HOA and assessments
All residential owners belong to the Union Park at Norterra Community Association, per the community site. On November 4, 2026, the official agent resources page listed a master association assessment of $190 per month, billed quarterly. It listed an added assessment for one builder collection. It named CCMC as the HOA contact.
Amounts change. For a resale home, Arizona law (A.R.S. §33-1806) requires the seller to give the buyer key association documents, including the current assessment. For any home, check the tax bill and title commitment for CFD or SID assessments on that parcel.
Buying a New Build in Union Park
The builder's on-site sales agent represents the builder. Ryan represents you.
The official agent page says builders request that agents accompany clients on their first visit to Union Park builder models. Register Ryan before your first model-home visit. Rules vary by builder, so check before you go. If you already toured, call Ryan anyway and he will tell you where you stand.
Here is what Ryan does for a new-build buyer:
- Builder incentives. He gets the offer in writing and checks what it is tied to, such as using the builder's lender or closing by a set date. On November 4, 2026, the official agent page showed quick move-in homes and a limited incentive from one builder. Incentives change often.
- Rate buydowns. He compares a builder-paid rate buydown with a price reduction or closing-cost credit. Get an outside lender quote too, so you can compare the full cost.
- Contract review. Builder contracts are written by the builder. Ryan walks through the deposit, timelines, change orders, warranty, HOA terms, and any CFD or SID assessment before you sign.
- Comparing builders. He lines up floor plans, lots, included features, and incentives side by side, in Union Park and other North Phoenix communities.
Ryan's help is at no cost to you. The builder typically pays Ryan's commission, confirmed in writing before you sign.
Next step: Tell Ryan what you want in a home with the New Home Finder, or book a call. You can also call or text (480) 227-9143. Looking at the wider area? See the Norterra guide.
Arizona Rules That Apply Here
These are statewide. Your contract and your title company control the details.
| Item | What it means | Confirm with |
|---|---|---|
| BINSR | Under the standard AAR resale contract, the buyer has a 10-day inspection period by default and the seller has 5 days to respond to the Buyer's Inspection Notice. Builder contracts usually set their own inspection terms. | Your purchase contract |
| SPDS | The AAR resale contract calls for the seller to give a Seller's Property Disclosure Statement. A builder sale usually uses the builder's own disclosures instead. | Your contract and agent |
| HOA disclosure | For a resale in a planned community, A.R.S. §33-1806 requires the seller to provide association documents and assessment details to the buyer. | The association and title company |
| CFD / SID | Special districts formed under A.R.S. Title 48 can add an assessment to a property tax bill. Whether one applies depends on the parcel. | Tax bill and title commitment |
| 2026 conforming loan limit | FHFA set the 2026 baseline one-unit limit at $832,750. It is a national baseline; whether a specific loan is conforming depends on the loan and the lender. | Your lender |
Buying or selling with current facts
Price, tax or assessment amounts, HOA rules, permits, construction features, rental restrictions, and school assignment are property-specific and can change. Review current listing and title materials, then confirm relevant details with the association, government agencies, school district, and appropriate professionals before making a decision.
Buying a new construction home
If you are considering a new build at Union Park or elsewhere in North Phoenix, bring Ryan in before your first model home tour. The on site sales agent represents the builder. Ryan represents the buyer and can help compare builder incentives, rate buydown options, contract terms, lot choices, warranty documents, and monthly ownership costs for the specific home. Builder registration rules vary, so confirm buyer representation before the first visit.
