Looking at an apartment building in North Park and wondering what a cap rate really tells you? If you invest or own locally, you know the numbers matter, but context matters more. In this guide, you will learn what a cap rate is, how to calculate it, what drives it in North Park, and a simple process to estimate a realistic range before you write an offer or price a sale. Let’s dive in.
Cap rate basics
A capitalization rate, or cap rate, is a quick way to gauge an apartment building’s current, unlevered return. You calculate it by dividing annual Net Operating Income by the purchase price or current market value.
- Formula: Cap rate = NOI ÷ Price
- Example: If NOI is $120,000 and price is $2,000,000, the cap rate is 6.0 percent.
Cap rate is a snapshot. It does not include your financing terms, tax situation, appreciation, future rent growth, or upcoming capital projects. Use it as a starting point, then build a full pro forma.
What counts in NOI
NOI starts with income and subtracts ongoing operating costs.
- Effective Gross Income: rental income after vacancy and credit loss, plus other income like parking or laundry.
- Operating Expenses: property management, repairs and maintenance, insurance, owner-paid utilities, property taxes, licenses, and any HOA dues.
- Excludes: mortgage payments, large capital expenditures, depreciation, and income taxes.
Always confirm how the seller calculated NOI. Owners may treat vacancy, utilities, or reserves differently, which can change the cap rate.
North Park drivers that move cap rates
North Park is a central San Diego neighborhood with strong walkability, a mix of restaurants and cultural spots, and proximity to Balboa Park, transit corridors, and major employment centers. These features help support renter demand relative to some outlying areas.
Several local factors influence cap rates here:
- Rent growth and vacancy: Faster rent growth and lower vacancy tend to compress cap rates. Slower growth or rising vacancy can expand them.
- Supply pipeline: New infill projects can moderate rent growth and affect pricing expectations.
- Operating costs: Property taxes at sale, insurance, utilities, and labor will shape expense ratios and NOI.
- Interest rates and lending: Cap rates often track broader real estate yields and debt costs with a lag.
- Regulations: Statewide tenant protections, such as AB 1482, and any local measures can influence revenue upside and risk.
- Building age and CapEx: Many North Park buildings are older vintage, which can mean more near-term capital needs unless renovations were completed.
Estimate current cap rates in North Park
You can pin down a realistic cap-rate view by following a simple, repeatable process.
1) Gather local sales comps
Focus on multifamily transactions in North Park or directly comparable central submarkets. Look at the last 6 to 12 months. If sales are sparse, expand the timeframe and adjust for market drift.
2) Normalize NOI and calculate implied caps
Pull rent rolls and operating statements where available. If you only have top-line data, estimate expenses using typical ratios for the asset type. Compute the implied cap rate as stabilized NOI divided by sale price.
3) Adjust for differences
Compare class, age, unit mix, recent renovations, parking, in-place rents per unit, occupancy, and lot or building size. Adjust your implied cap rates up or down to reflect risk, upside, and condition.
4) Consider financing and macro inputs
Check today’s mortgage rates and lender spreads. When debt costs rise, cap rates often follow. Also consider rent growth expectations in North Park. Strong demand in infill neighborhoods may justify lower current yields for some investors.
5) Report a range, not a single number
Given property differences, present a band by asset profile. For example, smaller, older buildings may trade differently than newer infill product. Use your comp set to define the range and note the period you analyzed.
6) Document assumptions
Show your vacancy rate, expense ratio, reserves, and any adjustments for taxes at sale. Clear assumptions make your estimate more defensible.
Underwriting guardrails to sanity-check your math
When you build or review NOI, these benchmarks can help, though you should verify with recent local statements:
- Expense ratio: Many multifamily assets run roughly 30 to 50 percent of effective gross income, depending on utilities and services provided.
- Vacancy and credit loss: Often 3 to 8 percent, depending on the submarket and unit mix.
- Reserves for replacements: Commonly $250 to $600 or more per unit per year for older buildings.
- Property taxes: In California, assessed value is typically reset at sale. Prop 13 limits annual increases thereafter, which affects pro forma expenses.
- Insurance: Coastal and California markets can see higher premiums. Review recent quotes to avoid surprises.
Quick scenarios that show sensitivity
Small changes in NOI or price can move cap rates more than you expect.
- Example A, NOI shift: Price is $2,000,000. If NOI is $120,000, cap is 6.0 percent. If NOI slips to $110,000 after you normalize expenses, the cap rate falls to 5.5 percent at the same price.
- Example B, price shift: If normalized NOI is $120,000 and you negotiate the price to $1,900,000, the cap rate rises to about 6.3 percent.
Remember, cap rate is unlevered. Financing changes your cash-on-cash and IRR, not the cap rate itself.
Common pitfalls to avoid
- Mixing T12 with pro forma: Compare like with like when you compute NOI.
- Ignoring taxes at sale: Reassessed property taxes can materially change expenses.
- Underestimating CapEx: Older North Park buildings often need systems, roofs, or unit upgrades.
- Overlooking utilities: Who pays water, sewer, trash, gas, and electric affects expenses and rent levels.
- Comparing apples to oranges: Do not compare a renovated infill building to an unrenovated vintage asset without adjustments.
- Skipping regulatory review: Understand how statewide tenant protections could apply to the property’s rent path and risk.
