Thinking about buying a brand-new home in Arizona?

Before you walk into a model home in San Tan Valley, Queen Creek, Gilbert, Chandler, Apache Junction, Gold Canyon, or Florence, there are two people you should contact first:

Your own Realtor and your own lender.

New construction can be an exciting path to homeownership. You may get to choose finishes, select an available floor plan, and move into a home with modern features and energy-efficient designs.

But the process is not always as simple as touring a model home and signing a contract. Builder registration rules, preferred-lender incentives, upgrades, lot premiums, and closing costs can all affect your final price and monthly payment.

The good news is that you do not have to navigate those decisions alone. With the right guidance before your first visit, you can move forward with greater confidence.

Why should you call your Realtor before visiting a model home?

Many Arizona builders require your Realtor to accompany you or register you during your first visit to the community.

If you visit the model home alone, the builder may not allow your Realtor to represent you later. This can happen even if you had not yet decided whether to buy or had only stopped by to look around.

That matters because the salesperson at the model home works for the builder.

Your Realtor is there to look out for you.

Your own Realtor can help you:

• Understand the builder’s contract and deadlines

• Compare communities and floor plans

• Review lot premiums and upgrade costs

• Evaluate the builder’s incentives

• Coordinate inspections

• Understand warranty coverage

• Identify questions you may not think to ask

• Help protect your interests throughout the transaction

The builder’s sales representative can be helpful and knowledgeable. However, their responsibility is to the builder and the builder’s sales process. Having your own Realtor gives you a dedicated advocate who can help you evaluate the complete purchase from your perspective.

Call your Realtor before visiting the model home: not afterward.

Why should you contact your lender before choosing a builder?

The same caution applies to the builder’s preferred lender.

A builder may advertise an attractive interest rate, closing-cost credit, or upgrade package. Those offers may be valuable, but they are often tied to using the builder’s preferred lender.

Before you become attached to a particular floor plan or community, it helps to understand:

• How much home you may comfortably afford

• Which loan programs may fit your needs

• How much cash you may need at closing

• What your estimated monthly payment could be

• Whether the builder’s financing offer is truly competitive

• How the incentives affect the purchase price and total loan cost

A personalized pre-approval gives you a helpful starting point. You can begin your online pre-approval here, or contact San Tan Mortgage if you would like to talk through your plans first.

A pre-approval is not a commitment to purchase a home. It is a practical way to understand your options before you begin comparing new-construction communities.

Is that builder incentive really free?

Builders often advertise:

• Special interest rates

• Thousands toward closing costs

• Flex cash

• Free appliances

• Discounted upgrades

• Reduced lot premiums

• Design-center credits

• Landscaping packages

These incentives may provide real savings, but they are often connected to the builder’s preferred lender or title company.

A large credit or below-market interest rate does not automatically mean you are getting the best overall deal. The offer needs to be compared with the full purchase price, loan terms, fees, monthly payment, and long-term cost.

I recently worked on a transaction where the buyer could purchase the same home for a lower price by using an outside lender. The higher purchase price with the builder’s lender was helping cover the cost of the advertised interest-rate buydown.

In other words, the buyer was not necessarily receiving a “free” lower rate. They were paying more for the home to help create it.

That does not mean a builder’s preferred lender is always the wrong choice. In some cases, the incentive package may provide meaningful savings. The important thing is to compare the numbers side by side before you commit.

A temporary rate buydown may also make the initial payment look especially attractive while the payment increases later. A permanent rate reduction may have a different cost structure. Closing-cost credits may be useful, but they can be limited by loan guidelines and the amount of your actual eligible costs.

The best offer is the one that fits your complete financial picture: not just the one with the biggest headline.

What should you ask before committing?

Before signing a purchase contract or choosing a lender, ask clear questions about the builder’s offer.

ask these questions

• What is the price of the home if I pay cash?

• Is the price different if I use an outside lender?

• Do I have to use the builder’s lender to receive the incentive?

• Is the advertised interest rate temporary or permanent?

• Are discount points included in that rate?

• Can I use the incentive toward closing costs instead?

• What is the final price after upgrades and incentives?

• Are there lot premiums for this homesite?

• What happens if construction is delayed?

• When will my interest rate need to be locked?

• Are there HOA, CFD, SID, or other community-related fees?

• What inspections are allowed during construction and before closing?

• What is covered under the builder’s warranty?

These questions are especially important when comparing new construction in growing East Valley areas. A base price may look appealing, but the final price can change after you select a homesite, add structural options, choose design upgrades, and include required or preferred features.

Your Realtor and lender can help you understand how those choices affect your total cost.

How can you compare the complete picture?

Make sure the builder’s lender and your own lender are quoting the same purchase price, down payment, loan program, and closing date.

Then compare:

• Purchase price

• Interest rate and APR

• Monthly payment

• Discount points and lender fees

• Mortgage insurance

• Property taxes and homeowners insurance

• HOA or community-related costs

• Cash needed at closing

• Builder credits

• Value of upgrades or other incentives

• Total cost of the loan

If the builder is offering a temporary buydown, compare the payment during each stage: not just the first year.

For example, ask to see:

• The initial monthly payment

• The payment after the first adjustment

• The expected payment once the temporary incentive ends

• The total amount paid over the period you expect to own the home

Also compare the same loan type and assumptions. A conventional loan quote should not be compared casually with an FHA loan quote without reviewing the different down payment, mortgage insurance, and qualification requirements.

The builder’s lender may still offer the better option. You should simply know that before you commit.

What is the best way to approach a new-construction purchase?

A simple process can help you make more informed decisions.

1. Choose your Realtor first

Find a Realtor who understands Arizona new construction and is familiar with communities in areas such as San Tan Valley, Queen Creek, Gilbert, Chandler, Apache Junction, Gold Canyon, and Florence.

2. Contact your lender early

Get a personalized pre-approval and establish a baseline for your expected payment and cash-to-close.

3. Visit the model home with your Realtor

Make sure your Realtor is present and registered with the builder during your first visit.

4. Request the builder’s complete incentive offer

Ask for the rate, credits, points, fees, loan assumptions, and expiration dates in writing.

5. Compare an outside lender

An outside lender can provide another option and help you understand whether the builder’s preferred financing is competitive.

6. Review the final numbers

Do not compare only the advertised interest rate. Compare the purchase price, payment, cash needed, fees, and total loan cost.

7. Ask questions before signing

It is always better to ask a question early than discover an important detail after you have committed.
