Frequently asked questions
What does over-the-counter mean in Douglas County?
When a Douglas County tax-lien certificate gets no bid at the tax sale, the county keeps it and later sells or assigns it to a buyer who applies, with no auction. You buy the certificate, not the property, and the owner can still redeem; the price rules differ by state.
How do I buy an OTC property in Douglas County?
Douglas County publishes its held/available list and an application process — typically a form plus payment of the taxes and fees. DeedFlex members see the scored Douglas County OTC list with valuations and hidden-lien flags to pick targets before applying.
Are Douglas County OTC properties cheaper than auction?
A certificate's over-the-counter price is what is owed on it, so there is no bidding premium. The tradeoff is the inventory skews toward what bidders passed on, so research the parcel as if you might end up owning it.
