Flip Detector — Boulder, CO
Property flips in Boulder, CO — bought and resold within 24 months for 20%+ profit.
What is 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.
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.
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
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.
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.
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.
