TSMC Arizona Salary Data — What the DOL Filings Show
TSMC Arizona Corporation files Labor Condition Applications (LCAs) with the U.S. Department of Labor before sponsoring H-1B employees. These filings are public record and represent the closest approximation to actual base salaries — they are the minimum wage TSMC must pay for each role, and in practice tend to closely match actual offers.

Affordability Tiers by TSMC Role
Standard mortgage underwriting uses a 28% front-end ratio (housing costs to gross income) and a 43% back-end ratio (all debt to gross income). At current rates (mid-2026 30-year fixed approximately 6.5–7.0%), here is what each salary tier qualifies for with a 10–20% down payment and no significant other debt.
With 10–20% down, qualifies for townhomes and condos in Norterra (85085), entry single-family in the North Gateway new construction corridor, and Anthem Parkside resale. Nova North Valley apartments ($1,179/mo+) or Norterra rentals ($1,560–$2,040/mo) are the rental bridge while building credit history or awaiting green card status.
The median TSMC Arizona salary range. Qualifies for single-family homes in Norterra, Sonoran Foothills, Stetson Hills, and lower Anthem Parkside with 20% down. At the 75th percentile ($112K), entry Cave Creek Tatum Ranch is in range. HOA dues must be factored — typically $100–$385/month in master-planned communities, which reduces borrowing capacity.
Senior engineers and technical leads. Qualifies for single-family homes across the full Norterra–Anthem corridor, Desert Hills acreage (1–2 acres, custom builds, no HOA), upper Tatum Ranch Cave Creek, and Dove Valley Ranch Cave Creek. At $160K, entry Anthem Country Club gated homes and lower Carefree condos ($500K–$700K range) are reachable with 20% down.
Senior managers, principal engineers, directors. Qualifies for Anthem Country Club (gated golf, $750K–$2M), Desert Hills premium acreage ($1M–$1.8M), Cave Creek foothills custom homes, The Boulders Carefree casitas and lower mid-range homes ($825K–$1.5M). Carefree's no-local-real-estate-tax structure makes it more attainable than the median price suggests at this income level.
Financing on an H-1B or TN Visa
Most TSMC employees on H-1B visas can obtain conventional mortgage financing in the U.S. — but the requirements are specific and vary by lender. Dominion's in-house lending through Foothills Mortgage Group LLC (NMLS 1904177) has experience with non-citizen and visa-holder transactions. Key points:
- H-1B holders are eligible for conventional (Fannie Mae/Freddie Mac), FHA, and many portfolio loan products. A valid H-1B visa with at least 12 months remaining, two years of U.S. employment history (or a signed employment contract for new hires), and a U.S. credit profile are the standard requirements.
- No SSN yet? An Individual Taxpayer Identification Number (ITIN) can be used for initial banking and credit establishment. SSN typically arrives 2–4 weeks after arrival. Some lenders will pre-approve with an ITIN pending SSN issuance.
- Credit history is the most common obstacle for newly arrived employees. U.S. lenders cannot use Taiwan credit history. Start building U.S. credit immediately upon arrival: secured credit card, auto loan, or credit-builder loan. 12 months of U.S. credit history significantly expands your options.
- Down payment: Foreign funds wired from Taiwan for down payment must be properly documented — a gift letter is not sufficient for wired international funds. Your lender will need 60 days of account statements showing the funds were in a U.S. account, or full source-of-funds documentation for recent wire transfers.
