How Much House Can You Afford on a $100,000 Salary? (2026)

Six figures unlocks a lot of the US housing market. At $100,000, you have meaningful options in most metros — here’s the complete 2026 affordability breakdown.

The 28% Rule at $100,000

$100,000 ÷ 12 = $8,333/month gross $8,333 × 28% = $2,333/month maximum PITI

This is your total monthly housing budget including principal, interest, property taxes, and insurance.

From $2,333/month to a Home Price

Subtract the non-mortgage portions of PITI:

Component	Monthly Estimate	Basis
Property taxes	~$290	1.1% on $315k home
Homeowner’s insurance	~$150	~$1,800/year
PMI (with 20% down)	$0	Eliminated
P&I Budget	~$1,893

At 7%, 30-year fixed, $1,893/month P&I: → Maximum loan: ~$284,000 → With 20% down: ~$355,000 home price

Allowing for comfort margin and rounding: $315,000-$335,000 is the practical target.

Stress Test: 8% Rate Scenario

Rate	P&I Budget	Max Loan	20% Down → Price
6.5%	$1,893	~$298,000	~$373,000
7.0%	$1,893	~$284,000	~$355,000
7.5%	$1,893	~$271,000	~$339,000
8.0%	$1,893	~$259,000	~$324,000

If rates move to 8%, your comfortable purchase price drops from ~$355k to ~$324k — a $31,000 difference. This is why locking a rate quickly matters in volatile rate environments.

43% DTI Rule: Approval Ceiling

$8,333 × 43% = $3,583/month total debt allowance

Other Monthly Debt	Housing Budget	Max Loan (7%)	Max Home (20% down)
$0	$3,583	~$537,000	~$672,000
$400	$3,183	~$477,000	~$596,000
$700	$2,883	~$432,000	~$540,000
$1,000	$2,583	~$387,000	~$484,000

These are approval maximums, not affordability targets. At 43% DTI, housing consumes so much of your income that emergencies become financial crises.

Down Payment Requirements

For a $315,000 home:

Option	Down Amount	Monthly PMI	Break-Even on 20%?
3% conventional	$9,450	~$222/mo	~9 years
5%	$15,750	~$200/mo	~7 years
10%	$31,500	~$111/mo	~4 years
20%	$63,000	$0	Immediate

On a $100,000 salary in Texas (take-home ~$6,561/month), saving $1,500/month reaches 20% down on a $315,000 home in about 3.5 years. Saving $2,000/month: under 2.5 years.

Building Wealth While Owning

At $100,000, the 401(k) contribution limit for 2026 is $23,500 — 23.5% of gross salary. After buying a home in this range, you should still be able to:

• Max your 401(k) employer match (typically 3-6%)
• Contribute $500-$1,000/month to retirement
• Maintain a 3-6 month emergency fund
• Avoid financial fragility from the mortgage payment

This balance is harder to maintain if you buy at the 43% DTI limit.
