Reno budget

If I bought a house which needs the following, how much would you budget for IP reno of:
- Kitchen (cabinets and fixtures) - say 8 std cabinet + 60cm stove
- Bathroom - smallish, tile to mid level (or is full height the done thing?) - handbasin, toilet, long bath, shower with nib wall to be removed & replace with glass screen from bath height
- electrical rewiring (whole house)
- possible plumbing replacement (not moving anything)
- remove carpet & polish floors
- repaint (we know think sub- $5K)

Partner says $50K, is that doable?

Other possible extras:
- replace/repair double hung timber windows
- retaining wall remove & replace (12m length, up to 1m high) - currently double brick front fence.

More info - simple double brick cottage, elevated so there is access underneath for services, timber tongue & groove flooring. 3 bedrooms, separate lounge & dining rooms, hallway. In Sydney.

 

Yep $50k - $60k depending on how much of the services to replace. Old house needs new switchboard, rewiring, perhaps replace galvanised water pipes with copper etc.

Been involved with 3 of these in past year - also consider need to replace fascia, gutters, hot water service and remove asbestos.
