Model homes are designed to make you fall in love.
The lighting is perfect. The finishes are curated by professional designers. The furniture makes every room feel exactly the right size. There is fresh coffee brewing somewhere. And the sales agent is warm, friendly, and very, very helpful.
What that agent will not do is tell you everything you need to know before you sign a builder contract.
That is my job.
I work with buyers purchasing new construction homes across the East Valley every week. And there are things that consistently surprise buyers — sometimes pleasantly, sometimes expensively — when they learn them after the fact rather than before.
Here is what nobody tells you.
The Builder’s Sales Agent Works for the Builder — Not for You
This is the most important thing I will tell you in this entire blog post.
The friendly sales agent you meet at the model home is a professional whose job is to sell you a home at the best possible price for the builder. They are not your advocate. They are not working to get you the best deal. They work for the builder — and the builder pays their commission.
When you bring your own real estate agent — someone like me — to the builder’s model home, that agent represents you. They review the contract for buyer-unfavorable clauses. They negotiate incentives, upgrades, and lot premiums on your behalf. They know which things builders will negotiate on and which ones they will not. And in almost all cases, the builder pays your agent’s commission — meaning you get professional representation at no additional cost to you.
Buyers who sign builder contracts without their own representation regularly report afterward that they missed better incentive packages, paid lot premiums they could have negotiated down, or signed escalation clauses they did not fully understand.
Bring your own agent. It costs you nothing and protects you substantially.
The Model Home Is Not What Your Home Will Look Like
The model home you fell in love with is finished to a level that is typically $75,000-$150,000 above the base price of the same floor plan.
Those gorgeous quartz countertops — upgrade.
The hardwood-look plank flooring throughout — upgrade.
The extended covered patio — upgrade.
The gourmet kitchen package with built-in appliances — upgrade.
The master bath spa shower with frameless glass — upgrade.
The outdoor kitchen and built-in fire pit in the backyard — not included. At all.
Standard finishes in new construction are — standard. Builders call them designer selections. They are functional. They are basic. They are not what you saw in the model.
Before you fall in love with a floor plan, ask the sales agent to show you exactly what the standard selections are and to provide a written quote for every upgrade you want to add. Then add those costs to the base price and see if the total still makes financial sense.
The Backyard Is Your Responsibility — Completely
New construction homes in Arizona come with a backyard that is essentially a dirt lot.
No landscaping. No grass (which in Arizona is artificial turf if you want it). No trees. No patio furniture. No shade structures. Nothing.
Budget between $8,000 and $30,000+ for backyard development depending on what you want. A basic concrete pad and decomposed granite runs $8,000-$12,000. Adding turf, trees, a pergola or ramada, and outdoor furniture is $15,000-$25,000. A pool — which many East Valley buyers want — adds $50,000-$80,000 or more.
This is not a hidden cost — it is disclosed in the contract. But it consistently surprises buyers who have budgeted for the purchase price but not the move-in ready reality.
Also budget for: window coverings (blinds and curtains throughout the house), ceiling fans, light fixtures that go beyond builder-standard, garage shelving and storage, and landscaping in the front yard if the builder has not included it.
Plan on $15,000-$35,000 in move-in costs beyond the purchase price for a typical new construction home in the East Valley.
The Builder’s Preferred Lender — Understand the Trade-Off
Builders almost always offer incentives — closing cost credits, additional upgrades, rate buydowns — if you use their preferred lender.
These incentives are often real and substantial — $10,000-$20,000 in closing cost credits is common.
But the preferred lender may not offer the best overall rate or loan terms. The incentive is designed to capture your business for the builder’s financial partner — who then shares revenue back with the builder.
What you should do: get pre-approved with both the builder’s preferred lender AND an independent lender. Compare the total loan cost — rate, fees, and terms — with the incentive included and without. In some cases the preferred lender incentive more than compensates for a slightly higher rate. In other cases the incentive does not cover the cost difference over the life of the loan.
Your buyer’s agent can help you evaluate this comparison. It is one of the most impactful financial decisions in the entire transaction and deserves careful analysis.
Builder Contract Clauses That Buyers Miss
Builder contracts are not the standard Arizona Residential Purchase Contract that most buyers are familiar with. They are contracts written by the builder’s attorneys to protect the builder. Some common clauses buyers are surprised by include:
Escalation Clauses
Some builder contracts allow the builder to increase the price of the home under certain conditions. Read this section carefully with your agent and ask the builder to explain any price protection provisions.
Construction Timeline Flexibility
Builder contracts typically allow significant timeline flexibility. Your projected move-in date is an estimate — not a guarantee. Delays of 30-90 days are not unusual. If you have a hard move-in deadline driven by a lease end date or school year, confirm what the contract actually guarantees and what the builder’s track record is for delivering on schedule.
Change Order Restrictions
Once you have signed your design selections and options, changes are typically expensive and sometimes impossible. Be certain of your upgrade choices before signing.
Warranty Coverage Details
Builder warranties are one of the most compelling advantages of new construction. But read exactly what is covered and for how long. Standard new construction warranties typically include 1 year on workmanship and materials, 2 years on mechanical systems (plumbing, electrical, HVAC), and 10 years on structural defects. Understand what is excluded and what the claims process requires.
New Construction Appraisals Can Be Tricky
Your lender will require an appraisal of your new construction home before closing. In a fast-moving new construction market, appraisals sometimes come in below the purchase price — particularly if comparable sold homes in the community are earlier-phase sales at lower prices.
If the appraisal comes in below your purchase price, the builder may not automatically reduce the price. Understand your appraisal contingency rights in your specific contract before you sign.
Your New Home Will Settle — Plan for It
New construction homes settle in the first 1-3 years as the structure adjusts to the desert environment. This typically manifests as hairline cracks in drywall, slightly sticking doors, or minor grout cracking in tile.
These are normal. They are not structural defects. Do your warranty walk-through at the 11-month mark — just before your 1-year workmanship warranty expires — and document everything that needs attention. This is your opportunity to have the builder address cosmetic settling before the warranty window closes.
The Bottom Line on New Construction in 2026
New construction in the East Valley right now is genuinely compelling — builder incentives, rate buydowns, warranty protection, modern design. I would not tell you otherwise.
But go in with full information. Bring your own agent. Read the contract carefully. Budget for the extras. Understand who the sales team represents. And enjoy the model home for what it is — an aspiration — while making decisions based on the reality of your specific purchase.
I help East Valley buyers navigate new construction purchases every week. Let me help you get the best deal possible.
