Scottish Affordability Fundamentals
Affordability in Scotland blends UK-wide FCA rules with devolved perks: Lenders cap payments at 4.5-5x income (some 6x LTIs), stress test at contract rate +3% or 8.5% minimum, plus manual checks on outgoings. For £40k salary (£3,333/mo gross), max £1,500 payments yields £250k mortgage over 30yrs at 4.75%. Edinburgh’s £320k averages demand 10%+ deposits; rural Highlands stretch further.
Journalistic note: 2025 LBTT holiday extension aided 12k transactions; 2026 election looms policy shifts.
Deposit rules: 5% min uninsured (higher risk), 10-25% unlocks sub-4% rates. Shared equity schemes fill gaps.
