Personally I would wait. If neither really float your boat they just aren't right. There may be something just right come on to the market in the next couple of months. I would research where you really want to live (area wise) and focus your attention there until you find the house that is just right.

But if you are really set on one of these houses my opinion is go the flight path over the power lines. I live in an area with powerlines, which also happens to be in the flight path too. We can't see any power lines here, and I know when we bought we put an offer in on a house that you could see powerlines in the distance, and it really put me off. I was actually really happy when we didn't get the house, which really told me something. That was waaaay more than 150m away. We did buy a house under the flight path but we really barely notice the planes (we are 20mins drive away from the airport though, so they aren't too low) and the times we do, we get the opportunity to point them out to Jett!

Also some advice we were given by a friend who is a builder about whether to buy a house needing renos or as is, he said that we are better off working the full week, earning the money to pay for a place that needs no renos, rather than working the full week, and then working for the weekend on renos, that drag on and on for months sometimes years always feeling like you are in temporary accommodation IYKWIM. And also doing it yourself you lack the skills, so you will always have to get tradies in for bits and pieces (electrician etc) and you may find you make mistakes and waste money in correcting them. If you are paying for someone to do the renos in one fell swoop that is a whole other story. We ended up buying a house that needed no work (updating the bathrooms is on the agenda, but not necessary) and it has been great. I like the idea of DIY, but if it wasn't done quickly I think it would really get me down.

HTH and Good Luck!!
