Franklin County, Ohio has about 698 active investors. Collin County, Texas has about 3,378. If you are picking a market on investor count, Collin wins by almost five to one and the decision looks obvious.
Now the other number. Those 698 Franklin County investors hold roughly 58,300 properties between them. The 3,378 in Collin hold about 63,100. Nearly the same pile of real estate, split very differently.
That works out to about 84 properties per active investor in Franklin County, and about 19 in Collin. Same asset class, same rough market size, and one has buyers who are four times larger.
Franklin County averages about 84 properties per active investor; Denver County about 9.
Neither number is better. But they are not the same business, and the buyer list you should build in each is close to the opposite of the other.
What a concentrated market actually feels like
Start with Franklin County, because it is the clearer case.
Fewer, bigger buyers means the serious money sits with a small group. Eighty-four properties is not somebody with a rental and a side hustle. That is an operation: a repeatable acquisition process, financing lined up, probably crews on retainer.
For a wholesaler, three things follow.
The list is learnable. Several hundred active buyers sounds like a lot until you compare it to the alternative. You can work through the top forty in a county like this and genuinely know them — what they buy, what they refuse, who actually answers the phone. That is a few weeks of deliberate work, not an impossible research project, and at the end of it you are not guessing about the people who matter most in your market.
One relationship is worth more. If a buyer holds eighty-plus properties and keeps buying, they are not a one-deal contact. Get into their flow and you have a repeat outlet, not a transaction.
But rejection costs more too. When twenty buyers represent most of the real demand, burning one is a real loss. You do not get to spray a concentrated market and hope. The same discipline that makes the list learnable makes carelessness expensive.
What a fragmented market feels like
Collin County is the other shape. Thousands of active investors, nineteen properties each on average.
Many of those buyers are small — a few houses, maybe a dozen. They are active, they are real, but no single one of them is a significant share of the market.
That changes the job.
Reach matters more than depth. No relationship carries the market, so you need volume in your list. The buyer who takes this deal may not want the next one, and that is fine.
Speed matters more. In a fragmented market you are rarely the only person who has found a buyer. You are competing on who gets there first with something clean.
Qualification matters more. With thousands of names, the limiting factor is not finding buyers, it is sorting them. Most of your effort goes into working out which of these people actually buys what you have.
Here is the trap: a fragmented market looks better on a dashboard. More investors, more activity, more names to collect. It is also the market where a long unqualified list is least useful, because the names are plentiful and the matching is the hard part.
Why the average hides as much as it shows
One honest caveat, because this number can be read too hard.
Properties per investor is an average, and averages flatten things. A county at 84 might have twenty institutional holders with hundreds each and a long tail of people with two. The average does not tell you the shape of that distribution, only its center.
What it reliably tells you is the scale you are dealing with. A market averaging under twenty is one where most buyers are small operators, whatever the tail looks like. A market averaging over eighty has serious institutional weight in it somewhere. That is enough to change how you build a list, which is what you needed it for.
It also says nothing about whether those investors are still buying. A market can be concentrated and dormant at the same time — a few large holders sitting on property they bought years ago. Concentration tells you the shape of demand, not whether demand is awake. For that you need the pace numbers, which are a separate check.
Reading your own market
The calculation is simple: investor-owned properties divided by active investors.
Across the counties in our coverage, the spread is wide. Franklin County sits near 84. Mecklenburg County, North Carolina is around 32. Collin County is about 19. Denver County, Colorado is near 9 — a market of many small holders.
A useful way to hold it:
Under about 20 — fragmented. Build wide, qualify hard, move fast. Your advantage comes from coverage and speed, not from relationships.
Around 20 to 40 — mixed. There is a serious core worth knowing by name, with a long tail behind it. Most markets live here.
Over about 60 — concentrated. Build a short, deep list. Learn the top operators properly, because they are most of the demand and there are not many of them.
Where this changes a decision
The practical version: before you build a buyer list in a new market, work out which shape it is, because the two lists look nothing alike.
In a concentrated market, a list of four hundred names is mostly noise. The forty that matter are buried in it, and the work is identifying them, not collecting more.
In a fragmented market, a list of forty is too thin. You will burn through it on a property that does not fit and have nowhere to go.
Most advice about buyer lists assumes one shape and never says which. "Build a list of cash buyers" is reasonable guidance in Collin County and actively unhelpful in Franklin County, where what you want is a short list of the right people and a reason for them to take your call.
Check the shape before you start building. It takes one division, and it tells you what kind of work the next month should be.
