1. Establish affordability and the purchase budget
The purchase price alone does not establish affordability. Begin with a household budget using reliable income and realistic expenses. Include utilities, insurance, maintenance and any property management charges as well as the loan payment.
Test the payment against reduced income or higher refinancing rates. Keep the price, transaction costs, planned work and liquid reserve as separate budget lines. A subsidised loan remains a repayable liability.
2. Prepare personal and property documents
Request a document list tailored to your case. It may include identification, income evidence, liabilities, savings and property documents. The property information required for a new build or apartment differs from other purchases.
Keep information consistent and identify changes. Submit confidential records through the agreed secure channel, not a general distribution list. Record missing evidence together with a clear owner and next action.
3. Compare proposals on equivalent assumptions
Use the same borrowing amount, fixed-rate period and a clear repayment schedule. A lower monthly instalment may simply reflect slower repayment. The balance at the end of the fixed period therefore matters alongside the initial payment.
Check special repayments, repayment-rate changes, charges before drawdown and possible early repayment costs. Also clarify an intermediary’s remuneration and service scope. A comparison should show terms actually available to you, not just advertising.
4. Coordinate purchase, loan and drawdown
Distinguish an initial assessment from a lending decision and from satisfaction of drawdown conditions. Have outstanding conditions explained. Coordinate purchase payment dates and financing availability before relying on completion.
Keep the agreements, drawdown records and repayment schedule. Record the fixed-rate end and contractual deadlines. After purchase, review whether your reserve and ongoing budget still match your circumstances.

Frequently asked questions
What monthly payment can I afford?
Start with sustainable income minus expenses, other commitments and an appropriate reserve. Include the property’s ongoing costs. A fixed income percentage is not a substitute for a household budget or the lender’s assessment.
How long does mortgage approval take?
There is no universal guaranteed deadline. Completeness, property review and the lender’s process affect timing. Agree concrete next steps and clarify outstanding conditions before relying on a fixed purchase timetable.
Is the lowest advertised rate enough for comparison?
No. With equivalent assumptions, also compare remaining debt, total costs, fixed-rate periods, drawdown conditions and flexibility. Ask about costs not included in the stated effective annual rate.
