You’ve found the perfect home in Arizona. It has the upgraded kitchen, the backyard oasis, and it’s in your dream neighborhood. You submit an offer, feeling confident, only to lose out to another buyer who came in with a pre-approval letter.
Getting pre-approved helps you understand exactly what you can afford and proves to sellers that you’re a serious buyer. Whether you’re a first-time buyer in Chandler or moving up to a larger home in Scottsdale, understanding the pre-approval process can save you time and stress—and give you the best chance of winning the bid on the home you want.
Here are the five essential things every Arizona homebuyer should know before starting their pre-approval journey.
1. Pre-Approval and Pre-Qualification Aren’t the Same
Many homebuyers use these terms interchangeably, but only one carries real weight with sellers.
What’s the difference between pre-qualification and pre-approval?
The key difference comes down to verification. Pre-qualification is an informal estimate based on what you tell a lender, while pre-approval involves verified documentation and underwriter review. Here’s how they compare:
Pre-qualification:
- Takes 15 to 30 minutes
- Based on self-reported information
- No document verification
- No credit check
- Provides a rough estimate only
Pre-approval:
- Usually takes one to three business days
- Requires full income and asset documentation
- Lender verifies all information
- Includes credit check and underwriting review
- Provides a conditional loan commitment
Why Arizona sellers care about the difference
Pre-approval demonstrates that you’ve already cleared the major financing hurdles. The seller knows your loan is far more likely to close, reducing their risk of the deal falling through.
Think of pre-qualification as checking your pockets to see if you have enough cash for dinner. Pre-approval is like having a confirmed reservation at the restaurant, with your credit card already on file and verified. One shows interest; the other shows commitment and capability.
Key takeaway: Always pursue pre-approval, not just pre-qualification, before you start seriously shopping for homes in Arizona. It transforms you from a window shopper into a serious buyer that sellers want to work with.
2. Gather Your Documentation Before You Apply
The pre-approval process moves faster when you’re organized and prepared from the start.
What documents do I need for mortgage pre-approval?
You’ll need to provide documentation that proves your income, assets, and identity. Here’s the paperwork you’ll need.
Required for all borrowers:
- Two years of federal tax returns (with all schedules and W-2s)
- Two most recent pay stubs
- Two months of bank statements (all accounts)
- Government-issued photo ID (driver’s license or passport)
- Employment verification authorization
Additional documents for self-employed borrowers:
- Two years of business tax returns
- Year-to-date profit and loss statement
- Business bank statements
- CPA letter (sometimes required)
How to organize your documents
Create a dedicated folder—physical or digital—for all your mortgage documents. Scan physical documents so you have digital copies ready to upload. Remove password protection from PDFs before sending them to your lender. Keep this folder updated throughout your home search, as you may need to provide fresh documents if your pre-approval expires.
Common documentation mistakes to avoid
Don’t submit blurry photos of documents. Ensure that all pages of your tax returns are included, since missing schedules delay approval. Don’t make large deposits or transfers right before applying, as these require explanation letters that slow the process.
You can use apps like Genius Scan to scan images and documents with clarity.
3. Understand Credit Scores and the Pre-Approval Process
Your credit score plays a starring role in mortgage pre-approval, but many buyers have misconceptions about how credit inquiries work.
Will getting pre-approved hurt my credit score?
Yes, but only minimally. Pre-approval creates a hard inquiry that may temporarily lower your score by 3 to 5 points.
Minimum credit score requirements by loan type
Different lenders and different loan programs have different credit requirements. Listed below are the program requirements of American Pacific Mortgage.
FHA loans:
- 580+ for 3.5% down payment
- However, if a borrower has no credit score, the application is handled through manual underwriting.
Conventional loans:
- 620 or per AUS findings
- 740+ for best interest rates
VA loans** (for eligible veterans):**
- 580+ for loan amounts less than or equal to $832,750
- Higher loan amounts require a higher credit score
Jumbo loans:
- 620+
- 740+ for best interest rates
- Higher scores may unlock better terms
You don’t need perfect credit to buy a home in Arizona. While the average Arizona homebuyer has a credit score in the mid-700s, many successful buyers fall in the 620–680 range and still secure favorable terms, especially with FHA financing.
Understanding the rate shopping window
Credit scoring models recognize that mortgage shopping is responsible financial behavior. Here’s how it works:
- Single inquiry impact: 3- to 5-point temporary drop
- Shopping window: 45 days to compare lenders
- All inquiries counted as one: Multiple mortgage applications within the window = one inquiry
- Recovery time: Score typically rebounds within a few months
Quick ways to improve your credit score
If your score needs a boost before applying, take these steps:
- Pay down credit card balances below 30% of limits
- Make all payments on time for at least six months
- Avoid applying for new credit
- Keep old credit cards active (don’t close the accounts)
- Dispute any errors on your credit report
Critical don’ts during your pre-approval period
Once you’re pre-approved, protect your loan status by avoiding:
- Large purchases on credit (cars, furniture, appliances)
- Opening new credit cards or loans
- Co-signing loans for friends or family
- Changing jobs or careers
- Making large cash deposits without documentation
Lenders recheck your credit and employment before closing. Any significant changes can delay or derail your loan approval.
4. Learn How Lenders Calculate Your Debt-to-Income Ratio
Lenders use your debt-to-income (DTI) ratio to determine borrowing limits:
- Calculation: Total monthly debt payments ÷ gross monthly income
- Conventional loans: Up to 43% DTI (some go higher)
- FHA loans: Up to 50% DTI in some cases
The reality check: A 43% DTI means 43% of your gross income goes to debt payments before taxes. What’s left must cover groceries, utilities, car insurance, healthcare, entertainment, and savings.
A smarter approach: The 28/36 Rule
Financial advisers recommend a more conservative budget:
- 28% to 30% maximum for housing costs (principal, interest, taxes, insurance, HOA)
- 36% maximum for total debt payments
This approach leaves breathing room for life’s expenses and unexpected costs.
Additional homeownership costs
Budget for these Arizona-specific expenses.
Utilities:
- Summer electric bills: $300 to $500+ during peak months
- Year-round water for landscaping
HOA fees:
- Range from $50 to $500+ monthly
- Vary significantly by neighborhood
Property taxes:
- Moderate compared with many other states
- Still add $200 to $500+ monthly, depending on home value
Insurance:
- Homeowners insurance
- Higher premiums in areas with extreme weather risks
Maintenance unique to Arizona:
- HVAC maintenance and eventual replacement (critical in a desert climate)
- Desert landscaping and irrigation systems
- Pest control services
- Pool maintenance (if applicable)
- Annual maintenance typically costs 1% to 3% of home value
Real-world budget example
Let’s look at a $500,000 loan at 6.5% interest:
| Expense | Monthly Cost |
| Principal and interest | $3,160 |
| Property taxes | $400 |
| Homeowners insurance | $150 |
| HOA fees | $100 |
| Total housing payment | $3,810 |
To follow the 28% rule, you’d need a gross monthly income of $13,600 ($163,200 annually).
But ask yourself: Should you spend $3,810 per month on housing just because you can? Consider your other financial goals, existing debts, and desired lifestyle first.
Why you need financial breathing room
Your mortgage payment is predictable, but life isn’t.
Factors that fluctuate:
- Medical emergencies
- Car repairs
- Home repairs (AC units don’t break on schedule)
- Family emergencies
- Job changes or income reductions
Your fixed mortgage payment doesn’t adjust for these realities. Keeping your housing costs comfortably below your maximum approval helps you:
- Build emergency savings
- Maintain your quality of life
- Weather unexpected expenses
- Achieve other financial goals
- Sleep better at night
5. Understand Arizona Programs for First-Time Buyers
Arizona provides several programs designed to make homeownership more accessible and affordable for first-time buyers.
What first-time homebuyer programs are available in Arizona?
Arizona provides several programs to help first-time buyers overcome the down payment hurdle. The Arizona Department of Housing offers the Home Plus program with up to $7,500 in down payment assistance, plus competitive interest rates. Additional county-specific programs in Maricopa and Pinal counties can provide even more support.
Who qualifies as a first-time buyer in Arizona?
Arizona’s definition is more generous than you might think:
- Haven’t owned a primary residence in the past three years.
- Previously owned a home? You still qualify if it’s been three or more years.
- Veterans and displaced homemakers may have additional exceptions.
The Home Plus Program: Key benefits
Down payment assistance:
- Assistance is typically 3% to 5% of the total first mortgage loan amount (which can be more or less than $7,500 depending on the loan size).
- Comes as a second lien at 0% interest.
- No monthly payment required.
- A very common forgiveness term is three years (forgiven monthly over 36 months, or 1/36th per month). Other program options may have five or more years.
Loan compatibility:
- Works with FHA loans
- Works with VA loans
- Works with USDA loans
- Works with conventional loans
Program limits you should know

Frequently Asked Questions
How long does pre-approval take?
Pre-approval typically takes three to 10 business days, depending on how quickly you provide documentation and the lender’s current volume. Some lenders offer expedited pre-approvals in 24 to 48 hours.
How long is my pre-approval letter valid?
Most pre-approval letters are valid for 60 to 90 days. If your home search extends beyond that, you’ll need to update your documentation and refresh your pre-approval.
What happens if my financial situation changes?
If your financial situation changes, contact your lender immediately. Job changes, new debts, or changes in income can affect your approval. Your lender can advise whether the changes impact your loan and what documentation is needed.
Do I need pre-approval to look at homes?
No, you don’t need a pre-approval letter to look at homes. However, serious home shopping is more productive with pre-approval. You’ll know your true budget, and real estate agents prioritize showing homes to pre-approved buyers who are ready to make offers.
