Structural soundness
It's wise to get independent pest and building reports done, even if the owners have already done these. Consider the reports as double-checking to ensure any red flags are spotted, which could affect your renovation goals. Having these reports handy gives you as much information as possible to guide your renovation decision-making.
What's your layout?
If you can find a home with the layout you like, you're already a significant step forward with renovations and budgeting. If you need to change your home's layout — we're talking plumbing and gas lines, wiring, adding a bathroom and more — the cost will quickly rise.
Future-proofing
If your family plans to live long-term in your renovated home, future-proofing is a cost-effective way of approaching your planning. For example, you may think of a playroom if you have toddlers. Later on, the playroom might be better off as a study or gaming room. Ensuring the room can adapt to your family's changing circumstances can save money by avoiding extensive modifications.
