The moment a buyer applies for new credit — a furniture store card, a car loan, a buy-now-pay-later plan — two things happen simultaneously: the credit inquiry causes a small score drop, and the potential new monthly payment raises the debt-to-income ratio. If DTI goes above the program limit, the loan is denied. No exceptions, no explanations accepted.

Buying a car, financing furniture, or making any large cash purchase creates two simultaneous problems. If financed, it raises your DTI. If purchased with cash, it reduces the verified bank balance the underwriter approved. The underwriter approved a specific balance. If that balance has dropped materially, the underwriter will ask why — and may adjust the approval.

Lenders require two years of employment history and verify employment at pre-approval and again right before closing. A job change — even a lateral move at higher pay — resets the income verification clock. Changing from salaried to self-employed during underwriting will almost certainly delay or deny the loan, since lenders typically require 2 years of self-employment income history before they can count it.

Lenders must document the source of all significant deposits. An undocumented transfer — even a gift from a family member, even a reimbursement from a friend — triggers an underwriter request for a Letter of Explanation and supporting documentation. If the source cannot be verified, the funds cannot be used.

A pre-qualification letter is a lender’s opinion based on what you told them — none of it verified. A pre-approval requires documentation review by an underwriter. In the current Phoenix market, listing agents know the difference. An offer with a pre-qualification letter signals the buyer has not done the real work. A full underwritten pre-approval signals a buyer who can close.

Rate differences of 0.25% to 0.50% are common between lenders for the same borrower profile. On a $400,000 loan, 0.50% over 30 years is approximately $42,000 in total interest. Buyers who go with the first lender they talk to routinely leave real money on the table. Getting quotes from two or three lenders takes a few hours. The credit inquiry impact is minimal if done within a 14- to 45-day window.

The down payment is the most visible upfront cost, but not the only one. On a $400,000 Phoenix home, buyers should also budget for: closing costs ($8,000–$12,000), prepaid homeowner’s insurance (12 months at closing), property tax escrow funding (2–3 months), HOA transfer fees ($200–$400), HOA capital improvement or community enhancement fees (up to 0.5% of purchase price in master-planned communities), appraisal ($400–$550), and inspection ($400–$1,000 all-in with add-ons).

In Phoenix, lot orientation determines afternoon temperatures in outdoor living areas. A home with a south- or west-facing rear yard is in direct sun from midday through sunset — the hottest hours of the day, every day from April through October. A home with a north- or east-facing rear yard is shaded during those same hours. The difference in yard usability, pool cooling costs, and exterior surface temperature between these orientations is not subtle. Out-of-state buyers almost universally miss this on their first purchase.

Approximately 36% of Phoenix-area homes have a pool, and pool equipment is not included in the standard home inspection — it is an add-on costing $75–$150. Buyers who skip it inherit the seller’s deferred maintenance: aging pumps (8–12 year life), failing heaters (7–12 year life), degraded plaster (10–15 year life), deck cracks. Pool resurfacing: $5,000–$12,000. Heater replacement: $2,000–$4,500 installed.

The Wood Destroying Insect Inspection Report is a separate inspection from the standard home inspection, conducted by a licensed pest control company. It is required for VA and FHA financing and strongly recommended for every Phoenix resale. Subterranean termites are endemic to Arizona — they live in the soil year-round and can be present in a home with no visible surface damage. Inspection cost: $50–$75. Structural damage repair costs: hundreds to thousands of dollars.

A sewer scope runs a camera through the main sewer lateral from the home to the city connection. For homes over 15–20 years old, root intrusion from mature trees is common. Clay pipe used in homes built before the 1980s is prone to cracking and offset joints. Full sewer line replacement: $10,000–$20,000. Spot repair: $3,000–$6,000.

Arizona ranks third nationally in HOA density. In the West Valley, the overwhelming majority of homes in Goodyear, Buckeye, Surprise, Peoria, and Anthem are in HOA communities. Under Arizona law, sellers must provide HOA disclosure documents within 10 days of contract acceptance. Reference: Arizona Association of Realtors Buyer’s Advisory (aaronline.com).

The documents that matter: the CC&Rs (what you can and cannot do), the financial statements (reserve fund balance — an underfunded HOA is a special assessment waiting to happen), the meeting minutes (recent disputes, deferred maintenance, pending litigation), and the current dues and any pending increases.

HOA transfer fee: $200–$400, to change the account from seller to buyer. HOA disclosure/resale fee: Up to $400 under Arizona statute — often negotiated to be paid by the seller but sometimes shifted to the buyer. Capital improvement or community enhancement fee: Common in master-planned communities like Vistancia, Verrado, Eastmark, and Estrella Mountain Ranch. Typically 0.25%–0.5% of the purchase price, paid by the buyer at closing. On a $450,000 home, 0.5% is $2,250 — payable at the closing table.

In a market where 59.6% of Phoenix closings occur below list price and sellers are receiving an average of 97.7% of final list price, the list price is the seller’s opening position — not the market’s verdict. Buyers who anchor their offer to the list price and negotiate down from there are using the seller’s math. The correct anchor is comparable closed sales in the same submarket, adjusted for concessions.

During the 2021–2022 frenzy, buyers routinely waived inspection rights to compete. In the current Phoenix market — 94 average DOM, 5.17 months supply — waiving inspection on a resale home trades away your strongest mid-transaction protection for a competitive advantage you no longer need. The inspection period is the only time a buyer can cancel the contract for virtually any reason and recover the earnest money deposit in full.

The SPDS (pronounced “speeds”) is a form the seller completes listing everything they know about the property’s condition, history, and defects. Under the standard AAR contract, the seller must deliver the SPDS within 3 days of contract acceptance. It covers prior roof leaks, flooding events, permitted and unpermitted work, insurance claims, pest activity, and neighborhood nuisances. Buyers who sign it without reading it miss information the seller was legally obligated to share.
