite is failing. The roof leaks over their space. They have been asking for improvements that were deferred. Or they are paying above market and will ask for a reduction or an improvement allowance to stay.
The question that decides pile two: what will it cost to keep this tenant, and is that cost already in the budget?
Pile three: tenants we would not sign again. Tenants who pay late, damage the property, generate complaints from other tenants or run a business that no longer fits the building. They may be current on rent. They may have years left on the lease. But if the lease were up today, we would not renew it.
The question that decides pile three: what is the cost of keeping this tenant, and what is the cost of replacing the income?
Pile one calls for attention to the lease itself: term, escalations and the conditions that help preserve the rent. Does the lease have annual increases? Does the tenant have expansion or contraction rights that could disrupt the building? Is the renewal option at market, or at a fixed rate that could become a problem? Pile one is not passive income. It is income that stays as long as nobody ignores it.
Pile two requires understanding the cost of renewal before treating the income as secure. Estimate the capital required. Compare it with the cost of re-leasing the space. Decide whether the tenant is worth the investment or whether the space is better re-tenanted. The comparison with a new lease is worth doing properly, because a renewal usually carries a better effective rent than its face rent suggests.
Pile two is also where underwriting separates operators from spreadsheet buyers. An operator knows what it costs to replace a rooftop unit, how long it takes and what happens to the tenant relationship if it fails during the lease. A buyer without operating experience sees a line item and guesses.
Pile three requires a different question. A problem tenant does not just pay rent. They create risk. They can push other tenants out. They take management time that should go to better tenants, and they delay capital work because attention goes to their issues instead of the building.
Pile three is where the price actually gets set. A spreadsheet counts that income the same as pile one, and a buyer who does not operate buildings will underwrite it the same way: current income, renewal assumed. An operator underwrites pile three as income at risk, adds the cost of vacancy and re-leasing, and prices the building accordingly.
That is not pessimism. It is what operating buildings teaches. For an owner, it means pile three is where the most value can be protected, by dealing with it on your own timeline rather than the tenant's. For a buyer, it means pile three is where overpaying happens.
A small office building has six tenants and total annual rent of $300,000.
The rent roll says $300,000. The sort says $145,000 in pile one, $105,000 in pile two and $50,000 in pile three. Pile two needs an estimated $80,000 of capital over the next two years. Pile three needs a decision: keep absorbing the management time and the risk to the other tenants, or plan for the vacancy and around $60,000 of re-leasing cost.
The figures are illustrative, not a specific building or client.
The same $300,000 reads differently after the sort. Pile one is secure if it is managed. Pile two is secure if the money is spent. Pile three is not secure, and a buyer who underwrites it as secure will overpay for it.
Pull your rent roll this week and put every lease in one of the three piles, using the questions above.
For pile one, read the leases. Check renewal options, escalation clauses and any rights that could disrupt your plan. Make sure you are not assuming a renewal that carries a below-market option rate.
For pile two, estimate the capital each renewal needs and compare it with the cost of re-leasing. Decide now whether you will spend to keep the tenant or plan for the turnover.
For pile three, decide whether the tenant is worth keeping. If not, start planning the exit: the vacancy, the re-leasing cost and the build-out. Do not wait for the lease to expire to make the decision.
The sort does not change the rent roll. It changes what you do next. We argue renewals for a living, and this is where every renewal conversation we have starts.
