On an $80,000 annual salary, buying a $300,000 home in Texas is a stretch — but it's achievable with good credit, minimal other debt, and a solid emergency fund. At 6.75% for 30 years with 10% down, your all-in monthly housing payment works out to approximately $2,426, representing 36.4% of your gross monthly income — right at the upper edge of conventional lending comfort zones.
Your Monthly Payment Breakdown
Here's exactly where your money goes each month on a $300,000 Texas home:
| Cost Component | Monthly Amount | |---|---| | Principal & Interest | $1,752 | | Property Tax (est. 1.6%, Travis County) | $400 | | Homeowners Insurance | $150 | | PMI (10% down) | $124 | | Total PITI | $2,426 |
After factoring in the federal mortgage interest deduction, your effective carrying cost drops to approximately $2,279/month — saving you roughly $147 each month through reduced federal tax liability. That $147/month compounds meaningfully over the early years of your mortgage when the interest portion of each payment is highest.
Texas Property Taxes: The Hidden Cost
Texas has no state income tax — a major financial advantage worth approximately $3,000–$5,000 per year compared to states like California or New York. However, the state partially offsets this with some of the highest property tax rates in the nation. In Travis County (Austin), the effective rate runs around 1.68%. In Harris County (Houston), it's closer to 1.84%. Even in comparatively lower-tax Collin County (Plano), you're looking at 1.54%.
On a $300,000 home, budget $380–$460 per month for property taxes alone. This figure is non-negotiable — unlike PMI, property taxes never disappear, and they typically increase as your home's assessed value rises over time.
One important protection: Texas's homestead exemption caps annual assessed value increases at 10% per year for primary residences. File within 60 days of closing and this protection takes effect immediately, shielding you from rapid assessment spikes in hot markets.
Federal Tax Benefit Analysis
At $80,000 income as a single filer, your federal marginal rate is 22%. Your first-year mortgage interest will be approximately $18,225 (calculated on a $270,000 starting balance at 6.75%). Combined with $4,800 in property taxes, your total itemizable deductions reach roughly $23,025.
Since the 2026 standard deduction for single filers is $15,000, itemizing saves you money — the $8,025 excess generates an annual federal tax saving of approximately $1,765 ($147/month). This benefit erodes gradually over the life of the loan as your balance falls and the interest portion of each payment shrinks, but it's most impactful in your first decade of ownership.
Debt-to-Income Ratio: The Approval Question
Your gross monthly income at $80,000/year is approximately $6,667. A $2,426 housing payment creates a front-end DTI of 36.4%. FHA guidelines allow up to 43% total DTI; conventional loans prefer under 36% on the front end.
To qualify comfortably, keep all other monthly debt payments — car loans, student loans, credit card minimums — under $250/month. If you carry $500/month in other debt, your total DTI reaches 43.8%, which is at the outer limit of FHA eligibility and likely declined by most conventional lenders.
The clearest path to easier approval: bump your down payment to 15–20% (reducing the loan amount and eliminating PMI), or target homes in the $265,000–$280,000 range where your DTI drops to a more comfortable 33–35%.
Rent vs. Buy in Texas: The Math
Current median rents in Texas's major markets run $1,700–$1,900/month for a comparable 3-bedroom home or apartment. Your all-in ownership cost of $2,426 is meaningfully higher than renting — the gap is real. But this comparison misses a critical piece: equity.
Each month, approximately $238 of your first payment reduces your mortgage balance. That number grows every year as the amortization schedule shifts toward principal. Combined with Texas's historical home appreciation of 3–5% annually in major metros, the financial break-even point — when buying becomes superior to equivalent renting — arrives at approximately year 5.
At 10 years, homeowners in this scenario are projected to be approximately $45,000 ahead in net worth compared to renters who invested their monthly savings in index funds. At 30 years, the homeowner advantage grows to approximately $220,000 — a powerful long-term case for ownership even at today's elevated mortgage rates.
PMI: Your Path to Savings
With 10% down, you'll pay PMI of $124/month until your loan-to-value ratio reaches 80% — approximately month 82 under standard payment schedules. You can accelerate this milestone by:
- Making extra principal payments to cross the 80% threshold faster
- Requesting a new appraisal if home values appreciate significantly (a 15% price gain would push you below 80% LTV automatically)
- Refinancing if rates improve and your equity position supports a lower-rate loan
Eliminating PMI saves $1,488/year — money that can redirect to accelerated principal paydown or investment.
What-If: Rate Sensitivity
At 6.75%, you're paying $1,752/month in principal and interest. If rates improve to 5.75%, refinancing would reduce your payment to approximately $1,576/month — saving $176/month and $63,360 over the remaining loan term. Set a rate alert and revisit refinancing when your break-even point (typically 18–24 months of savings to cover closing costs) makes sense.
The Bottom Line
A $300,000 Texas home on $80,000 income is achievable but leaves limited margin for financial error. You'll need a credit score above 720, minimal other monthly debt obligations, and ideally 3–6 months of housing expenses in an emergency fund after closing. If your situation is tight today, targeting the $265,000–$280,000 price range provides meaningful cash flow relief while keeping you in Texas's strong long-term appreciation market.
