How to Read the Results

MAO (Maximum Allowable Offer): The most you should pay, given your ARV and rehab estimate, to keep all-in costs below the refinance threshold. This is a starting point — the actual offer depends on negotiation and verified comparables.

All-In as % of ARV: This is the critical number. Keep it below your refinance LTV (typically 75%) and you will recover all your capital at refinance. The gap between your all-in percentage and 75% is your margin of safety.

Capital Recovered: The refinance loan proceeds minus your purchase price, rehab, and carrying costs. Positive means you get money back. The BRRRR goal is to recover 100% (infinite return) or close to it.

DSCR: Debt Service Coverage Ratio. Most conventional and DSCR lenders require rent ≥ 1.20× the monthly P&I payment. Below 1.0x means the property doesn’t cover its own mortgage — a red flag for both lender qualification and cash flow.


Gulf Coast BRRRR Considerations

Verify ARV with closed comparables — not active listings, not Zestimate. Pull closed sales within the last 6 months, similar bed/bath count, within 0.5 miles if possible. Your refinance appraisal will be based on these same comparables; an inflated ARV is the most common BRRRR failure point.

Build contingency into rehab — Gulf Coast humidity means hidden moisture issues are common in distressed properties. A 15% contingency is the minimum; use 20% for properties vacant more than 12 months or with unknown history.

Confirm flood zone before acquisition — at msc.fema.gov. A property in an AE or VE flood zone has materially higher insurance costs that change the cash flow analysis post-refinance.
