How much house can I afford with two incomes?

With combined income, you can generally afford a home 3-5x your gross household income. A couple earning $150,000 combined can typically afford $450,000-$750,000 depending on debt, down payment, and interest rates.

Do lenders combine both incomes for mortgage approval?

Yes, lenders combine both incomes when both borrowers are on the loan application. Both credit scores matter, and lenders typically use the lower score for rate determination.

How Lenders Calculate Dual Income Affordability

Factor	How It’s Calculated
Gross income	Both incomes combined
DTI (Debt-to-Income)	Total monthly debts ÷ Combined gross monthly income
Front-end DTI	Housing costs only ÷ Income (target: ≤28%)
Back-end DTI	All debts ÷ Income (target: ≤36-43%)
Credit score	Lower of two scores often used for rate

DTI Examples

Combined Income	Monthly Gross	Max Housing (28%)	Max All Debt (36%)
$100,000	$8,333	$2,333	$3,000
$150,000	$12,500	$3,500	$4,500
$200,000	$16,667	$4,667	$6,000
$250,000	$20,833	$5,833	$7,500

Impact of Existing Debt on Buying Power

Combined income: $150,000

Monthly Debt	Max Home Price	Reduction
$0	$570,000	—
$500 (car)	$495,000	-$75,000
$1,000 (car + student loans)	$420,000	-$150,000
$1,500 (multiple debts)	$345,000	-$225,000
$2,000	$270,000	-$300,000

Each $500/month in debt reduces buying power by ~$75,000.

Down Payment Impact

Combined income: $150,000, targeting $500,000 home:

Down Payment	Loan Amount	Monthly Payment*	PMI
3% ($15,000)	$485,000	$3,230 + $320 PMI	Yes
5% ($25,000)	$475,000	$3,160 + $280 PMI	Yes
10% ($50,000)	$450,000	$3,000 + $190 PMI	Yes
20% ($100,000)	$400,000	$2,660	No

Principal + Interest at 7%

Single vs. Dual Income Comparison

Scenario	Income	Max Home	Monthly Payment
Single earner: $100K	$100,000	$380,000	$2,330
Dual: $60K + $40K	$100,000	$380,000	$2,330
Single earner: $150K	$150,000	$570,000	$3,500
Dual: $100K + $50K	$150,000	$570,000	$3,500

Same combined income = same buying power, but dual income provides more stability.

Risk Considerations for Dual Income Buyers

Conservative Approach

Strategy	Benefit
Qualify on one income only	Could survive job loss
Buy at 2.5-3x combined income	Very manageable payments
Keep total debt under 25%	Large financial cushion
6-month emergency fund	Weather any storm

Moderate Approach

Strategy	Benefit
Qualify on both incomes	Access more home
Buy at 3-4x combined income	Comfortable but not stretched
Keep total debt under 33%	Some cushion
3-month emergency fund	Basic protection

What to Avoid

Risk	Why It’s Dangerous
Buying at 5x+ income	No room for error
Counting bonuses as guaranteed	Variable income is variable
Ignoring career risk	Tech layoffs, industry changes
No emergency fund	One bad month = crisis

One Income Currently? Planning for Two

If currently single-income but expect second income:

Current Setup	Future Combined	Strategy
$80K single, adding $50K spouse	$130K combined	Qualify now on $80K for $300K home, or wait
$60K single, adding $60K spouse	$120K combined	Waiting doubles your buying power
$100K single, adding $40K part-time	$140K combined	Modest increase, may not be worth waiting

Lender note: New job income may need 2 years history for full counting; discuss with your lender.
