Mortgage after separation

Does anyone know what the best option is to purchase another house after a separation? I am paying for half the mortgage on the old house and I’m currently renting. Is there any scheme which would help seeing as the new mortgage will be my second and therefore require a 20% deposit.

If you are unable to put aside 20% towards a deposit, would you meet the banks' affordability criteria? There is no scheme that will get around that to purchase a second property.

Thanks Leo, I can borrow €107k based on my criteria but have to fund a Deposit of 20% so the property would have to be under €133k and I would have to fund €26k. Its nearly impossible to purchase again without having the Deposit and even at that €133k is not much to be buying a house with!
