We used to own an old weatherboard house @Kim and happily would again. Obviously there's extra maintenance compared to brick, particularly painting, but paint is so good these days that's not going to be required very often. Our old place was not as easy to keep warm and cool as a brick house too, but I would expect a new place to be very well insulated so there might be little difference between a brick-clad home. Being new I would also seriously doubt if you are going to have any issues with pest control or damp at any time down the track - but obviously these are problems that can affect old weatherboard places. I will be interested to see if anyone else has any significant concerns with your place. Good luck with your offer.
