CONSTRUCTION LOANS

A deep dive into Arizona construction-to-permanent financing — how it works, what it costs, and how to structure it right the first time.

CONSTRUCTION LENDING IN THE SONORAN DESERT

Arizona's construction market has unique characteristics that affect how loans are structured. The state permitted over 31,000 new homes in 2024 — a 37% increase from prior years — making it one of the most active construction markets in the country. That volume creates both opportunity and competition for lots, builders, and financing.

The Sonoran Desert climate adds complexity that lenders in other states don't deal with. Monsoon season (July through September) can delay exterior work. Summer heat affects concrete curing schedules. These factors influence realistic build timelines, which in turn affect how we structure your draw schedule and construction period.

Arizona also has county-specific permitting timelines that vary significantly. Maricopa County has streamlined its residential permitting process, while Pima County (Tucson) and Coconino County (Flagstaff) can run longer. We factor these into your pre-approval and timeline planning.

Land Financing

Lot Purchase Loan

Secure your lot before you're ready to build. Arizona's best lots move quickly — especially in Scottsdale, Cave Creek, and the East Valley. A lot loan lets you lock in your land now and transition to construction financing when your plans and builder are ready.

  • Lock in your lot before plans are finalized
  • Up to 10-acre properties, improved or unimproved
  • 15-year fixed rate with up to 20-year amortization
  • Designed for future primary or secondary residence builds
  • Transitions cleanly into construction-to-permanent financing

Rate Protection

Rate Float-Down Option

Lock your rate at closing and retain the option to float down if market rates drop during your build period. Most construction loans lock you in with no relief if rates fall. Our float-down option gives you protection in both directions — rate certainty going in, and flexibility if the market moves in your favor.

  • Rate locked at closing before construction begins
  • Float-down available if market rates drop during build
  • Exercised at conversion — no second closing required
  • Reduces rate risk on long build timelines
  • Ask your loan officer for current float-down terms

Loan Modification & Conversion

When your home is complete, the construction loan converts to permanent financing without a second closing. No second appraisal, no second loan approval. The modification process is handled by our construction team, who reaches out to the borrower approximately one month before the conversion date.

  • Single-close means one approval, one set of closing costs
  • Loan modifies automatically at construction completion
  • Certificate of Occupancy triggers the conversion process
  • Float-down option available at conversion if rates have dropped
  • Construction Specialist coordinates the process with borrower and builder

CONSTRUCTION LOAN FAQ

What's the difference between a construction loan and a construction-to-permanent loan?

A standalone construction loan covers only the build period and must be paid off or refinanced when construction ends. A construction-to-permanent loan (C2P) converts automatically to a mortgage at completion. The C2P structure saves you a second closing, second set of fees, and the rate risk of refinancing into an unknown market.

How does the draw schedule work in Arizona?

Draws are disbursements tied to completed construction milestones. In Arizona, a typical draw schedule includes: lot acquisition (if applicable), foundation, framing, rough mechanical/electrical/plumbing, insulation and drywall, exterior finish, interior finish, and final completion. Each draw requires an inspection before funds are released.

Can I lock my interest rate before construction starts?

Yes. With our single-close construction-to-permanent program, you lock your rate at closing — before the first shovel hits the ground. We also offer a float-down option: if rates drop during your build period, you may qualify for a lower rate at conversion. Ask your loan officer for current float-down terms.

What credit score do I need for an Arizona construction loan?

For conventional construction loans, we typically look for a 680+ credit score. FHA and VA construction programs may allow down to 620. A higher score generally unlocks better rates and higher LTV options.

How long does the approval process take for a construction loan?

Construction loan approvals take longer than standard mortgages because we're underwriting both the borrower and the project. Plan for 30 to 45 days from application to closing. This includes reviewing your builder's credentials, the construction contract, the project budget, and the appraisal based on completed plans.

Does my builder need to be pre-approved?

Yes. We require your general contractor to be licensed with the Arizona Registrar of Contractors (ROC), carry adequate liability insurance, and provide a detailed construction contract and budget. We review builder credentials as part of the loan approval process. If you're acting as your own GC, see our Owner-Builder program.

What happens if my build goes over budget?

Cost overruns are one of the most common challenges in construction lending. We build a contingency reserve into the budget during underwriting — typically 5 to 10% of total project cost. If overruns exceed the reserve, you'll need to bring additional funds to close the gap. This is why accurate budgeting upfront matters.

Can I use a construction loan to build on land I already own?

Yes. If you own your lot free and clear, the equity in the land can often be used toward your down payment requirement. If you have an existing lot loan, we can structure the construction loan to pay off the lot loan at closing and roll everything into a single construction-to-permanent loan.
