In this guide, we break down the essentials of multifamily budget forecasting, from understanding key expense categories to leveraging software solutions like Yardi Forecast Manager. With the right approach, you’ll gain clarity on your property’s financial future and position yourself to meet your financial goals, whatever the market may bring.

What is multifamily budget forecasting?

Multifamily budget forecasting is the process of estimating future revenue and expenses to set financial goals and manage revenue expectations.

Let’s say you buy a 4-plex at $800,000 with 8% APR. Your monthly payment is just over $6k. If tenants occupy all 4 units, and a monthly rental rate of $1,500 covers the mortgage, how much should rent be? How will you calculate operating revenues?

Multifamily budget forecasting is the answer. It’s how to estimate a property’s future income against its expenses by examining potential sources of revenue, as well as operating costs to see how they perform over a given period (typically one year). 

A reliable budget forecast enables you to:

• Secure financing 

• Spot trends and patterns in cash flow

• Make data-driven decisions about rent increases and expenses

• Adjust as needed to reach your financial goals

How do you do budget forecasting in multifamily?

Rental income is the largest source of revenue for most properties. Therefore, all budgets are built around rental revenues. 

So what cuts into rental revenue? Expenses, which come in all shapes and sizes.

For example, right now you may earn more in rental income than your monthly payment, but that can all change during tax season. 

A good budget forecast looks at expenses like:

• Maintenance and operational costs, such as utilities, repairs, maintenance, insurance, and property management fees

• Mortgage payments, interest, and other debt-related costs

• Capital expenditures to cover major repairs or improvements such as roof replacements, HVAC upgrades, or renovations

• Property taxes, liability insurance, and other fees or assessments

• Unexpected expenses or market changes, usually about a 5-10% deposit into a contingency fund

Examining these areas is how you plan for long-term success. Say, for example, you own a 50-unit multifamily property. Here’s what your budget might look like:

Rental Income:

• 50 units x $1,200 monthly rent = $720,000 annual gross rental income

• 95% occupancy = $684,000 annual effective gross income

Operating Expenses:

• Property taxes: $80,000

• Insurance: $25,000

• Utilities (water, electricity, etc.): $60,000

• Repairs and maintenance: $45,000

• Property management fees: $48,000 (6% of EGI)

• Total operating expenses: $258,000

Debt Service:

• $5 million mortgage

• 5.5% interest rate

• 25-year amortization

• Annual debt service: $320,000

Capital Expenditures:

• Roof replacement: $75,000 (every 15 years)

• HVAC upgrades: $30,000 (every 10 years)

• Apartment renovations: $100,000 (every 5 years)

• Annual capital expenditures budget: $41,000

OtherIncome:

• Laundry facilities: $12,000

• Parking fees: $18,000

• Total other income: $30,000

Contingency:

• 5% of effective gross income = $34,200

You have a total annual budget of:

• Effective gross income: $684,000

• Total expenses: $653,200

• Net operating income: $30,800

What is the difference between forecasting and budgeting?

While forecasting and budgeting are related, they serve distinct purposes. 

Budgeting is how you plan to spend your money over a specific time period. Budgets outline expected income and expenses to help you manage cash flow and stay within your financial constraints.

Forecasting, on the other hand, is the process of predicting future financial performance based on past trends and current market conditions. A forecast is a projection of what you think will happen, rather than how you plan to approach it.

What to focus on when budgeting

It’s rarely easy to find places to save money. Things cost money, and sometimes it’s expensive, but here are a few places to check for savings in your budget: 

• Sustainable landscaping that typically uses region-specific plants to save on utilities and meet budget targets.

• Energy-efficient appliances that cost less over time 

• Using digital solutions to minimize repairs and downtime

• Preventative maintenance plans to catch issues early, extend equipment life, and prevent costly emergency repairs

What comes first, a budget or a forecast?

Budgets are concrete figures that don’t change month to month (usually). Because they are more stable than future predictions, they are what you determine first. 

Start by creating a budget outlining revenue sources, expenses, debt service, and other financial costs. Once you have your budget in place, use it to forecast how your property’s financials will perform against any shifts you perceive in economic conditions, market trends, and other factors.

It’s looking at your budget that helps you identify potential shortfalls or windfalls.
