ARV 101: How Lenders Calculate After-Repair Value and Why It Drives Your Loan

If you do one thing before submitting a fix and flip deal to a hard money lender, understand after-repair value. ARV is the estimated market value of the property after all planned renovations are complete. It is the single most important number in the deal — more important than your purchase price, more important than your rehab budget, and more important than your experience level. ARV determines how much the lender will fund, and it determines whether the deal makes financial sense for everyone involved.

Here's how lenders actually calculate ARV, how the process works behind the scenes, and how you can submit deals that get approved faster with stronger terms.

Why ARV Matters More Than Purchase Price

Hard money lenders don't lend based on what you're paying for the property. They lend based on what the property will be worth when you're done with it. The loan-to-value ratio (LTV) is calculated against ARV — not purchase price.

This is fundamentally different from how a conventional mortgage works. A bank cares about the current appraised value. A hard money lender cares about the future value, because the exit strategy — your sale of the finished property — is how the loan gets repaid.

When a lender says they'll lend up to 70% LTV, they mean 70% of the ARV. If the ARV is $300,000, the maximum loan amount is $210,000. That $210,000 has to cover your acquisition cost and your rehab cost. If you're buying at $150,000 and renovating for $50,000, your total project cost is $200,000 — well within the $210,000 ceiling. If your rehab budget is $80,000, your total cost is $230,000, and you'll need to bring the difference to closing.

How Lenders and Appraisers Determine ARV

ARV is determined by comparable sales — recent transactions of similar properties in similar condition in the same area. The process is the same whether it's a full appraisal ordered by the lender or an internal desk review done by the underwriting team. The appraiser or underwriter pulls sold comps, makes adjustments for differences, and arrives at a value.

The key word is "sold." Not listed. Not pending. Sold and closed. Active listings tell you what sellers hope to get. Sold comps tell you what buyers actually paid. Lenders care about the second number.

What Makes a Good Comparable Sale

Not all comps are created equal. Lenders and appraisers rank comps by relevance, and the strongest comps share these characteristics:

• Same neighborhood or subdivision. A comp one street over is worth far more than a comp two miles away, even if the second one is a closer match on specs.
• Similar square footage. Within 10-20% of the subject property. A 1,200 sq ft house is not comparable to a 2,400 sq ft house regardless of other similarities.
• Sold within the last 6 months. In fast-moving markets, lenders prefer 3-month comps. In slower markets, 6 months is acceptable. Anything over 12 months is essentially useless.
• Similar condition post-rehab. This is critical. The comp needs to reflect the condition your property will be in after renovation — renovated, updated finishes, move-in ready. A dated, unrenovated sale is not a valid ARV comp.
• Similar bed/bath count and layout. A 3-bed/2-bath should be compared to other 3/2s. Adding a bedroom or bathroom changes value significantly.

How Appraisers Adjust for Differences

No two properties are identical, so appraisers make dollar adjustments to account for differences between the comp and the subject property. These adjustments are the heart of the valuation process.

Adjustments are market-specific. In a market where extra square footage commands $80/ft, a comp that's 200 sq ft smaller gets adjusted upward by $16,000. In a market where it commands $35/ft, that same difference is only $7,000. Appraisers use local market data, not national formulas.

Investor ARV vs. Appraised ARV

Here's where deals run into trouble. The number you put on your deal submission is your investor ARV — your estimate of what the property will be worth. The number the lender uses is the appraised ARV — a licensed appraiser's independent opinion of value, or the lender's internal conservative estimate.

These two numbers rarely match exactly. Investor ARVs tend to run 5-15% higher than appraised values. Why? Because investors naturally gravitate toward the highest comp, assume the best-case scenario, and factor in market appreciation that hasn't happened yet. Appraisers and lenders use conservative methodology because they're protecting a loan — they need the value to hold up even if the market softens.

This gap is normal. The problem is when the gap is large enough to break the deal's math.

Worked Example: A Typical Fix & Flip Deal

Let's walk through a real scenario to show how ARV drives the loan amount.

• Purchase price: $150,000
• Rehab budget: $50,000
• Investor's estimated ARV: $280,000
• Appraised ARV (lender's number): $270,000
• Lender's max LTV: 70% of ARV

Maximum loan amount: $270,000 × 70% = $189,000

Total project cost: $150,000 + $50,000 = $200,000

Cash the borrower needs to bring: $200,000 - $189,000 = $11,000 (plus closing costs)

If the ARV had come in at $250,000 instead, the max loan drops to $175,000 — and the borrower needs $25,000 plus closing costs. That $20,000 swing in ARV created a $14,000 difference in required cash. This is why ARV accuracy matters.

Common ARV Mistakes That Kill Deals

After underwriting thousands of deals, these are the ARV errors we see most often:

• Using comps too far away. A sale three miles away in a different school district is not a comp. In suburban and rural markets, distance matters even more.
• Using active listings instead of sold comps. A listing at $320,000 means nothing until it closes. It could sell for $290,000 or sit for six months and expire.
• Overestimating rehab quality. If your comps have custom tile work and quartz countertops but your budget has basic LVP and laminate, the finished product won't match the comp. The appraiser will notice.
• Ignoring market direction. Using a comp from eight months ago in a declining market means your ARV is already stale. Markets move, and appraisers consider the trend.
• Cherry-picking the highest comp. One outlier sale doesn't set the market value. Appraisers use multiple comps and weight them. If three comps say $260K and one says $310K, the ARV is around $265K — not $310K.
• Forgetting functional obsolescence. A 900 sq ft, 2-bed/1-bath house in a neighborhood of 1,500 sq ft 3/2s has a ceiling no amount of renovation can fix. The floor plan limits the value.

How to Strengthen Your ARV Case

You can significantly improve your deal submission — and your approval speed — by doing the appraiser's homework for them. Here's how:

• Include your own comps. Pull 3-5 sold comps from the MLS or public records. Include the address, sale price, sale date, square footage, bed/bath count, and condition. Show that you've done the research.
• Attach photos of comparable properties. If the comps are renovated to a similar standard as your planned rehab, photos prove it. MLS listing photos from the comp's sale are ideal.
• Submit a detailed scope of work. Your SOW should show that the finished product will match the comp quality. If your comps have granite and stainless, your scope should include granite and stainless — not "kitchen update TBD."
• Note your finish level explicitly. State that you're targeting "retail-grade finishes consistent with renovated comps in the $270K-$290K range." This tells the underwriter you understand the market.
• Flag market conditions. If the area is appreciating, include data. Days on market trending down? Median sale price increasing quarter over quarter? Include it. If the market is flat or declining, don't pretend otherwise — acknowledge it and explain why the deal still works.

How SGC Evaluates ARV

At Southern Ground Capital, we evaluate ARV conservatively but fairly. Our underwriting team reviews every comp in your submission, pulls additional comps independently, and arrives at a value we're confident will hold up at sale. We don't use the highest number to make the deal look good. We use a number we'd bet on.

That said, we're not adversarial. If you submit strong comps with solid documentation, our number will typically be close to yours. If there's a gap, we'll explain why — and we'll work with you to see if the deal still pencils. A strong comp package with photos, a detailed scope of work, and realistic numbers is the fastest path to a term sheet.

We've seen plenty of deals where the borrower's ARV was aggressive but the underlying deal was sound. In those cases, the conversation is quick: we share our number, the borrower adjusts their cash-to-close, and we move forward. The deals that stall are the ones where the borrower can't explain where their number came from.
