How Home Affordability Works

28% / 36% Rule

Industry standard for housing costs and total debt ratios

Key Financial Ratios:

Front-End Ratio (Housing Ratio)

Your total housing payment (mortgage, taxes, insurance, HOA) divided by gross monthly income. Lenders prefer this to be 28% or less. This ensures housing costs remain manageable relative to your income.

Back-End Ratio (Total Debt Ratio)

Your housing payment plus all other monthly debts (credit cards, auto loans, student loans) divided by gross monthly income. Lenders prefer this to be 36% or less. This ensures you have adequate income for other expenses.

Down Payment Impact

Your available down payment directly affects the loan amount needed and monthly payments. Larger down payments reduce monthly costs and may eliminate private mortgage insurance (PMI) requirements.

Factors Affecting Home Affordability

Income and Employment

Your gross monthly income is the foundation of affordability calculations.

Include: Base salary, bonuses, commission, overtime, rental income
Employment stability: Lenders prefer 2+ years of consistent employment
Income documentation: Pay stubs, tax returns, employment verification

Existing Debt Obligations

All monthly debt payments impact your borrowing capacity.

Credit cards, auto loans, student loans, personal loans, alimony
Minimum payments: Use actual monthly minimum payments required
Debt reduction: Paying off debts before applying improves affordability

Property-Related Costs

Housing costs extend beyond the mortgage payment.

Property taxes, homeowners insurance, HOA fees, PMI
Regional variation: Property taxes vary significantly by location
Insurance costs: Varies by location, property value, and coverage

Market Conditions and Timing

Interest Rate Impact

Rate Changes

A 1% interest rate change can affect affordability by 10-15% due to monthly payment impact

Rate Shopping

Compare rates from multiple lenders within 14-45 days to minimize credit impact

Rate Lock

Lock your rate when you find a good deal to protect against increases during processing

Local Market Factors

Property Values

Local market conditions affect both purchase prices and property tax assessments

Competition

Hot markets may require higher down payments or waiving contingencies

Timing Strategy

Consider seasonal patterns and personal financial readiness before house hunting

Affordability Examples

Example 1: First-Time Buyer

Monthly Income: $6,000 | Debts: $400 | Down Payment: $30,000

Maximum housing payment: $6,000 × 28% = $1,680
Maximum total debt: $6,000 × 36% = $2,160
Available for housing: $2,160 - $400 = $1,760
Limiting factor: $1,680 (28% rule)
Estimated max home price: ~$285,000

Result: Well-qualified with room for additional expenses

Example 2: High Debt Scenario

Monthly Income: $8,000 | Debts: $1,200 | Down Payment: $50,000

Maximum housing payment: $8,000 × 28% = $2,240
Maximum total debt: $8,000 × 36% = $2,880
Available for housing: $2,880 - $1,200 = $1,680
Limiting factor: $1,680 (36% rule due to existing debt)
Recommendation: Pay down debt first

Result: Existing debt limits affordability significantly

Example 3: Strong Financial Position

Monthly Income: $10,000 | Debts: $200 | Down Payment: $100,000

Maximum housing payment: $10,000 × 28% = $2,800
Maximum total debt: $10,000 × 36% = $3,600
Available for housing: $3,600 - $200 = $3,400
Limiting factor: $2,800 (28% rule)
Estimated max home price: ~$525,000

Result: Excellent position with flexibility for premium properties
