As my boyfriend and I wanted a 100% mortgage - we initially queried through 2 brokers our options.
Note: Boyfriend, wasn't a first time buyer. I was.
Brokers advised that we wouldn't get one, from any bank. As both had to be FTB's.
Few weeks later, a Sunday paper, included a supplement on Mortgages, and outlined everything u'd need to know. 1 particular point that stood out, was PTSB would give 100% mortgages to borrowers, as long as one of the borrowers was a 1st time buyer.
On finding this out, I rang up PTSB, and low and behold told YES, you can get a mortgage!!
