So I've heard various opinions on google about anti-con, from what I hear it helps with 1) noise (rain etc) 2) moitsure in roof and 3) most importantly for many the insulation factors. Now I've been quoted $5,185 on providing anti-con roof insulation to the entire home. I plan to have it as an IP and am adding in 'smart' value where I can see it may future proof if I ever live in it, if not too much of a biggie if it stayys as an IP. I'm torn between whether anticon is required. On a 220k build an extra $5k is a huge hit for many building as some may imagine.... Can anyone offer an opinion/advice on the pros/cons on anticon, and most importantlyy if it makes reasonable investment sense to add it in? There's always the odd idea of reselling, but my plan was to hold any property indefinitely as an investment (so selling may only be a change of circumstances etc.). Just trying to make the best decision... i think I'd like to keep it as an IP... but the location is ok for moving into if i get married.
