Count the full cost of moving, not the price difference
Homeowners compare the price of the bigger house against the value of theirs and conclude that moving is cheaper. That comparison leaves out most of the actual expense.
Transfer duty on the new property, conveyancing and bond registration fees, the estate agent's commission on the sale, the bond cancellation, the physical move, and the near-certain list of things you want to change in the new place. Add those up honestly before you decide.
- Transfer duty on the purchase
- Conveyancing and bond registration
- Agent's commission on your sale
- Bond cancellation and penalty interest
- Removals, storage and immediate remedial work in the new home
Renovating usually wins when the location is right
If you like where you live, the schools work, the commute works and your neighbours are decent, that is worth a great deal and it does not transfer. Most people who move for space discover they have traded a location they loved for rooms they use twice a year.
Renovating spends the whole budget on the building rather than on transaction friction. Very roughly, a large slice of a moving budget disappears into costs that add nothing to your living space at all.
Moving usually wins in three situations
There are cases where renovating is the wrong answer and a good builder should tell you so.
- The plot itself is the constraint: you have hit coverage or building lines and cannot go up
- You would be over-capitalising well beyond the ceiling price of the street
- The thing you actually need is a different area, not a different house
The ceiling price question
Every street has a price above which buyers simply do not go, no matter how good your finishes are. Spending your way past it means the money does not come back when you sell.
This matters much less if you plan to stay for fifteen years and enjoy the house, and enormously if you are likely to move in three. Be honest with yourself about which one you are.
The middle option people forget
You do not have to choose between a full renovation and a move. Reclaiming a garage, converting a loft, or enclosing a patio can add the one room that was actually missing at a fraction of the cost of either.
Before committing to anything large, work out precisely which room you are short of. The answer is often smaller and cheaper than the plan you started with.
