Why Condition Is the Adjustment Most Investors Skip
Most investors pull comps the same way: same bed and bath count, square footage within 10 to 15 percent, sold in the last six months, close by. That filter feels rigorous, but it ignores the variable that often moves price the most on a flip. Two 3/2 ranches on the same street can sell for $255,000 and $330,000, and that $75,000 gap usually comes down to what the buyer walked into. Average those two sales and you get $292,500, a number that matches neither house.

ARV means the value of the property after your rehab, not after some imagined gut job. Every comp you rely on has to reflect the finish level you will actually deliver. If your budget covers paint, LVP flooring, and new fixtures, your comps should be cosmetic flips. A full renovation with a reworked layout and new systems is the wrong benchmark for that scope.
A simple four-tier scale keeps your grading consistent:
- Dated original: Original kitchen and baths, older roof and HVAC, often sold as-is or to another investor.
- Partial update: One or two rooms refreshed, such as new carpet or a redone hall bath, with the rest left original.
- Cosmetic flip: Kitchen and baths updated with new surfaces and fixtures, fresh paint and flooring throughout, but the roof and HVAC are left alone.
- Full renovation: Kitchen, baths, roof, and HVAC all replaced, usually with permits pulled for the mechanical work.
Four sources of evidence place a comp in its tier. Listing photos show cabinet style, countertops, and tile. MLS remarks often spell out details like "new roof 2023" or "sold as-is, cash only." The county permit portal confirms whether reroofing, HVAC replacement, or electrical work was actually done. Then run the four-item check: kitchen, baths, roof, HVAC. Count how many were touched, and the tier usually becomes obvious.
Grade every comp before you adjust for size or bedroom count. Size adjustments applied to comps from the wrong tier only make a wrong number look precise.
Worked Example: Grading Five Comps on a 1,450 Sq Ft 3/2
Say your subject is a 1,450 sq ft 3/2 that you plan to fully renovate with mid-grade finishes and a $55K budget. You pull five sales within 0.5 miles, all between 1,420 and 1,500 sq ft. Size is close enough that condition becomes the variable that moves the number. Here is what the listing photos and descriptions reveal:
- Comp A: $312K, 1,480 sq ft, full renovation
- Comp B: $298K, 1,420 sq ft, cosmetic flip (paint, floors, original HVAC)
- Comp C: $245K, 1,500 sq ft, dated original
- Comp D: $335K, 1,460 sq ft, full renovation with premium finishes
- Comp E: $271K, 1,440 sq ft, partial update
The naive average is ($312K + $298K + $245K + $335K + $271K) / 5 = $292.2K. That number blends a fixer with a luxury flip, so it describes no real house. The opposite mistake is just as common. An investor who wants the deal to work keeps only the two renovated sales, A and D, and gets ($312K + $335K) / 2 = $323.5K.
A condition-matched ARV grades each comp against your finished product. A matches your scope, so it stays at $312K. B gets about $6K added because your rehab includes a new HVAC system, bringing it to $304K. E needs roughly $32K added to bring its partial update up to full renovation, landing at $303K. D comes down about $30K for quartz, custom tile, and upgraded fixtures you are not installing, giving $305K. C is too far from your finished condition to adjust credibly, so you discard it. The average of the four is ($312K + $304K + $303K + $305K) / 4 = $306K, and you round down to a conservative $305K.
Now run the 70% rule. At $305K, MAO is ($305K x 0.70) minus $55K, which equals $213.5K minus $55K, or $158.5K. At the cherry-picked $323.5K, MAO becomes $226.45K minus $55K, or $171.45K. That gap means you would offer about $13K more than the deal supports, before a single contractor surprise eats into what is left.
Worked Example: Matching Your Rehab Scope to the Comp Tier
Take the same 1,450 sq ft 3/2 from the comp grid above. You now have two defensible paths, and each one has its own ARV. A $38K cosmetic scope (paint, LVP flooring, new fixtures, refaced kitchen cabinets, updated lighting) puts the house in line with the cosmetic-flip tier, which supports a $298K ARV. A $62K full renovation (new kitchen layout, gutted baths, updated electrical panel, new windows) lines it up with the full-reno tier at $312K.
Run the 70% rule on each path, using the ARV that its own comps support. The cosmetic path works out to ($298,000 x 0.70) - $38,000 = $208,600 - $38,000 = $170,600 MAO. The full renovation works out to ($312,000 x 0.70) - $62,000 = $218,400 - $62,000 = $156,400 MAO. The cheaper scope lets you offer $14,200 more for the same house and still hit your margin.
The reason is simple. The full reno costs $24K more but raises ARV by only $14K, so you spend $24K to gain $14K of value. Many investors miss this because they pair the big scope with the cosmetic tier's comp count, or pair the cosmetic scope with the full-reno ARV. Either mismatch makes the deal look better on paper than it will at closing. The rule is to price each scope only against comps that finished at that same level.
FlipSmrt keeps those two numbers tied together. It pulls adjusted MLS sold comps within 0.5 miles and builds line-item rehab costs by trade, priced for the property's county, so the renovation you are pricing matches the condition of the comps behind your ARV. You can compare a cosmetic scope and a full-reno scope on the same address without rebuilding a spreadsheet for each one.
For your own deals, write down both scopes, pull the ARV each tier supports, and compare the MAOs. If the extra rehab dollars do not come back as at least that much added ARV, the lighter scope usually wins.

Analyze a Property FreeEdge Cases: No Flips Sold, Missing Photos, and Mixed-Condition Streets
Sometimes the 0.5-mile radius has no renovated sales in the last six months. Don't stretch the search to two miles just to find a flip, because you trade a condition problem for a location problem. Instead, step down a tier: use the updated or dated sales that do exist and add a documented condition adjustment. Write down where that number came from, because an adjustment you can't source is just optimism.
The cleanest source is a paired sale. Find two similar homes in the same subdivision that sold within a year of each other, one renovated and one original. If a flipped 1,400 sq ft 3/2 closed at $312,000 and a dated 1,420 sq ft 3/2 closed at $274,000, the condition gap is roughly $38,000. Add that to your dated comps and your ARV rests on actual market behavior.
Comps that sold with no interior photos are common with investor and off-market sales. Read the agent remarks for phrases like "needs TLC," "cash only," or "new roof and HVAC," which usually signal condition. Pull county permit records to see whether kitchen, electrical, or plumbing permits closed before the sale. Then search the address for photos from a prior listing, since many homes were photographed during an earlier sale or an expired listing.
Watch for new-construction infill on an older block. A 2023-built 2,100 sq ft house selling at $420,000 next to 1950s ranches is not a renovated comp, even if your rehab is thorough. It has new framing, a modern layout, builder warranties, and usually more square footage. Exclude it, or treat it as a ceiling your flip won't reach.
Your end buyer's appraiser will grade these same comps, typically on the C1 to C6 condition scale, and the lender will review that report. If you call a C4 sale "flipped" to justify a higher ARV, the appraisal will likely come in low and your buyer will ask for a price cut. Grade comps the way an appraiser would, and your ARV should hold up under a lender's review.
Condition-Grading Mistakes That Inflate ARV
The most common error is reading "updated" in the MLS remarks as "fully renovated." Agents use that word for everything from fresh paint to a complete gut, so a house with new carpet and a 2005 kitchen can carry the same label as a true flip. Quick check: open the photos and confirm the kitchen, baths, and flooring are all new. If you can't verify all three, grade the comp one tier lower.
The second mistake is using a premium-finish flip to justify a builder-grade budget. Say a comp sold for $345,000 with quartz counters, tiled walk-in showers, and designer lighting, but your $45,000 rehab buys laminate counters and fiberglass tub surrounds. Buyers notice that gap, and so do appraisers. Quick check: compare the comp's finishes to your scope line by line. If your materials are a step down, pull your ARV toward the next tier rather than the top sale.
Third, investors average dated and renovated sales together. Four sales at $255,000, $260,000, $335,000, and $342,000 average out to $298,000 ($1,192,000 divided by 4), a price no house on that street actually sold for. That blended number overstates a light cosmetic job and understates a full renovation. Quick check: sort comps into condition tiers first, then average only the tier that matches your finished product.
Fourth, many investors ignore big-ticket systems. A flip with shiny finishes but a 22-year-old roof, an original HVAC unit, and a 100-amp panel often closes lower after inspection credits, while a comp with all new systems sets a higher bar. Quick check: scan the remarks or call the listing agent to find out the age of the roof, HVAC, and electrical. Then either add those items to your rehab or adjust your ARV down.
The last mistake is double-counting condition. If you hand-pick only the best-looking comps and then also apply an upward condition adjustment, you've given your subject the same credit twice. Quick check: choose one method. Either pull a mixed-condition set and adjust each comp, or use only same-tier comps with zero condition adjustment. Never do both.
FAQ: Comp Condition and ARV
How big should a condition adjustment be, and how do you support it? There is no universal percentage, so build the number from paired sales in your own submarket. Find two sales on similar streets with matching size, beds, baths, and age, where the main difference is condition. If a flipped 1,400 sq ft 3/2 sold for $312,000 and a dated one nearby sold for $268,000, that $44,000 gap is your evidence. Two or three pairs that land in a similar range give you an adjustment you can defend to a lender.
Can a comp be off-tier and still usable? Yes, as long as you adjust it and weight it lightly. A "partially updated" sale can still anchor your ARV if you add a supported condition adjustment and the rest of the match is tight. Treat off-tier comps as supporting evidence, not your primary number. If most of your comps need large condition adjustments, widen your search before trusting the result.
Should flips by other investors count as comps? They are often your best comps, because they show what renovated product actually sells for on that block. Check the listing photos and description to confirm the finish level matches your planned scope. A flip with quartz, new HVAC, and a reconfigured layout is not a fair comp for a paint-and-flooring job.
How do you grade a comp with no photos? Look for indirect signals instead of guessing. Check the prior sale history, days on market, the listing remarks ("needs TLC" versus "fully renovated"), and permit records for recent kitchen, roof, or mechanical work. If you still cannot place it with confidence, grade it conservatively or drop it from the set.
