With Collin County Property Taxes Eating 1.8-2.2% of My Home's Value Every Year, Does Buying a Rental in McKinney Actually Cash Flow in 2026?

With Collin County property taxes eating 1.8-2.2% of my home's value every year, does buying a rental in McKinney actually cash flow in 2026? Sometimes, but only if you underwrite the property tax bill and insurance premium as real, non-negotiable line items before you fall in love with the rent estimate.

McKinney has been a popular target for rental buyers for years, and the logic makes sense on the surface: solid population growth, strong tenant demand, and homes that have appreciated steadily. But 2026 is a different environment than 2019 or even 2022. Property tax bills in Collin County have climbed alongside home values, and without a homestead exemption to soften the blow, an investment property gets taxed on a larger share of its assessed value than the house you actually live in. Add in insurance premiums that have jumped noticeably across North Texas in the last couple of years, and the math that used to work on a $400,000 rental in Craig Ranch or Trinity Falls doesn't automatically work today.

This doesn't mean rentals in McKinney are a bad idea. It means the spreadsheet has to be honest. You need real numbers for taxes, insurance, vacancy, and maintenance rather than the optimistic defaults a lot of online rental calculators use. Some price points and property types still cash flow reasonably well. Others only work if you're banking on appreciation rather than monthly income, which is a fine strategy but a different one. The rest of this post walks through where the tax and insurance numbers actually land, which parts of Collin County still make sense for cash flow, and where you're more likely buying for equity growth than for rent checks.

Why Collin County Taxes Hit Rentals Harder Than Owner-Occupied Homes

The 1.8-2.2% figure people quote for Collin County isn't a flat rate set by one office. It's the combined effect of the county rate, McKinney's city rate, school district rate, and any special districts layered on top, applied to your home's appraised value. If you live in the home, a homestead exemption knocks a chunk off that taxable value and caps how fast your appraisal can rise each year. A rental doesn't get either benefit. That means an investment property in McKinney can carry a materially higher effective tax rate than the house next door where the owner lives full time.

Before you run any cash flow numbers, confirm the county's appraised value for the property is actually accurate. Overstated square footage or an outdated condition rating can inflate your tax bill for years. If you already own a McKinney property or are evaluating one, it's worth checking how Collin CAD's records compare to reality before you close or before your next bill arrives.

Insurance Is the Other Number People Underestimate

Property tax gets all the attention, but insurance has quietly become the bigger swing factor in a lot of McKinney rental underwriting. Premiums have risen sharply across Collin County due to hail and severe weather claims, and landlord policies often cost more than a comparable owner-occupied policy. If you're pulling last year's insurance quote to run this year's numbers, you're probably underestimating your expenses. It's worth reading up on why McKinney renewals have jumped so much lately so you're budgeting a realistic premium rather than a stale one.

What the Actual Cash Flow Math Looks Like

Run a simple exercise on a McKinney rental in the $400,000-$500,000 range: at a 2% combined effective tax rate, you're looking at roughly $8,000-$10,000 a year in property taxes alone, before insurance, before a mortgage payment, before vacancy or repairs. On many single-family rentals in neighborhoods like Stonebridge Ranch or Eldorado, market rent doesn't fully absorb that load once you add debt service on top.

Where the math tends to work better:

• Lower-priced, older McKinney homes where the purchase price is well below new construction, keeping both the tax basis and the mortgage smaller
• Properties bought with a larger down payment or paid off outright, since the tax and insurance drag matters most when it's stacked on a full mortgage payment
• Homes in areas where rent has kept pace with or outrun typical Collin County tax growth, rather than newer master-planned sections where rents lag the premium buyers paid for the neighborhood

Where it's tougher: new construction in higher-tax special districts, luxury rentals above $600,000 where rent doesn't scale proportionally with price, and any property bought at peak comps with minimal equity cushion.

Don't Ignore Appreciation and Equity Growth

Cash flow is one measure of return, not the only one. Collin County has had strong long-term appreciation, and a McKinney rental that breaks even or runs slightly negative monthly can still be a solid investment once you factor in principal paydown and equity growth. The question is whether you're comfortable carrying a property that doesn't produce income today in exchange for a bet on tomorrow's value. That's a legitimate strategy for some buyers and a dealbreaker for others, and it's worth being honest with yourself about which camp you're in before you make an offer.

Building a Realistic Worksheet

The mistake most rental buyers make in Collin County right now is using national or generic rules of thumb, like the 1% rule, without adjusting for local tax and insurance realities. A worksheet built specifically around McKinney's tax rates, typical insurance quotes, and current rents gives you a far more honest picture than a generic online calculator.

FAQ

Do all McKinney neighborhoods carry the same tax rate?

No. Total tax rates vary based on the specific city, school district, and any special districts (like a PID or MUD) tied to the property, so two homes of similar value in different parts of McKinney or Collin County can have noticeably different tax bills.

Is a homestead exemption available on a rental property?

Generally no. Homestead exemptions apply to your primary residence, which is a big part of why investment properties carry a heavier effective tax burden than owner-occupied homes in the same area.

Should I focus on cash flow or appreciation when buying a McKinney rental?

It depends on your goals and holding period. Some investors accept thin or negative monthly cash flow in exchange for long-term equity growth in a fast-growing area like Collin County, while others need positive monthly income and should underwrite accordingly before purchasing.
