What Is a Conventional Loan in Arizona?

When someone asks what kind of loan they should get, the first question I ask back is: what does your down payment look like? Not because I am trying to screen them out, but because that one number shapes almost everything else. Your loan type, your monthly payment, whether you will pay mortgage insurance, and for how long. Getting it right early means you are making an offer from a position of clarity instead of guessing from the sidelines while the house goes to someone else.

For most Arizona buyers, a conventional loan is the answer. It is not government-backed, it follows guidelines set by Fannie Mae and Freddie Mac, and it is designed for buyers who have reasonable credit and can bring some equity to the table. In Scottsdale and the broader Phoenix metro, where the entry-level market starts well above $400,000 in most neighborhoods, understanding the conventional loan is not a nice-to-have. It is the foundation of your home-buying plan. The 2026 conforming loan limit for Arizona counties including Maricopa, Pima, and Pinal sits at $832,750 (FHFA). That means most buyers in Scottsdale proper can still use conventional financing rather than stepping into jumbo territory.

The sections below cover everything a conventional loan is, how much down payment you actually need, what your credit score determines, how PMI works and when it goes away, and how conventional stacks up against FHA when you run the real numbers. By the end you will know exactly where you stand and what your next move should be.

What a Conventional Loan Actually Is

The definition is simpler than people expect. A conventional loan is any mortgage that is not insured or guaranteed by a federal government program. That puts it in contrast to FHA loans (Federal Housing Administration), VA loans (Department of Veterans Affairs), and USDA loans (Department of Agriculture). None of those government programs back a conventional loan. Instead, the risk is taken on by private lenders, and in exchange those lenders follow the guidelines set by Fannie Mae (Federal National Mortgage Association) and Freddie Mac (Federal Home Loan Mortgage Corporation). Fannie and Freddie are government-sponsored enterprises that purchase mortgages from lenders, freeing up capital so lenders can make new loans. Their guidelines define what a conforming conventional loan looks like.

Following those guidelines is what makes a loan eligible to be sold in the secondary mortgage market. Lenders care about this because holding every loan they write on their own books would tie up capital fast. By writing loans that conform to Fannie and Freddie guidelines, they can sell those loans and issue new ones. This is the machinery behind nearly every conventional mortgage in America, including the ones written right here in Scottsdale and the Phoenix metro.

What that means practically for a borrower is that conventional loans tend to be more flexible than their government-backed counterparts. You have more options on down payment, more control over mortgage insurance, and more loan term choices. The tradeoff is that conventional loans typically require stronger credit and a slightly larger down payment compared to FHA. But for a buyer who meets the standards, the long-run savings are often significant.

The two main flavors are fixed-rate and adjustable-rate. A 30-year fixed is by far the most popular choice for Arizona buyers in 2026, because it locks your payment for the life of the loan and removes the interest-rate risk that an ARM carries. Fifteen-year fixed loans cost less in total interest but have higher monthly payments. Most buyers choose 30-year fixed. The right answer depends on your time horizon, monthly budget, and how long you expect to own the home. For a buyer planning to stay at least seven years in Scottsdale, a 30-year fixed conventional loan is almost always the starting point.

Conforming vs. Jumbo in Arizona: The $832,750 Line

Every year the Federal Housing Finance Agency (FHFA) publishes updated conforming loan limits. For 2026, the baseline limit for most Arizona counties is $832,750. A conventional loan at or below that amount is a conforming loan. A conventional loan above that amount is a non-conforming loan, which most people call a jumbo loan.

The conforming limit matters more than most buyers realize. On the conforming side, your lender can sell the loan to Fannie Mae or Freddie Mac, which keeps interest rates lower and underwriting standards more predictable. On the jumbo side, your lender holds the loan or sells it in a private secondary market, which typically means stricter requirements: a higher credit score (often 700+), more months of cash reserves, and sometimes a larger down payment. Rates on jumbo loans have historically run close to conforming rates, but underwriting is less forgiving.

The practical implication for Scottsdale buyers is straightforward. A home priced at $900,000 with 10% down produces a loan of $810,000, which is still inside the conforming limit. A home priced at $950,000 with 10% down produces a loan of $855,000, which crosses the line. One buyer gets conforming pricing; the other jumps into jumbo. The house is only $50,000 more expensive, but the financing category shifts entirely. Knowing where the line sits lets you plan accordingly, whether that means making a slightly larger down payment to stay conforming, or knowing in advance that you are looking at jumbo terms.

Purchase Price	Down Payment (10%)	Loan Amount	Loan Category (2026)
$500,000	$50,000	$450,000	Conforming Conventional
$750,000	$75,000	$675,000	Conforming Conventional
$850,000	$85,000	$765,000	Conforming Conventional
$950,000	$95,000	$855,000	Jumbo (exceeds $832,750)
$1,200,000	$120,000	$1,080,000	Jumbo

For most Arizona buyers purchasing homes priced between $400,000 and $900,000 with a 10% or larger down payment, the 2026 conforming limit of $832,750 keeps them squarely in standard conventional territory.

What Is the Down Payment for a Conventional Loan in Arizona?

The 20% down payment is a myth in its most extreme form. Yes, putting 20% down eliminates PMI and often gets you the best rate. But conventional loans do not require 20% down. The actual minimum depends on which program you qualify for and what your lender requires.

Fannie Mae HomeReady and Freddie Mac Home Possible both allow 3% down payments for qualifying buyers. HomeReady is designed for low-to-moderate income borrowers whose income does not exceed 80% of the area median income (AMI) for the county where the home sits. It allows income from boarders and family members in the household to count toward qualifying, and gift funds and down payment assistance programs are permitted as the source. Home Possible has a similar income structure and was built for buyers who need maximum flexibility in how they fund the down payment. Both programs require completion of homeownership education for first-time buyers.

Standard conventional loans without the HomeReady or Home Possible overlay typically require at least 5% down. At 10% down you eliminate one layer of risk for the lender, and rates often improve slightly. At 20% down, PMI is gone entirely and you are working with the most straightforward version of a conventional mortgage. The table below shows what each tier looks like on a $600,000 Arizona purchase.

Down Payment %	Down Payment ($600K)	Loan Amount	PMI Required?	Program
3%	$18,000	$582,000	Yes	HomeReady / Home Possible
5%	$30,000	$570,000	Yes	Standard Conventional
10%	$60,000	$540,000	Yes (lower rate)	Standard Conventional
20%	$120,000	$480,000	No	Standard Conventional

The decision between these tiers is not just arithmetic. It involves your cash reserves after closing, your monthly budget, and how quickly home values might appreciate in your area. In Scottsdale neighborhoods with strong appreciation history, a 5% down buyer who builds equity quickly might reach 20% LTV faster than the schedule shows on paper, which opens the door to canceling PMI ahead of the scheduled date. That is worth modeling when you sit down to plan. The minimum down payment for a Fannie Mae HomeReady conventional loan is 3%.

What Credit Score Do I Need for a Conventional Loan?

The floor is 620. That is the minimum credit score that most conventional lenders, including those following Fannie Mae and Freddie Mac guidelines, will accept. Below 620 and you are generally looking at other options, either FHA or a credit repair period before reapplying. But the floor is not the goal. A 620 score gets you in the door; it does not get you the rate you want.

The pricing grid for conventional loans is called Loan Level Price Adjustments (LLPAs). Fannie Mae publishes this grid and it is the reason two buyers with different credit scores, same down payment, same loan size, will receive different interest rates. The adjustments are cumulative. A buyer at 660 pays more in pricing adjustments than a buyer at 700. A buyer at 700 pays more than one at 740. Once you cross 740, you are in the top pricing tier and adjustments either disappear or shrink to their minimum. For a 30-year loan on a $600,000 purchase, the rate difference between a 650 score and a 740 score can be 0.5% to 0.75%, which translates to roughly $150 to $225 per month in payment and tens of thousands of dollars over the life of the loan.

If your score is in the 600s and you are seriously considering buying in the Scottsdale, Arizona area in the next six to twelve months, credit optimization is worth the conversation. In some cases, paying down a revolving balance or disputing an error can move a score 20 to 40 points in 60 days. That kind of move, timed correctly, can drop your rate before closing. It is not guaranteed, but it is worth modeling with your lender before you lock. Most lenders require a minimum credit score of 620 to qualify for a standard conventional loan, but the sweet spot for best pricing is 740 or above.

How PMI Works on a Conventional Loan (and When It Ends)

Private mortgage insurance, or PMI, is the cost you pay when you put less than 20% down on a conventional loan. It protects the lender against default risk, not you. It shows up as a monthly line item on your payment, typically ranging from 0.2% to 1.5% of the loan amount annually, depending on your credit score, loan-to-value ratio, and lender. On a $540,000 loan at 0.7% annually, that is roughly $315 per month. It is real money, but it is also temporary in a way that FHA mortgage insurance is not.

The Homeowners Protection Act of 1998 governs exactly when and how PMI must end on conventional loans. There are three triggers to know. First, automatic cancellation: your lender is required to cancel PMI on the date your loan is scheduled to reach 78% of the original property value, based on your amortization schedule alone. This happens without you doing anything, but it can take years on a 30-year loan if you only make minimum payments. Second, borrower-requested cancellation: once your actual loan balance reaches 80% of the original purchase price, you can submit a written request to cancel PMI. Your lender must honor it if you have a good payment history and, in some cases, a current appraisal confirming value has not dropped. Third, appreciation-based cancellation: if the property has appreciated significantly, you may be able to request cancellation based on a new appraisal showing you have 20% equity in the current value rather than the original purchase price. Lenders are not required to honor this path, but many will consider it after two years of on-time payments.

PMI’s built-in expiration date is one of the biggest structural advantages of conventional over FHA for Arizona buyers. On an FHA loan originated with less than 10% down, the mortgage insurance premium runs for the entire loan term. It never automatically cancels. You would have to refinance out of FHA into a conventional loan once you have enough equity to avoid PMI. On a conventional loan, the insurance is genuinely temporary. Under the Homeowners Protection Act of 1998, PMI on a conventional loan must be automatically canceled when the loan-to-value ratio reaches 78% of the original purchase price based on the amortization schedule.

How Is a Conventional Loan Different from FHA in Arizona?

The conventional-versus-FHA question comes up in almost every Arizona buyer conversation, and the right answer is not “FHA is for people with bad credit.” That framing is outdated and it leads buyers to make the wrong call. Let me walk through the real differences.

FHA loans are insured by the Federal Housing Administration. Because the government backs the lender against default, FHA loans accept lower credit scores (as low as 580 with 3.5% down, or 500 with 10% down) and allow higher debt-to-income ratios than most conventional programs. They also have looser appraisal standards in some cases. For buyers with credit below 620, FHA is often the only conforming option on the table. But the insurance structure is where FHA becomes expensive over time.

FHA loans carry two layers of mortgage insurance. An upfront mortgage insurance premium (UFMIP) of 1.75% of the loan amount is added to the loan at closing. On a $500,000 purchase with 3.5% down, that is an $8,444 upfront charge rolled into your loan balance, meaning you pay interest on it for the life of the loan. Then there is an annual MIP of 0.55% (for most 30-year FHA loans at current rates), charged monthly for the life of the loan if you put less than 10% down. On a $482,500 loan (after 3.5% down on $500K), that is roughly $221 per month in MIP that never goes away unless you refinance.

On a conventional loan, there is no upfront mortgage insurance charge. PMI is only the monthly component, and it cancels at 80% LTV by request or 78% LTV automatically under the Homeowners Protection Act of 1998. For a buyer with a credit score of 680 or higher, conventional mortgage insurance is almost always cheaper than FHA MIP, even starting from the same down payment. The breakeven point shifts as credit scores rise. At 720+, conventional is typically superior by a meaningful margin. At 640, the gap narrows and depends on the specific PMI pricing your lender can source. The biggest structural difference between conventional and FHA is mortgage insurance: FHA MIP runs for the life of the loan at under 10% down, while conventional PMI cancels at 80% loan-to-value.

Arizona Price Band Comparison: Conventional vs. FHA

Numbers cut through the noise faster than explanations. The table below models three Arizona price points that are common in the Scottsdale and greater Phoenix market: $500,000, $750,000, and $850,000. For each we compare conventional at 5% down against FHA at 3.5% down, showing down payment required, estimated monthly PMI or MIP, and the key difference. All figures are illustrative estimates based on 2026 program guidelines. Your actual numbers will depend on your credit score, lender, and current rates.

Home Price	Loan Type	Min Down	Loan Amount	Est. Monthly MI	MI Duration
$500,000	Conventional (5%)	$25,000	$475,000	~$250	Cancels at 80% LTV
$500,000	FHA (3.5%)	$17,500	$482,500 + $8,444 UFMIP	~$221	Life of loan (if <10% down)
$750,000	Conventional (5%)	$37,500	$712,500	~$375	Cancels at 80% LTV
$750,000	FHA (3.5%)	$26,250	$723,750 + $12,666 UFMIP	~$332	Life of loan (if <10% down)
$850,000	Conventional (5%)	$42,500	$807,500	~$425	Cancels at 80% LTV
$850,000	FHA (3.5%)	$29,750	$820,250 + $14,354 UFMIP	~$376	Life of loan (if <10% down)

The table tells a clear story. For buyers at or above $600,000, FHA is often not just more expensive in mortgage insurance. It may not even be available at typical down payment levels in Maricopa County. The conventional loan is the primary tool at Arizona’s most active price points, and understanding it thoroughly is not optional. The FHA loan limit for Maricopa County in 2026 is $546,250 for a single-family home, well below the median Scottsdale purchase price.
