Why It Matters
Flip comps tell you what your finished flip should sell for. You find recently sold, renovated homes nearby that match your subject property's size, style, and bedroom count, then use those sales to set your ARV. That ARV drives your maximum purchase price and your renovation budget.
At a Glance
- Flip comps are sold — not listed — prices of renovated comparable homes
- They differ from standard comps because the condition must match the post-renovation finish level
- The standard search window is sales within 0.5–1 mile and within the last 90–180 days
- A strong ARV requires at least 3 solid comparable sales
- Overestimating ARV is one of the most common causes of failed flips
How It Works
Pulling flip comps starts with defining your subject property's finished state. Before you can compare, you need to know what the property will look like after renovation — square footage, bedroom and bathroom count, garage, lot size, and the quality of finishes you plan to install. That finish level matters enormously: a flip with countertops from a builder-grade laminate line will not comp against a kitchen featuring quartz and custom cabinetry.
Once you know your finished product, you search the MLS (or a data source like Redfin, Zillow, or PropStream) for sold homes — not active listings — within roughly half a mile to one mile of your property, sold within the past 90 to 180 days. You filter for similar square footage (typically within 10–15%), the same bedroom and bathroom count, and comparable lot size and garage configuration.
The condition filter is where flip comps diverge from standard purchase comps. You are not looking for all similar sold homes — you are specifically looking for renovated homes. A dated original home that sold for $210,000 is not a flip comp for a property you plan to sell fully remodeled at $310,000. You want homes that went through some level of renovation: new kitchen, updated baths, fresh flooring, and updated systems.
After collecting your candidate comps, you adjust for differences. A comp with an extra half-bath gets a downward adjustment on your subject. A comp with a larger lot or a finished basement gets a downward adjustment if yours lacks those features. Most residential investors use a simplified dollar-per-square-foot approach rather than appraiser-level adjustments, but the goal is the same: arrive at a realistic price per square foot for your finished product and apply it to your subject property's square footage.
With three or more adjusted comps in hand, you bracket your ARV — usually taking a conservative figure rather than the ceiling. That ARV then feeds the 70% rule or your custom MAO (maximum allowable offer) formula to produce your top purchase price.
Real-World Example
Raj is analyzing a three-bedroom, one-bath ranch in need of a full gut renovation. The home has no working kitchen, a damaged subfloor exposed during a demo day walkthrough, cracked drywall throughout, and framing issues in one exterior wall. He estimates $75,000 in repairs.
To set his ARV, Raj pulls flip comps within 0.8 miles. He finds four sold homes in the past five months: a three-bed, one-bath at 1,100 sq ft that sold for $289,000 after full renovation; a three-bed, one-bath at 1,050 sq ft that sold for $278,000 with a remodeled kitchen and new flooring; a three-bed, two-bath at 1,200 sq ft that sold for $315,000 (he adjusts down for the extra bath his subject lacks); and a two-bed, one-bath at 950 sq ft that sold for $255,000 (too small — he excludes it).
Using the three comparable sales, Raj calculates an average of roughly $266 per square foot on his 1,080 sq ft subject — landing at an ARV of $287,000. He rounds conservatively to $280,000. Applying the 70% rule: $280,000 × 0.70 = $196,000, minus $75,000 in repairs = a maximum offer of $121,000. Raj submits at $115,000, leaving himself a cushion.
Pros & Cons
- Anchors the entire deal to real market data rather than gut instinct
- Prevents overpaying for a property based on wishful pricing
- Helps investors size renovation budgets to what the market will actually reward
- Builds credibility with lenders and hard money providers who need to see ARV support
- Forces investors to research the neighborhood before committing capital
- Renovated comps can be hard to find in slower markets or rural areas with low transaction volume
- Condition assessments on sold homes are often incomplete — you cannot always confirm finish quality from photos alone
- MLS data may lag the market, making comps from six months ago less reliable in fast-moving conditions
- Small sample sizes (fewer than three comps) produce unreliable ARV estimates
Watch Out
The biggest trap is cherry-picking the highest sold price in the area and calling it your ARV. Flip comps must reflect the realistic finish level you are actually delivering. If your renovation plan includes builder-grade countertops and standard-grade flooring, you cannot comp against a luxury flip with high-end finishes. One mismatch can put your ARV $20,000–$40,000 too high and erase your entire profit margin.
Also watch out for listing prices. Active listings are not comps. The market pays what it pays — always use sold data, and be skeptical of pending sales where final prices are not yet confirmed.
The Takeaway
Flip comps are the foundation of every sound house flip decision. Get them right and your entire deal analysis — offer price, renovation budget, profit projection — rests on solid ground. Get them wrong and you may buy a property at a price that makes profit mathematically impossible before the first nail is pulled. Pull at least three renovated, sold comparables, adjust carefully, and use a conservative ARV. The deal either pencils at that number or it does not.
