Renovations do not fail from bad math. They fail from no contingency.
Whatever timeline you think it will take, expect more.
Whatever budget you think it will cost, plan for higher.

Time.
Money.
Quality.
And renovations demand hands on management.
If you are not managing it daily, someone on your team must be.

Build contingencies into the timeline.
Build contingencies into the budget.
Know exactly who you are working with.
If you cannot manage it yourself, hire someone who can.
That is how you protect returns.
