James, although you have an excellent deposit (25%) many lenders may baulk at your varied income as they won't like the fact that you are applying for a £150k mortgage yet some months may only earn £1,000!

My advice to you would be to go and speak to your own bank (where your income is paid in). They have a direct history of you as a client and payments into your current account. From that information they should be happy to offer you a mortgage in principle based on firm and positive financial information through your history with them. 'If' you take out a fixed rate or variable rate deal with them which they are happy to offer you and you are happy that you can afford, then there will be no problem with you making additional or increased payments into the account in those better months where you are particularly flush. With your varied income the lender may advise on a fixed rate deal for you to start off with though.

Good luck.

Hello

I am sure the topic has been done to death but had a quick search and seen some people are very helpful. I am a first time buyer and looking to buy a £200k place and have a £50k deposit. My job is mainly commission based and my earnings fluctuate between 1-10k month. It is a steady job and i have been looking at different mortgages but with a lot of confusion and dont know if i should take fixed rate/variable/one account. I would ideally like to be able to pay off more one month and then less the next dependant on earnings.

Does anyone have any experience or advice for my situation?

Thank you in advance

James
