Warnings to note

  • Renovation costs can overrun. Contingency is only a planning allowance, not a quote.
  • Consent, building, contractor, insurance and compliance issues can change cost, timing and usable rent.
  • Lease-up delay or vacancy can reduce early rent gains after the renovation.
  • Post-renovation value is an assumption, not a valuation or lender-accepted figure.
  • Refinance is not guaranteed. It depends on valuation, lender rules, serviceability, rates and loan terms.
  • Post-renovation rent is an assumption. Tenant demand and market rent can differ from the estimate.
  • Tax treatment is not fully modelled. Repairs, improvements, interest and ownership rules can vary.

How this renovate-to-rent calculator works

The calculator compares current rent and cash flow with post-renovation rent and cash flow, then layers in renovation budget, contingency, holding costs, lost rent, value uplift and a refinance assumption.

The cash-flow result uses monthly rent after vacancy, monthly operating expenses and a simple monthly interest cost from the loan amount and annual interest rate entered. It does not include principal repayment schedules.

The refinance result uses the post-renovation value and target LTV you enter. It is assumption math only, not a valuation, approval or lender quote.

What this calculator is useful for

Use it when the question is whether a renovation improves a rental hold through higher rent, better cash flow, possible value uplift and a refinance assumption. Use the House Flipping Calculator for renovate-to-sell scenarios.

What this calculator does not include

This calculator provides general estimates only. It does not predict rent, building costs, consent requirements, tenant demand, valuation acceptance, refinance approval, tax treatment or sale proceeds.

Renovate-to-rent focus
This calculator compares a renovation-to-hold scenario. It is not a sale-profit or flip calculator.
Cash-flow estimate
Cash flow uses monthly rent after vacancy, monthly operating expenses and a simple monthly interest-cost estimate before tax and principal repayments.
Renovation cost
Renovation cost with contingency is added to holding costs and lost rent during the project to estimate total project cash cost.
Value uplift
Current and post-renovation values are user-entered assumptions, not valuations, appraisals or lender-accepted figures.
Refinance assumption
Cash left in the deal is estimated from post-renovation value, target LTV and loan amount. It is not lender approval.
Region settings
Region settings change defaults, labels and currency formatting only. They do not convert exchange rates or create local property, lending or tax rules.
General estimate
The calculator does not predict rent, renovation costs, tenant demand, consent requirements, valuation acceptance, refinance approval, tax treatment or sale proceeds.

FAQs

What does this renovate-to-rent calculator estimate?

It compares current and post-renovation rent, cash flow, renovation spend, value uplift and a refinance assumption for a rental-hold scenario.

Is this the same as a house flipping calculator?

No. This tool is for renovating and holding a rental property. Use the House Flipping Calculator for renovate-to-sell or fix-and-flip scenarios.

Does this guarantee higher rent?

No. Post-renovation rent is an assumption you enter. Tenant demand, local market rent and lease-up timing can differ.

Does this guarantee refinance approval?

No. The refinance result is only scenario math from estimated value and target LTV. It does not confirm valuation acceptance, lender rules, serviceability or loan terms.

Should I include renovation contingency?

Usually yes. Renovation projects can overrun, so a contingency helps show how extra cost could change payback, cash left in the deal and risk.

Does this include tax?

No. This calculator is before tax and does not model repair or improvement tax treatment, GST, depreciation, bright-line rules or ownership structures.

Is this renovation or investment advice?

No. It is a general estimate based on the values entered, not building, legal, tax, mortgage, insurance, property or investment advice.
