The LTI limit restricts the amount of money you can borrow to a maximum of 3.5 times your gross income. So for example, a couple with a combined income of €100,000 you can borrow up to a maximum of €350,000.
Once again banks and other lenders have the freedom to lend a certain amount above these limits. In any one calendar year they can give an allowance to:
Up to 20% of the value of mortgages to first-time buyers
Up to 10% of the value of mortgages to second and subsequent buyers
Unless somebody knows something I don't, single people can borrow up to 3.5 times their gross income.
OP, don't pay any heed to what other people say. This is your life and your decision to make. Back in the mid-2000s I was in a position to buy my first home but I decided against it because I believed the property bubble was about to burst. That didn't stop me from having well-meaning relatives in my ear, urging me to buy before it was too late. Rent was dead money, I was paying somebody else's mortgage, there's never a bad time to buy a house etc. As it turned out, I was right and I was safer renting when the economy went to hell in a handcart. I didn't hear a peep out of these relatives after that. I know that some of my cousins/their kids ran into problems with their jobs or saw the value of their houses take a nosedive. What I'm trying to say in a roundabout way is that you'll have no shortage of people offering opinions on what they think you should or shouldn't do. This isn't their decision to make - it's yours. It's your life and you are the one who has control over what you do with it. From now on it'd be better to keep your cards close to your chest and quietly continue to save.
As you can see, buying a first home is doable. You'll need to cut your cloth to suit your measure but I'm sure you'll get there. The one thing I'd advise you to do from now is to get your bank accounts and credit card statements into a "mortgage friendly" condition. If you have any overdrafts or loans, clear those if you can. Set up a direct debit and ensure a fixed amount of money goes from your current account to a savings one every month. Avoid online gambling or anything else that might attract attention. When the time comes to buy a home, you'll need to leave around €5k aside to cover solicitor's fees, surveyor etc.
