How long does a mortgage application take UK?

Typically 2-6 weeks from application to offer. Agreement in Principle takes hours to days. Full application processing is 2-4 weeks. Complex cases take longer. Delays often come from valuations, legal work, or missing documents.

What do I need to apply for a mortgage first-time buyer?

ID (passport/driving licence), proof of address, 3 months' payslips, 3 months' bank statements, proof of deposit, P60, and details of outgoings/debts. Self-employed need 2-3 years' accounts. The more organised, the faster the process.

How much deposit do I need for first mortgage?

Minimum 5% for most lenders, but 10% gets better rates, and 15-20% gets the best rates. On £250,000, that's £12,500 (5%), £25,000 (10%), or £50,000 (20%). Larger deposits mean more options and lower monthly payments.

Can I get a mortgage with bad credit UK?

Possible but harder. Options include specialist lenders, larger deposits, guarantor mortgages, or improving credit first. Recent issues are worse than old ones. Check your credit file first and consider a mortgage broker who knows specialist lenders.
