You get an offer, and buried somewhere in the reasoning is a reference to comparable sales, maybe three, maybe eight, maybe more. The number of comps used can quietly shape how much confidence you should actually place in the resulting figure, yet almost nobody asks how many were actually pulled. Understanding what counts as enough data changes how you evaluate any offer you receive.

Why the Comp Count Actually Matters

A valuation built from three comparable sales carries meaningfully more uncertainty than one built from ten, simply because a small sample is more easily skewed by one unusual transaction, an estate sale priced below market, a bidding war that pushed a price artificially high.

What a Reasonable Minimum Looks Like

Most experienced evaluators aim for at least five to six genuinely comparable sales before feeling confident in a number, ideally within a half mile to a mile radius and sold within the last three to six months, adjusting that radius or timeframe only when local data genuinely requires it.

When Fewer Comps Are Actually Unavoidable

Rural properties, unusual architectural styles, or neighborhoods with very low transaction volume sometimes simply do not have five or six qualifying sales available within a reasonable radius and timeframe, meaning a smaller sample is not a red flag on its own, it is a data limitation worth understanding rather than a sign of a bad evaluation.

What More Comps Do Not Automatically Fix

Pulling fifteen comparable sales does not necessarily produce a better number than six well-chosen ones, if those fifteen include properties that are only loosely comparable, wildly different square footage, meaningfully different condition, or a considerably wider radius than the six more carefully selected sales used instead.

Why This Connects Directly to Offer Percentage

Percentage of market value that cash offers typically reflect depends heavily on how accurately the underlying After Repair Value was actually calculated in the first place, and a weak comparable sales foundation undermines every number built on top of it, regardless of how reasonable the percentage applied afterward might look.

What to Actually Ask Before Trusting a Number

Requesting the specific comparable sales used, and checking how many were pulled, how recent they are, and how close geographically, gives you real information to evaluate an offer’s foundation rather than simply trusting the final figure because it was presented confidently.
