Between the end of CAM season in mid-May and budget kickoff in early August, CRE finance teams get about ten weeks with no forced deadline, and most of that time disappears into ad hoc work. The best moment to protect next year’s window is now, while this budget cycle is fresh.
Updated October 31, 2026, with Deloitte’s 2027 Commercial Real Estate Outlook, current insurance pricing and a plan for protecting next year’s window. First published May 13, 2026.
The CRE finance year has a fairly fixed shape for calendar-year operators. Prior-year closeout and CAM reconciliations take the first quarter, with statements going to tenants 90 to 120 days after year end. The Q1 reforecast lands in April or May. Budget work starts in August, runs through September and October, and ends with approvals and tenant estimate letters in November.
| When | What’s due |
|---|---|
| January to April | Prior-year closeout, CAM reconciliations, tenant statements |
| April to mid-May | Q1 reforecast against the approved budget |
| Mid-May to early August | Nothing required: the open window |
| August to October | Budget build: assumptions, property budgets, reviews |
| November | Approvals and next year’s tenant estimate letters |
That leaves roughly ten weeks, from mid-May to early August, when nothing has to go out the door. Our CRE budget calendar lays out the whole year month by month, with sources.
Because nothing is due, everything else moves in: asset manager requests, mid-year board materials, leasing committee prep, audit follow-up, the last CAM disputes, and summer time off. Each item is reasonable on its own. Together they use up the one stretch of the year when a finance team could do work that makes the next budget easier.
Teams that start August calm usually don’t have less work in May. They decided ahead of time what the window was for, and put it on the calendar.
Every budget cycle stalls on the same inputs: market rent comps, operating expense benchmarks, utility escalators, insurance, real estate tax projections and capital costs. In August each of those becomes a bottleneck. In June they’re a few calls and emails. Collect them early, note the source and date for each one, and the August kickoff starts from a shared, dated set instead of everyone’s own spreadsheet. Our article on the five assumptions a budget needs covers which ones matter most.
The best record of what broke during budget season is the team’s memory of it, and that fades fast. Note where property managers got stuck, which templates collected the wrong inputs, and which questions asset managers had to ask more than once. Then fix the templates and instructions before the next cycle starts.
The Q1 reforecast produces a line-by-line list of variances by property. Most teams file it once the reforecast is approved. Read it again with next year in mind: each persistent variance, whether an expense that keeps running hot or leasing that keeps lagging plan, is a hint about which assumptions need to change.
The capital plan approved last fall rests on cost and timing assumptions that have already moved. Revisiting it in June is cheap. Discovering in October, after budgets have gone to ownership, that a project now costs more or slipped a year is not.
Deloitte’s 2027 Commercial Real Estate Outlook, based on a survey of 950 executives at owners and investors in North America, Europe and Asia-Pacific, found sentiment cooling: its index fell to 57.8 from 64.9 a year earlier. Respondents expect slower rent growth and vacancies to stay high, and more than 90% plan to increase data and technology spending next year, up from 76%.
Insurance shows why a dated, sourced assumption beats a habit. For several years the safe budget move was to assume insurance would rise sharply. In 2026 the large commercial property market turned: WTW reports rates for large commercial property accounts down 14.5% in the second quarter, after an 8.4% decline a year earlier. Your properties’ renewals may not follow the large-account market, and that’s the point. A team that budgets insurance at last year plus a trend can be wrong in either direction. A team that checked with its broker in June knows which way it is moving.
November and December are the best time to set up next spring, because the 2027 budget is still fresh.
Much of this work is easier when the budget lives in one system rather than a folder of spreadsheets. In Kardin, the roll-forward carries last year’s adjustments, caps and exclusions into the new budget, so the assumption work starts from what was decided last time. Leasing assumption templates keep market leasing inputs consistent across properties, process checklists turn the retro into steps for next cycle, and you can compare budget input to historical data while you build.

For calendar-year operators, roughly mid-May to early August. CAM reconciliations and the Q1 reforecast are done, and budget season usually starts in August.
Build a dated assumptions library, run a retro on the last cycle, review Q1 variances for signals about next year, and check the capital plan against current costs and timing.
Start in late spring or early summer. Rent comps, expense benchmarks, insurance and tax projections are much easier to collect in June than in the middle of budget season.
Not automatically. WTW reports large commercial property rates fell 14.5% in the second quarter of 2026. Check current quotes with your broker rather than applying last year’s trend.
