Buying a home and wondering how much the reno's will cost us

Hi,

We are very close to purchasing a three bedroom brick house built in the 1980's. We believe the price is fair but there are some small renovations that would need to be done. I am hoping some of you who have personal experience with these renovations might be able to give me an idea of the price we may have to pay.

So renovations planned are as follows:
1: Rendering the 176 square meter house
2: Installing a dishwasher in place of some of the storage cupboards in the kitchen.
3: Installing a new toilet (the old one is a horrible green plastic toilet) and re-tiling the toilet room (very small room)
4: The house has modern split system r/c heating and cooling system. This is in the lounge room. We arent sure how it would go heating and cooling the whole house. So in case it doesn't do an effective job we want to get an idea of how much it was cost to install a 2nd device. Or how much it would cost to install ducted heating and cooling through the whole house.

Any help anyone can give would be much appreciated

Thanks

If it may help the link below is a video the real estate agent put together showing the various features of the house etc.

It's been a while since we rendered and we paid $12,000 but it was a big house and highset. We just got ducted in a 4 bed house $8,500 all up. But we have used the guy before and paid cash. Just guessing on the tradies prices for the kitchen and plumber. Might be a bit more for labour. Get a few quotes.

I recommend to have contractor. Ask them, to look at the house and they will give you a real estimate before you buy. That will make your process more easier and tension free. I made an estimate with the help of the professional contractors (Silverado Custom homes) at Toronto.
