Quick Answer
Buy-to-let investment in Cardiff requires a minimum 25% deposit for most lenders. Rental yields vary by area. Use our BTL mortgage calculator to estimate monthly costs and potential profit.
- Loan-to-value bands (95/90/85/80/75%) drive pricing — check the nearest band boundary
- Whole-of-market brokers see deals comparison sites don't carry, especially for non-standard income
- Get a soft-search decision in principle first — it costs nothing and reveals problems early
Beyond the Basics
New-build purchases carry extra moving parts: developer deadlines (often 28 days to exchange), incentives that lenders may deduct from the valuation, and the need for extended offer validity. Tell your broker it's new-build on day one.
Post-2023 affordability testing is stricter than many buyers expect. Lenders now stress-test your payments at a rate above your actual deal, and regular commitments — car finance, childcare, even subscriptions — reduce the maximum loan. Clearing a £300/month car payment can add £15–20k to a mortgage offer.
Nothing moves your rate more than loan-to-value. Lenders price in bands — 95%, 90%, 85%, 80%, 75% — and crossing a band boundary can cut your rate by 0.3–0.6 percentage points. Before applying, check whether a small top-up to your deposit crosses a threshold: on a £250,000 loan that's thousands over a fix.

Frequently Asked Questions
You don't have to use one, but a whole-of-market broker sees deals that never appear on comparison sites, and knows which underwriters accept your income type. For non-standard income it usually pays for itself.
Almost all fixed deals allow 10% overpayment per year without penalty. Overpaying early in the term saves the most interest.
Typically 3 to 6 months depending on the lender. New-build purchases often get extended validity because completion dates slip.
Usually yes, but the pool of lenders shrinks. Specialist lenders accept defaults and CCJs older than 12 months, typically at higher rates. Rebuilding your score for 6–12 months first often saves thousands.
A decision in principle usually uses a soft check, which leaves no mark on your score. The full application is a hard check — so avoid multiple full applications in quick succession.
