What income do I use to calculate my budget?
Lenders base approval on your gross monthly income (GMI)—your pay before taxes and deductions.
- Include base salary and consistent bonuses/commissions (if documented for 2+ years)
- Self-employed? Use average of last 2 years' tax returns
- Multiple income sources? Add them all together
Use only reliable, documented income. Lenders verify everything, so stick to income you can prove.
How do I calculate my current monthly debt obligations?
List all minimum monthly payments that appear on your credit report:
- Auto loans: Monthly payment amount
- Student loans: Minimum payment (even if deferred)
- Credit cards: Minimum payment only, not current balance
- Personal loans: Monthly payment
- Child support/alimony: Court-ordered amounts
Use minimum payments only. What you actually pay extra doesn't matter for qualification—lenders only count required minimums.
What debt-to-income ratio should I target in Maricopa?
DTI measures how much of your income goes to debt payments. Lower ratios = stronger offers and better rates.
Conservative Planning Targets
| DTI Type | Target % | What It Covers |
|---|---|---|
| Front-end | 28% | Housing payment only |
| Back-end | 36% | All monthly debts |
Quick DTI Formulas
Front-end DTI = Housing Payment ÷ GMI
Back-end DTI = (Housing + Other Debts) ÷ GMI
Maximum DTI varies by loan program. Conventional loans often allow up to 45% back-end, but lower is always better for approval odds.
Aim for 28% housing DTI. This leaves room for savings, emergencies, and lifestyle—not just loan approval.
How much cash do I need for down payment and closing?
Your cash requirements directly impact both your monthly payment and total purchase price.
- Down payment options: 3% (conventional), 3.5% (FHA), 0% (VA/USDA), or 10-20% (better rates)
- Closing costs: Typically 2-4% of purchase price in Maricopa
- Prepaid items: Property taxes, insurance, interest (varies by closing date)
Know your available cash upfront. Higher down payments = lower monthly payments but require more cash at closing.
What are the specific monthly costs in Maricopa?
Your monthly housing payment includes more than just principal and interest. Here's what to expect in Maricopa:
Required Monthly Costs
- Principal & Interest (P&I): Your mortgage payment
- Property taxes: Collected monthly in escrow
- Homeowners insurance: Required by lender
- PMI/MIP: If down payment < 20%
Maricopa-Specific Costs
- HOA fees: Most communities have monthly dues
- Utilities:
- Electric District 3 (ED3)
- Global Water
- Southwest Gas
Budget for the full payment. HOA fees in Maricopa communities can range from $50-300+ monthly depending on amenities.
How do Maricopa neighborhoods compare for budget planning?
Price ranges and HOA fees vary significantly by community. Research neighborhoods that fit your budget and lifestyle:
Check current pricing with our Market Snapshot for up-to-date trends and inventory levels.
Compare total monthly costs by neighborhood. A lower purchase price with high HOA fees might cost more monthly than a higher-priced home with low fees.
What's the step-by-step budget calculation process?
Follow this sequence to convert income and debts into a shopping price range:
- Calculate GMI: Annual Income ÷ 12
- Sum current debts: Add all minimum monthly payments
- Set DTI target: 28% for housing is conservative
- Find max housing payment: GMI × 28% = Max Housing Budget
- Subtract non-mortgage costs: Max Housing - (Taxes + Insurance + HOA) = Available for P&I
- Calculate loan amount: Use mortgage calculator with current rates
- Add down payment: Loan Amount ÷ (1 - Down Payment %) = Purchase Price
- Verify cash needs: Ensure you have down payment + closing costs + reserves
Work backwards from neighborhoods you like. Find typical HOA/tax costs, then see what purchase price fits your payment comfort zone.
Can you show me a real budget example?
Example calculation for illustration—use current rates and your specific numbers:
Sample Scenario:
- Annual income: $90,000 → GMI = $7,500
- Current monthly debts: $650 (car + student loans)
- Target housing DTI: 28% → Max housing = $2,100
- Estimated taxes/insurance/HOA: $400
- Available for P&I: $1,700
Use the calculator to see what loan amount $1,700 supports at today's rates.

Frequently Asked Questions
Should I get pre-qualified or pre-approved?
Pre-approved. Pre-qualification is just an estimate. Pre-approval involves credit checks and income verification, giving you a firm budget and stronger negotiating position.
What if my DTI is higher than 36%?
You may still qualify, but consider paying down debt first or looking at lower price ranges. Higher DTI = higher risk if income changes.
Is Maricopa really more affordable than Phoenix?
Generally yes, but check current data rather than assuming. Market conditions change, and some Maricopa communities compete directly with Phoenix suburbs on price.
How much should I keep in reserves after closing?
Plan for 2-6 months of total housing payments as an emergency fund. New homeowners often face unexpected repairs or utility deposits.
