firstly, thanks for all the advice...
I took it up with the agent, and raised the issue of knocking down the price by a few k... he rang me back and said there's no way the vendors will come down...
the value of this property is mainly in the land... i could easily put another place on the back if i cut the back yard in half (there's access via a laneway out the back...)
other properties in similar condition that I looked at while there were on half the land size and selling for 70k in the same street...
the house is perfectly fine to rent out now as is (already has a tenant who I met while there, loves the house and reckons she isn't going anywhere)...
some of the houses in rocky are now being sold around the 65k-70k mark that are well and truly in flood zones... mine's not...
also, spoke to another person up there who knows the house, and reckons it's not like the roof is akin to a piece of swiss cheese (which concurs with the inspector said)... he reckons rust is a problem with a lot of houses in rocky to some degree... he said there's a special treatment that can be done, sort of like painting, that'll cost about $600... he had it done to one of his IPs there and said it came up a treat (no, this guy isn't a REA), so that's the path I'll take...
thanks again,
