Lenders look at 3 things
1. Loan to Value (LTV) which in your case is low as you have a big deposit
2. Income multiple (IM), on 45k you have strong IM for a purchase of 160k with 100k deposit.
3. Affordability – the car loan is high so this will go against you, you might want to think about clearing the loan with your savings or find a lender that’s not too worried about it.
There’s usually a penalty for early withdrawal form fixed term deposits where they give you less interest than they otherwise would have had you stayed the full year, up to you to weigh up pros and cons.
You would have a strong case and all the main lenders would want to lend to you. There are some decent looking 3 year fixed rates at around 3% that I’m thinking of going for.
