To give you an idea on repayment, pm your email. I'll got some fancy spreadsheets you might be interested in having a look. Thats a very decent deposit Andy. I remember when I bought my house early this year, I only had 10k + whatever the gov gave me. Hahaha. The rest went into reno and car of course.
Maybe come to the car wash tonight and we can chat about these. My opinion on property is location and structure would be the highest priorities. If they're brick/struturely stable, nothing a bit of money on reno wouldnt do to make it look heaps better. And of course with location, you'll only get something is well located if someone decided to sell theirs.
