First time mortgager, help please...!

Okay dudes, the frau and I are looking to buy when we relocate to another area soon, but as I've (we've) never had a mortgage I was hoping people could help and advise a little....

I earn 38k and the wife 15k and are totally debt free with a deposit of 10k. What sort of ballpark repayment mortgage could we get with those figures? Do banks still lend at 3xannual salary or am I living in the past??

MTIA....
