Flip Detector — Boulder, CO
Property flips in Boulder, CO — bought and resold within 24 months for 20%+ profit.
Public Record
What is a flip?
What we count as a flip
A property bought and resold within 24 months, where the second sale price was at least 20% higher than the buy price. That gap usually pays for renovation, holding costs, and investor profit.
How we found these
We compare consecutive deed transfers from public county records. When the same property changes hands twice in a short window with a meaningful price jump, we tag it as a flip.
What you can use this for
Spot neighborhoods where investors are buying and reselling, gauge typical profit margins in your market, and benchmark your own deals against real, completed transactions.

How to interpret these numbers
What a high gain % means
A 200%+ jump can be a real flip with serious renovation, but it can also be a major addition (extra bedroom, full gut), an off-market family transfer recorded at $1, or a data-entry quirk. Use it as a signal — not a verdict.
Why hold period matters
Institutional buy-and-hold investors typically resell in 6–18 months. Individual fix-and-flip operators usually move faster — 3–9 months. A market full of 3-month holds suggests aggressive flipper activity; longer holds often mean rental conversions or speculative buyers.
Where this data comes from
Every transaction shown is sourced from county deed records — the same public filings used by title companies and assessors. We aggregate them nightly and only count consecutive sales of the same parcel. Source: public record.
