Cap Rate, Cash Flow & House Hacks: A Utah Agent Guide
March 7, 2026 · Jocelyn Kaufman
If you want to serve real estate investors in Utah, you need to understand three numbers: cap rate, cash flow, and house hack economics. These are the metrics that drive investor decisions. If you can't calculate and explain them, your investor clients will go somewhere else.
The good news: the math is not complicated. It's straightforward. And once you understand it, you become immediately more valuable to investor clients. You become the agent who speaks their language.
Cap Rate: The Essential Metric
Cap rate stands for "capitalization rate." It's the most common metric investors use to compare properties. Here's the formula:
Cap Rate = NOI / Purchase Price
NOI is "Net Operating Income." It's the property's annual rental income minus all operating expenses (property tax, insurance, maintenance, vacancy, property management). It does NOT include the mortgage payment.
Let's work through a Utah example:
Example: Duplex in Ogden, Utah
- Purchase price: $425,000
- Unit A rental income: $1,600/month = $19,200/year
- Unit B rental income: $1,600/month = $19,200/year
- Total rental income: $38,400/year
Now, subtract operating expenses:
- Property tax: $4,200/year
- Insurance: $1,200/year
- Maintenance (estimate 5% of rent): $1,920/year
- Property management (10% of rent): $3,840/year
- Vacancy (5% of rent): $1,920/year
- Total operating expenses: $13,080/year
NOI = $38,400 - $13,080 = $25,320/year
Cap Rate = $25,320 / $425,000 = 5.96%, roughly 6%
A 6% cap rate in Ogden is solid. It means the property generates 6% annual return (before mortgage) on the investment. Investors use this to compare properties: "Would I rather own this 6% property or a 5% property or a 7% property?" Higher cap rates are more attractive, assuming the neighborhoods and properties are comparable.
That's it. Cap rate is simple once you break it down.
Cash Flow: The Money Left After Mortgage
Cap rate is great, but it doesn't tell the whole story. Cash flow is what actually hits the investor's bank account every month. Here's the formula:
Cash Flow = NOI - Mortgage Payment
Using the same Ogden duplex:
NOI (annual): $25,320
Now assume the investor puts 25% down ($106,250) and finances $318,750:
- Loan amount: $318,750
- Interest rate: 6%
- Loan term: 30 years
- Monthly mortgage payment: ~$1,912
- Annual mortgage payment: $22,944
Annual cash flow = $25,320 - $22,944 = $2,376/year
Monthly cash flow = $2,376 / 12 = $198/month
This duplex cash flows $198/month. That's not huge, but it's positive. Every month, the investor makes $198 after all expenses and the mortgage. More importantly, tenants are paying down the mortgage while the investor makes $198 on top.
This is why investors care about cash flow. Cap rate tells you the property's intrinsic return. Cash flow tells you what you actually make after borrowing costs.
House Hacks: The Shortcut to Cash Flow
A house hack is when an investor buys a multi-unit property (duplex, triplex, fourplex), lives in one unit, and rents out the others. The rental income covers the mortgage and expenses. The investor gets to live for free (or nearly free) while building equity.
House hack example using the same Ogden duplex:
- Purchase price: $425,000
- Down payment: $106,250 (25%)
- Mortgage: $318,750 at 6% for 30 years = $1,912/month
- Investor lives in Unit A (no rent collected)
- Unit B rents for $1,600/month
Operating expenses for both units:
- Property tax: $4,200/year = $350/month
- Insurance: $1,200/year = $100/month
- Maintenance: $1,920/year = $160/month
- Vacancy (on Unit B): $80/month
- Total monthly expenses: $690
Monthly cash flow = $1,600 (Unit B rent) - $1,912 (mortgage) - $690 (expenses) = -$1,002/month
Wait, that's negative. The house hack doesn't work in this scenario. But let's adjust the rent assumption. In a strong market or with a smaller down payment:
- Investor puts 20% down ($85,000) instead of 25%
- Mortgage: $340,000 at 6% for 30 years = $2,039/month
- Unit B rents for $1,800/month (slightly higher estimate)
- Monthly expenses (same): $690
Monthly cash flow = $1,800 - $2,039 - $690 = -$929/month
Still negative. The math shows why house hacks are hard in higher-cost Utah markets (Salt Lake City, Lehi). But move to Ogden or smaller markets, or buy a fourplex instead of a duplex:
Fourplex example in Ogden: $380,000 purchase price
- Investor lives in Unit A (no rent)
- Units B, C, D: $1,400 each = $4,200/month rent
- Mortgage (20% down, 30 years, 6%): $1,824/month
- Operating expenses (estimated 30% of rent): $1,260/month
Monthly cash flow = $4,200 - $1,824 - $1,260 = $1,116/month
This fourplex cash flows over $1,100/month. The investor lives for free and makes cash flow. This is why house hacks in Utah's secondary markets (Ogden, Layton, Farmington, Orem) are popular.
How to Walk Investors Through the Math
When you show an investor a property, walk them through cap rate and cash flow step-by-step. Use actual numbers:
"Here's what this property shows:"
- "Annual rental income: $38,400. Operating expenses: $13,080. That leaves NOI of $25,320."
- "Cap rate: 6%, which is solid for Ogden. You're getting a 6% return on the purchase price."
- "If you put 25% down and finance the rest, your mortgage is about $1,912/month. After operating expenses and mortgage, you cash flow $198/month."
- "It's not a cash flow home run, but you're building equity while making a positive return. Tenants are paying down your mortgage while you collect $198 monthly."
This language signals that you understand investor math. You're not pitching the "great neighborhood" or "updated kitchen." You're analyzing returns. See what Brick & Yield offers for tools that automate this analysis on every property, so you can show investors real numbers instantly.
Why Understanding This Matters for Your Business
Knowing how to calculate and explain cap rate, cash flow, and house hack economics does three things:
- Builds credibility. You speak investor language. You're not another generic realtor.
- Speeds up deal analysis. You can quickly evaluate whether a property makes sense for a client's goals instead of saying, "I don't know, ask your accountant."
- Attracts investor clients. Once you're known as the agent who does investor analysis, investors in your market find you. One client refers another.
In Utah, where the investor market is growing fast, knowing this math separates you from 90% of agents.
Tools to Make This Easier

The future of real estate investing in Utah is data-driven. Agents who provide the data win.
Start With This
Pick one property you know well. Walk through the cap rate and cash flow math manually. Then walk an investor client through it. Notice how the conversation changes. They take you seriously. They trust you. They ask for more deals.
