Mortgage vs Rent: Should You Buy or Keep Renting?

The buy-vs-rent decision depends on more than monthly payment comparison. Buying builds equity but includes property taxes, maintenance, and closing costs. Renting offers flexibility and lower upfront costs but builds no equity. The "5-year rule" suggests buying makes financial sense only if you plan to stay 5+ years.

Break-Even Calculation Example

Home price: $400,000 | Down payment: 20% ($80,000)
Mortgage: $320,000 at 6.5% for 30 years

Monthly costs (buying):
• Mortgage payment: $2,022
• Property tax (1.2%): $400
• Insurance: $150
• Maintenance (1%): $333
• Total: ~$2,905/month

Comparable rent: $2,200/month

The renter saves $705/month ($8,460/year) but builds no equity.
After 5 years:
• Buyer equity: ~$30,000 (principal paid) + appreciation
• Buyer closing/selling costs: ~$30,000
• Break-even: ~5-6 years if home appreciates 3%/year

If you plan to stay less than 5 years, renting is usually cheaper. If you plan to stay 7+ years and can afford the down payment, buying typically wins due to equity buildup and appreciation.

PMI and Property Taxes: What Homebuyers Need to Know

Private Mortgage Insurance (PMI) and property taxes are two of the most overlooked costs in homeownership. PMI protects the lender — not you — and is required when your down payment is less than 20% of the home's purchase price. Property taxes are levied by local governments based on your home's assessed value and can vary dramatically from state to state. Together, these two costs can add hundreds — even thousands — of dollars to your monthly housing payment.

Down Payment %PMI Required?Typical Monthly CostImpact on $300K Home
Under 5%Yes$200-450/month+$200-450/mo
5-10%Yes$150-300/month+$150-300/mo
10-15%Yes$100-200/month+$100-200/mo
15-20%Yes$50-100/month+$50-100/mo

Property Tax by State

StateAvg. Effective RateAnnual Tax on $300K Home
New Jersey2.23%$6,690
Texas1.60%$4,800
New York1.62%$4,860
California0.75%$2,250
Hawaii0.28%$840
National Average0.99%$2,970

You can eliminate PMI once you reach 20% equity in your home. You can request cancellation once your equity reaches 20%, and the lender must automatically terminate PMI when your equity reaches 22% (under the Homeowners Protection Act). Making extra payments or improving your home's value can help you reach the 20% threshold faster. Property taxes, however, are a permanent cost — though you can appeal your home's assessed value if you believe it is overvalued.

Extra Mortgage Payment Strategies: How Much Can You Save?

Adding even a small amount to your monthly mortgage payment can dramatically reduce the total interest you pay over the life of the loan and shorten your payoff timeline. Because mortgage interest is front-loaded (amortization), extra payments go directly toward reducing your principal balance, which in turn reduces the interest that accrues on every subsequent payment. The earlier you start making extra payments, the greater the impact.

Extra Payment/MonthYears Saved (30yr Loan)Interest Saved on $300K at 6.5%
$502.5 years~$28,000
$1004.5 years~$50,000
$2007.5 years~$82,000
$50012 years~$130,000
$1,00017 years~$170,000

Payment Strategies

StrategyHow It WorksAnnual ExtraBest For
BiweeklyHalf payment every 2 weeks (26 payments = 13 full payments)1 extra payment/yearSteady income
Monthly ExtraAdd fixed amount to each paymentVariesBudget-conscious
Annual Lump SumOne extra payment per year1 full paymentBonus recipients
Refinance to 15yrSwitch to shorter termHigher required paymentLong-term owners

The key to meaningful savings is consistency. Even $50 per month can save you $28,000 in interest over the life of a $300,000 loan. Set up automatic extra payments so you never have to think about it — and make sure your lender applies the extra amount to the principal balance, not to next month's payment.
