1. Determine Your Budget
An incomplete budget or estimate is the biggest cause of budget overruns and delayed schedules. So, in setting your budget, do as much window-shopping and cost-comparisons as possible before you begin and have clear in mind what you expect. Add an extra 20% for extra costs that are likely to pop up. Once you have your budget in mind, communicate this with your builder on a regular basis to keep your budget on track throughout your renovation.
