All lenders must follow Central bank deposit rules, which require a 10% deposit for first time buyers. So, if the value of your property is €200,000, you’d need a deposit of €20,000. This deposit can come by way of a gift, or part gifted, if you are lucky enough to have some-one willing and able to help you out. Borrowing for your deposit will not be acceptable to your mortgage lender, no matter where you are borrowing for.
