Hi Jane09,
You could certainly try before the 12 months with PTSB. If you get to the point PTSB will definitely not accept you, could then look to save with another bank and try them for a mortgage. There is no harm in politely checking in every so often. PTSB were sympathetic to my case, but I have periodic checkins with UB and BOI also, just to keep the relationship going. Sometimes they might say contact them again in 6 months, or when your finances are at a certain point. KBC said they would never do business with me, but then again different branch reps can give different answers.
With any bank, if they see the money coming in then that's good enough, if money is going out to separate savings account then that should be fine so I would say no need to change that.
You can request your ICB report online for a nominal fee (6Eur or something like that), while banks will be doing their own checks, at least you can highlight how good (apart from bankruptcy) the finances are.
Unfortunately because you are married, with the homeowners act, you need to make a joint application. Depends on how desperate you are for a mortgage - divorce could solve your problem
yes loans and ccard do get listed on your ICB, but is pointless getting a 1k loan and paying it back as the value is listed also. They will be looking for longer term history.
I'd say you should aim for 20% deposit
Definitely meet sales managers from each bank and listen to what they have to say.
Beware of independent financial advisers as they may be more negative on options.
Best of luck
