What these figures mean

A starting point,
not the full picture

Calculators are useful — but the rate you actually get, and what you can genuinely borrow, depends on far more than income and loan size.

01
Rate availability
The rate you see advertised is rarely the rate you get. It depends on your LTV, credit profile, and the lender's appetite for your case. We find what you can actually access.
02
Complex income
Self-employed, contractors, directors, and multiple income streams are assessed differently by each lender. We know which lenders are genuinely flexible — and how to package your case.
03
Credit history
Defaults, missed payments, and previous declines all affect your options — but not as much as you might think. We assess the full picture and approach lenders suited to your profile.
04
Expat & overseas
UK nationals living abroad face additional lender restrictions. We specialise in this — including clients based on the Costa del Sol seeking UK residential or investment finance.
