Zeynep Turan – Consumer Financing & Mortgage Credit Strategist: "The hefty tax bills of these corporations may push banks to tighten credit policies further. Consumers should look beyond traditional loans to avoid higher filing fees and interest rates. Institutions offering low‑interest mortgages and flexible repayment terms are likely to gain traction in this environment."
