What Is After-Repair Value (ARV) and Why Lenders Care About It

What Is ARV?

After-Repair Value (ARV) is the estimated value of a property after all planned renovations and repairs are complete. It is the 'finished product' value — what the property will be worth when you list it for sale or refinance it. ARV is the foundational metric for fix-and-flip lending because it determines how much capital a lender will provide.

If you are new to fix-and-flip investing, understanding ARV is non-negotiable. Every fix-and-flip lender — including MB4I — uses ARV to size the loan, determine your required equity, and assess whether the deal makes sense.

How ARV Is Calculated

ARV is estimated using comparable sales (com sales) — recently sold properties in the same market that are similar in size, condition, and location to what your property will be after rehab. The process is the same one an appraiser uses, and most lenders will order a formal appraisal to confirm your ARV estimate.

Here is the basic approach:

• Identify 3-5 comparable properties sold within the last 6-12 months, within 0.5-1 mile of your subject property.
• Adjust for differences: square footage, bedroom/bathroom count, lot size, garage, condition, and amenities. If a comp has a 2-car garage and yours has a 1-car, adjust the comp's sale price down to compare apples-to-apples.
• Calculate a price-per-square-foot range from the adjusted comps and apply it to your property's post-rehab square footage.
• The result is your estimated ARV. Lenders typically use the appraiser's ARV, not your estimate, for loan sizing.

How Lenders Use ARV to Size Loans

Fix-and-flip lenders typically lend based on the lesser of purchase price or ARV, with loan-to-cost (LTC) and loan-to-ARV (LTARV) caps. Here is how it works:

Loan-to-Cost (LTC): The loan as a percentage of total project cost (purchase + rehab). Typical LTC caps are 85-90% of acquisition and up to 100% of rehab.

Loan-to-ARV (LTARV): The loan as a percentage of ARV. Typical LTARV caps are 65-75%. This is the lender's downside protection — if the deal goes sideways, the lender wants to ensure the loan balance is below the property's finished value.

Example: You are buying a property for $200,000 with a $75,000 rehab budget. Total project cost = $275,000. Your estimated ARV is $400,000.

LTC calculation: 90% of $275,000 = $247,500 max loan.

LTARV calculation: 70% of $400,000 = $280,000 max loan.

The loan is capped at the lower of the two: $247,500. This means you need to bring $275,000 - $247,500 = $27,500 in cash (your equity contribution).

If your ARV estimate was $350,000 instead, the LTARV cap would be 70% × $350,000 = $245,000 — and the loan would be capped at $245,000, requiring $30,000 in cash. A lower ARV means a smaller loan and more cash required.

Why Conservative ARV Estimates Protect You

Many investors — especially first-time flippers — are optimistic about ARV. They use the highest comp in the neighborhood, assume their renovations will be flawless, and project a quick sale at top-of-market pricing. This is dangerous, and not just because it makes the lender uncomfortable.

If your ARV is inflated, you may overpay for the property, over-spend on rehab, and find that the property does not appraise at your projected value when it is time to sell or refinance. At that point, you are stuck — you cannot sell for enough to repay the loan, and you cannot refinance because the appraisal comes in low.

Conservative ARV estimation protects you in three ways:

• It forces you to buy at a price that leaves room for profit even if the market softens or your rehab costs run over.
• It ensures the loan you receive is sized appropriately — you will not be over-leveraged relative to the property's actual value.
• It gives you a buffer if the appraisal comes in below your estimate. If you projected $400,000 and the appraisal comes in at $380,000, a conservative estimate means you still have a viable deal.

Common ARV Mistakes

These are the ARV estimation errors we see most often:

Using the highest comp only: Cherry-picking the most expensive sale in the area ignores the range of values. Use a range and be honest about where your property falls within it.

Ignoring condition differences: If your comps are fully renovated and your property will be 'nice but not luxury,' your ARV should reflect that. Do not assume top-of-market finishes.

Using stale comps: Market conditions change. A comp from 18 months ago may not reflect current pricing. Stick to sales within the last 6-12 months, and adjust for market trends.

Ignoring days on market: If the highest comp sat on the market for 180 days before selling, it may not represent realistic pricing. Look at how quickly comps sold — that tells you what buyers will actually pay.

Forgetting to account for your rehab quality: If your rehab is a 'lipstick flip' (paint, flooring, fixtures) but your comps are full gut renovations, your ARV should be lower than the comps, not equal to them.

The 70% Rule

Many fix-and-flip investors use the '70% rule' as a quick ARV-based offer formula: Maximum Offer Price = (ARV × 70%) - Rehab Cost.

For a property with $400,000 ARV and $75,000 rehab: Max Offer = ($400,000 × 0.70) - $75,000 = $205,000.

The 70% rule accounts for the 70% LTARV cap, rehab costs, and a margin for closing costs and profit. It is a useful sanity check, but it is a rule of thumb — not a substitute for a detailed deal analysis. In hot markets, you may need to offer more than 70% to win deals. In slower markets, 70% may be too aggressive.

Use the 70% rule as a starting point, then refine with a full deal analysis that accounts for your actual rehab budget, carrying costs, selling costs, and target profit margin.

Bringing It Together

ARV is the foundation of every fix-and-flip deal. Estimate it conservatively, support it with real comps, and understand how your lender uses it to size the loan. If your ARV is realistic, your deal will be sized appropriately and your profit margin will be protected. If your ARV is inflated, you are setting yourself up for a shortfall at the finish line.

If you have a fix-and-flip deal and want a second opinion on your ARV estimate, submit an inquiry. We will review your comps and tell you whether your numbers are realistic before you commit.
