Quick guide

How to use this calculator

  1. Enter a single internally consistent property scenario.
  2. Use the field labels to preserve each page's specific investment, transaction, lease, development, or lodging convention.
  3. Review the calculator-specific boundary before interpreting the result.

Calculation method

Calculation method

New loan = ARV × refinance LTV; net refinance proceeds = new loan − acquisition-loan payoff − refinance costs; cash left = acquisition and rehab cost − new loan + refinance costs.

Entered fixed decimals use exact rational arithmetic except the explicitly approximate IRR root. Money rounds only for display and supported nonzero amounts remain visible.

Worked example

Worked example

A 150,000 financed purchase, 40,000 rehab, 10,000 acquisition costs, 260,000 ARV, 75% refinance, 150,000 payoff, and 5,000 refinance costs leaves 10,000 in the deal and releases 40,000.

New loan = ARV × refinance LTV; net refinance proceeds = new loan − acquisition-loan payoff − refinance costs; cash left = acquisition and rehab cost − new loan + refinance costs.

Supported inputs

Precision and limits

Visible input limits

Amounts accept up to 30 digits and 12 decimal places and are capped at 1e12 per input. Whole-number periods are capped at the page's stated range; rates are capped at 1000%.

International scope

No currency, tax regime, lease law, lender threshold, local market feed, appraisal, or jurisdiction-specific charge is assumed.

Decision boundary

Results are visitor-entered arithmetic scenarios, not appraisals, forecasts, loan approvals, legal or tax determinations, or investment recommendations.

Calculator-specific assumptions

The simplified cash-left formula assumes the entered payoff is acquisition debt already included in purchase cost, so it is not added to project cost again. Refinance terms are a scenario, not a lending quote.
