Every November, we sit down with trailing 12-month financials for every building in our portfolio and build the operating budget for the next year. It takes about two weeks of focused work across our portfolio. It isn't glamorous. It isn't exciting. And it's the single most important thing we do as asset managers.

A budget isn't a wish list. It's a decision document. It tells you what you expect to earn, what you expect to spend, where you expect to invest capital, and what the owner should expect to receive. When the budget is right, there are no surprises. When it's wrong, every month feels like a fire drill.

Here's exactly how we build ours.

Step 1: Pull the Trailing Data

Everything starts with history. We pull the trailing 12-month operating statement for every building. Not the annualized version. The actual month-by-month breakdown.

Why month by month? Because averages lie.

A building might show $4,200/month in repairs on an annualized basis. But when you look at the monthly breakdown, you see eight months at $2,500 and four months at $8,500 during turnover season. That pattern matters. If you budget $4,200/month flat, you will be over budget four months of the year and wondering what went wrong.

We also pull:

Rent roll with lease expirations. How many leases renew in Q1 vs. Q3? When can we push rents?

Vacancy history. Not just the average, but when vacancies occurred and how long units sat.

Capital expenditure log. What did we spend on major improvements and what's still on the list?

Delinquency report. How much rent went uncollected? What's the trend?

This data collection takes two to three days. It's tedious. It's essential.

Step 2: Revenue Projections

Revenue is where most budgets go wrong, usually on the optimistic side. Here's how we stay honest.

Current rents vs. market. We comp every unit type against the current market. If our two-bedrooms are at $825 and the market supports $875, we know we have $50/unit/month in upside. But we don't budget 100% of that upside. We assume we capture 70-80% of the gap over the budget year because not every lease expires in January and not every tenant accepts a full increase.

Lease expiration schedule. If 40% of leases expire in the first half of the year, we can push rents faster. If most leases expire in Q4, revenue growth is back-loaded. The timing matters for cash flow projections.

Vacancy assumption. We budget 5-7% vacancy for B-class product in the Omaha metro. This accounts for turnover time between tenants, which typically runs 14-21 days in our operation. We don't budget 0% vacancy even if the building is currently full. Full buildings don't stay full forever.

Loss to lease. This is the gap between what you're charging and what you could charge on existing leases that haven't yet renewed. We track this monthly because it tells us how much revenue is sitting on the table waiting for lease expirations.

Other income. Pet fees, late fees, application fees, laundry income. We budget these conservatively based on trailing actuals, not optimistic projections. Late fees in particular aren't something you want to grow. If your late fee income is going up, your collection process has a problem.

Step 3: Expense Budgeting

This is where the real work happens. Every expense category gets reviewed individually against trailing data, vendor contracts, and market conditions.

Fixed Expenses

Property taxes. We check the current assessed value and apply the known mill levy. If a reassessment is coming (which happens after acquisition or major improvement), we budget for the increase. In Douglas County, we have seen post-acquisition reassessments bump taxes by 15-25%. If you aren't budgeting for that, your NOI is going to take a hit.

Insurance. We get renewal quotes in October, before the budget is finalized. Insurance in the Midwest has been climbing 8-12% annually over the past three years. We don't assume last year's premium. We budget the actual renewal number.

Management fees. This is our fee, typically 8-10% of collected revenue depending on the asset. It scales with revenue, so it's a variable fixed cost. We budget it as a percentage of our projected collections.

Variable Expenses

Repairs and maintenance. This is the line item that swings the most. We look at trailing data, age of systems, and the capital plan to estimate routine repairs. For a well-maintained B-class building, we budget $500-$700 per unit per year for routine maintenance. Older buildings with deferred maintenance run higher, sometimes $900-$1,200 per unit.

Turnover costs. We estimate turnover based on historical rates and lease expirations. Our average turnover cost is $1,800-$2,500 per unit including cleaning, paint, minor repairs, and vacancy loss. If we expect 20% turnover on a 20-unit building, that's four turns at roughly $2,000 each = $8,000 budgeted for turnover.

Utilities. Owner-paid utilities (common area electric, water/sewer, trash) get budgeted based on trailing data with a 3-5% inflation adjustment. We review utility bills for anomalies. A sudden spike in water usage usually means a running toilet or a leak that's costing the owner money every month.

Landscaping and snow removal. Contract-based, so we know the number. If we're rebidding the contract, we get quotes before budget season. In Omaha, snow removal isn't optional. We budget based on a normal winter, with a contingency line for heavy snowfall.

Pest control. Contracted quarterly at a fixed rate. One of the most predictable line items we have because we moved to a preventive model.

Step 4: Capital Planning

The capital budget is separate from the operating budget, but they inform each other. Capital improvements affect future revenue (through rent increases) and future expenses (through reduced maintenance).

We maintain a 5-year capital plan for every building. Each year, we pull the next 12 months of planned improvements and build them into the budget.

Examples from a current budget cycle:

Roof replacement on a 12-unit building: $38,000. Funded from reserves and owner contribution.

Unit interior upgrades (4 units): $6,500/unit for new flooring, fixtures, and appliances. Enables a rent increase of $75-$100/unit/month.

Parking lot seal and stripe: $4,200. Deferred from last year.

Common area lighting upgrade to LED: $1,800. Pays for itself in utility savings within 18 months.

Capital improvements are prioritized by ROI. The unit upgrades that enable rent increases go first. The cosmetic improvements that improve curb appeal but don't directly generate revenue go last.

Step 5: Owner Review and Approval

The final budget goes to the property owner in a format that shows:

Projected NOI vs. prior year actual

Revenue growth assumptions with supporting market data

Expense changes with explanations for any line item that moves more than 10%

Capital plan with costs, timeline, and expected return

Cash flow projection showing monthly distributions

We walk through the budget line by line. No surprises. If we're projecting lower distributions because of a capital project, the owner knows why and agrees to the reinvestment before we spend the money.

This is where trust gets built. An owner who understands the budget and agrees to the plan doesn't call in April asking why their distribution was $400 less than expected. They already know. They approved it.

The Accountability Loop

A budget without accountability is a spreadsheet that sits in a folder. Every month, we run a budget-vs-actual report and review variances. Any line item that's off by more than 10% or $500 gets investigated and explained.

Sometimes the variance is fine. Insurance came in lower than budgeted because we found a better carrier mid-year. Great. Sometimes it isn't fine. Repairs are running 30% over budget because a plumbing issue we didn't anticipate. That gets flagged, the owner gets notified, and we adjust the forecast.

The goal isn't to hit the budget perfectly. The goal is to never be surprised. Surprises in property management mean someone wasn't paying attention. The budget is your early warning system.

This process isn't complicated. It's just disciplined. And in a business where most property managers hand owners a year-end statement and hope for the best, discipline is a competitive advantage.
