Prompt Template

You are a personal finance planner specializing in home renovation budgeting. Help me build a realistic renovation budget and contingency plan.

**Renovation project:** [kitchen remodel / bathroom / extension / whole home / energy upgrade / other]
**Location:** [city/country]
**Home type and age:** [apartment, townhouse, older home, etc.]
**Must-have scope:** [non-negotiable work]
**Nice-to-have scope:** [optional upgrades]
**Quotes received:** [contractor quote details, if any]
**DIY vs professional:** [what I can do myself vs must hire]
**Available cash:** [amount]
**Financing options:** [savings, HELOC, personal loan, credit card, family loan]
**Timeline:** [desired start/end dates]
**Risk factors:** [structural issues, permits, supply delays, old wiring/plumbing]
**Monthly cash-flow limits:** [how much can leave my account each month]

Create:
1. **Budget summary** — base cost, taxes/fees, permits, design, materials, labor, temporary living costs, and contingency.
2. **Quote comparison table** — normalize contractor quotes and identify missing line items.
3. **Contingency recommendation** — percentage based on project risk and home age, with rationale.
4. **Cash-flow schedule** — deposit, progress payments, final payment, and monthly impact.
5. **Scope tradeoff list** — what to cut, defer, downgrade, or DIY if costs rise.
6. **Financing decision guide** — compare options by cost, risk, flexibility, and repayment plan.
7. **Red flags** — contract, payment, permit, and insurance issues to verify.
8. **Decision checklist** — what must be true before signing.
9. **Stress test** — what happens if the project runs 15%, 25%, or 40% over budget.

Include a reminder to verify tax, permit, insurance, and legal details locally.

Example Output

Renovation Budget Summary — Bathroom Remodel

| Category | Estimate |

|---|---:|

| Contractor labor | €8,200 |

| Tiles, fixtures, vanity | €4,100 |

| Plumbing/electrical allowance | €1,600 |

| Permits/inspection | €350 |

| Waste removal | €450 |

| Temporary shower/gym access | €180 |

| Subtotal | €14,880 |

| Recommended contingency (20%) | €2,976 |

| **Target budget** | **€17,856** |

Quote Gaps to Clarify

- Quote A excludes tile disposal and waterproofing membrane.

- Quote B includes fixtures but uses a low allowance (€900) that may not match selected items.

- Neither quote states who pays if old plumbing needs replacement.

Cash-Flow Schedule

- 10% deposit at signing: €1,488

- 40% after demolition/rough-in: €5,952

- 40% after tile/fixture installation: €5,952

- 10% final after snag list: €1,488

Scope Tradeoffs If Costs Rise

1. Keep plumbing locations unchanged — highest savings.

2. Choose mid-range tile for secondary walls.

3. Defer heated towel rail.

4. DIY painting only after contractor work is complete.

Stress Test

At 25% overrun, total becomes €18,600 before contingency. This is manageable only if the nice-to-have mirror cabinet and premium fixtures are removed.

Tips for Best Results

  • 💡Older homes deserve a bigger contingency; hidden plumbing and wiring love surprise cameos.
  • 💡Normalize quotes before comparing — the cheapest quote often just excludes the scariest line items.
  • 💡Avoid paying too much upfront; progress payments should track completed work.
  • 💡Keep a separate “do not touch” emergency fund so the renovation does not eat your financial safety net.
