If you have a question about what you can borrow, please get in touch. Our visitors often have complex income situations and it can be difficult to establish which income is acceptable, especially for those who are self-employed, or earn variable amounts of overtime/allowances/commission/benefits etc. or money overseas.

It’s important to remember that every lender is different, and not all will accept 100% of every piece of income you get. Some will take 100% for one thing, 60% for something else, and 0% for another, where another lender may take 100% of all 3. Getting the right lender to fit to your income is important as it can mean the difference between the mortgage you need and settling for less. Don’t settle. We only work with mortgage brokers that have access to the whole market, and with years of experience in helping borrowers get the mortgage they need you know you’ll be in good hands.

If you’re ready to make an application or if you just have an enquiry, please click the button below and one of the specialists will be in touch ASAP. If you require immediate assistance please give us a call.

Some types of buy to let mortgages are not regulated by the FCA. Think carefully before securing other debts against your home. As a mortgage is secured against your home, it may be repossessed if you do not keep up with repayments on your mortgage. Equity released from your home will also be secured against it.
