What level of saving do you have?
What ages are you and your husband?
You will need a significant deposit, and the ability to pay back the full loan before 66 to even be considered for a loan.
The interest would probably be btl so higher than a ppp mortgage, boi say 5.8% on their website.
So a mortgage of €350K say with a deposit of €70K (20%), over a 17 year term, guessing age of 49, will give you repayments of €2K per month.
As well as the €70K, you will need to fees, etc on purchase, then furnish and fit it out, then cover utilities etc. and if you rent out other rooms you can only take in €14K per annum.
So can you decide if you can afford it first.
Then if child 1 and 2 go to Galway, will child 3 & 4? Or will you have 2 in Galway, 1 in Sligo and 1 in Dublin?
So will you end up with added costs? And if you decide to sell in 6 or 8 years, will you loose money (house prices can go down too). Is it an investment at the end of the day or something nice to have - a family home for your children to live together during college?
