ARV: How Appraisers Set It, and How to Contest a Low One
Your after-repair value is the single number that caps your loan, and it is produced by someone who has never seen your budget.
Understanding how the appraiser gets there — and what they are structurally unable to consider — is what separates investors who model ARV accurately from those who are surprised by it.

What ARV is
The appraiser's opinion of what the property sells for once your scope of work is completed competently.
They review your scope, then value the finished property against comparable sales using the sales comparison approach.
Your spending does not appear. This is the fact investors resist most. A $110,000 rehab that produces $70,000 of market value produces a $70,000 lift. Cost and value are different things, and appraisers are valuing the second.
How the number is built
Step 1: comparable selection
The appraiser looks for recently sold properties similar in location, size, age, style, condition and configuration.
Preferences, roughly:
- Within half a mile, closer in dense areas
- Sold within six months, three preferred in a moving market
- Same school attendance zone, which matters more in Central Texas than distance does
- Similar square footage, ideally within 10-15%
- Same bedroom and bathroom count
- No distressed sales where avoidable — foreclosures and short sales are typically excluded or adjusted
Step 2: adjustments
Each comp gets adjusted toward the subject. A comp with an extra bathroom gets adjusted down; one with a smaller lot gets adjusted up.
Adjustments come from market-derived data, not a price list. The appraiser is estimating what buyers in this market pay for that difference.
Step 3: reconciliation
The appraiser weights the adjusted comps — usually leaning on the most similar — and reconciles to a single value.
They are not averaging. A comp requiring few adjustments carries far more weight than one requiring many.
Why ARVs come in low
Ranked by how often each is the cause:
1. Comp scarcity. The most common by far. In a neighborhood with little recent turnover, unusual properties, or a wide range of housing stock, the appraiser cannot find three good comps and reconciles conservatively.
2. Over-improvement. You finished to a standard the block does not support. If the best sale on the street is $380,000, a $460,000 finish does not appraise at $460,000. The neighborhood caps you.
3. Square footage discrepancies. Your addition was unpermitted, or the county record disagrees with reality. Unpermitted square footage is frequently excluded entirely, which can erase a large part of your value creation.
4. Functional obsolescence you did not fix. A two-bedroom on a street of three-bedrooms. A bathroom only reachable through a bedroom. A tandem garage. Cosmetic work does not fix layout.
5. Market movement. Comps are backward-looking. In a softening market the appraiser is working from sales that closed when conditions were better, and reconciling downward.
6. Incomplete scope at inspection. If the appraiser walks a property where the scope is only half done, they may value what they see rather than what you described.
Contesting a low ARV
It is called a reconsideration of value, and it works sometimes. Not often, but sometimes — and it costs you a few hours.
What can work:
- Better comparable sales the appraiser missed. This is the only argument with a real success rate. Provide specific closed sales with address, close date, price, square footage, bed/bath, and a sentence on why each is more similar than what was used.
- Factual errors. Wrong square footage, wrong bedroom count, wrong lot size, a garage listed as unfinished when it is finished. These are correctable and appraisers correct them.
- Scope misunderstood. If the appraiser valued a partial scope because the write-up was unclear, a clearer scope with specifications can prompt a revision.
- A comp used that should not have been. A distressed sale, a family transfer, a property with undisclosed condition issues.
What does not work:
- "I spent $110,000." Cost is not value.
- "I need $X for the loan." Not an appraisal input.
- "Zillow says more." Automated estimates are not evidence.
- Pressure. Appraiser independence rules exist specifically to prevent it, and attempting it can taint the file.
Process: submit through your lender, not directly to the appraiser. Most lenders have a form. Expect 3-7 days. The original appraiser reviews it, and they are under no obligation to change anything.
Realistic expectation: a small fraction of reconsiderations produce a meaningful change, and nearly all of those involved genuinely missed comps or factual errors.
If the ARV stands
Options, roughly in order of preference:
1. Renegotiate the purchase. If you are still under contract with an option period, this is the cleanest fix. A low ARV is information about the deal, not just about the appraisal.
2. Reduce the scope. If some work is not adding proportional value, cut it. That lowers your cost basis and may improve the ratio between cost and value.
3. Bring more cash. Cover the gap between the ARV-capped loan and your total cost.
4. Find a lender with a higher ARV cap. 75% exists, usually for experienced borrowers. A second appraisal with a different lender is also possible — but you pay again and it may come in the same.
5. Walk. If the ARV is materially below your model and you cannot renegotiate, the appraiser may be telling you something true. Losing an option fee and an appraisal fee is far cheaper than a project that loses $30,000.
Estimating ARV yourself, before you offer
Do this before every offer. It takes twenty minutes.
- Pull sold comps, not listings. Asking prices are opinions; closed sales are data.
- Filter to the last six months, half a mile, same school zone.
- Match configuration — beds, baths, square footage within about 15%, similar age.
- Look at the photos. Match your intended finish level to what actually sold at that price.
- Take the conservative end. If comps run $360,000-$410,000, model $370,000, not $400,000.
- Sanity check against the ceiling. Nothing in this neighborhood has ever sold above $420,000? Do not model $445,000.
Model conservatively and verify with your lender before the option period ends. An ARV assumption is the load-bearing number in a flip, and it is the one investors are most optimistic about.
Frequently asked questions
What is ARV? After repair value — the appraiser's opinion of what the property sells for once your scope is completed.
How do lenders determine ARV? An appraiser compares the finished property against recent comparable sales, adjusts for differences, and reconciles to a value. Your rehab spending is not an input.
Why did my ARV come in low? Most often comp scarcity, over-improvement relative to the neighborhood, unpermitted square footage, or unresolved functional obsolescence.
Can I dispute an ARV? Yes, through a reconsideration of value submitted via your lender. Better missed comps and factual errors are the arguments that occasionally work.
Does my rehab budget affect ARV? Only through what the work produces in market value. Spending more does not raise ARV if the market does not pay for it.
What ARV percentage will a lender fund? Typically 65-75%, with the higher end for experienced investors.
How do I estimate ARV before making an offer? Pull closed comps within six months and half a mile, match configuration and finish level, and take the conservative end of the range.
Next steps
Model ARV from closed comps at the conservative end, and confirm it with your lender before the option period closes.
