Maryland

What Maryland actually sells

Every Maryland county, plus Baltimore City, holds its own annual tax sale under Title 14, Subtitle 8, Part III of the Tax-Property Article. When an owner falls behind, the collector sells a certificate of sale against the property, not the property itself. You are advancing the delinquent taxes, interest and costs on the county's behalf, and you get a lien in return.

That certificate does not make you the owner. Maryland gives the original owner a redemption period after the sale, and most certificates are redeemed — the owner, a mortgage company, or an heir pays off the debt and you are repaid with interest. Only a minority of certificates ever reach the deed stage described further down.

How the bidding actually works: price, not rate

This is the detail that trips up out-of-state investors. In Maryland, the interest rate paid on redemption is fixed by statute or local law before the sale — it is not auctioned. What you bid on is the price of the certificate, at public auction to whoever makes the highest good-faith accepted bid (§ 14-817(a)–(b)).

The minimum bid can never be less than the total taxes, interest, penalties and sale expenses owed on the property (§ 14-817(d)) — that lien passes straight through to the buyer. Above that floor, several of the larger counties (including Baltimore City, Baltimore County, Montgomery County and Prince George's County) charge a high-bid premium: 20% of the amount by which the winning bid exceeds 40% of the property's full cash value (§ 14-817).

The premium is not free money for the county to keep. It is refunded to you, without interest, when the property is redeemed or when you receive the tax sale deed. If neither happens before the deadline to foreclose the right of redemption passes, the premium is forfeited. Bidding a large premium to win a certificate you never follow through on is how that money disappears.

The interest rate: fixed by county, not by auction

Under § 14-820, the statewide default redemption rate is 6% a year, but the statute lets each county set its own rate by local law, and several do: Carroll County charges 14%, while Calvert, Caroline, Dorchester and Garrett counties charge 10%. Baltimore City sets its own rate by city ordinance — for the 2026 sale that is 18% on non-owner-occupied property and 10% on owner-occupied residential property.

Whatever the county sets, § 14-820(b) caps the rate on owner-occupied residential property at 10% a year statewide. A county cannot charge a homeowner more than that to get their house back, no matter what its ordinary rate is. The collector is required to print the applicable rate on the certificate of sale itself, so check the certificate, not a general guide, before you assume a number.

Interest accrues from the date you paid to the date of redemption. It applies to the taxes and costs you advanced — not to the high-bid premium, which comes back flat.

Redemption: how long you actually wait

A property owner can redeem at any time up until the court forecloses the right of redemption — there is no fixed "last day" set at the sale. What is fixed is how soon you, as certificate holder, are allowed to start that foreclosure process.

Under § 14-833(a), you may not file a complaint to foreclose the right of redemption until 6 months have passed from the date of sale for ordinary property, or 9 months for owner-occupied residential property. Before you can even file, you must send two separate notices to the owner and any mortgage holder: the first no earlier than 4 months after the sale (7 months for owner-occupied property), the second at least 30 days before filing, with at least 2 months between the first notice and the filing itself.

Skip or botch either notice and the case gets dismissed regardless of how much time has passed — Maryland courts treat the notice requirements as jurisdictional, not a formality.

The two-year deadline

Maryland certificates do not sit valid forever while you wait for a good moment. Under § 14-833(c), a certificate of sale is void unless a proceeding to foreclose the right of redemption is filed within 2 years of the date of the certificate. Miss that window — whether from inattention or because you were waiting for the property to become "worth it" — and the money you advanced is simply gone, with no property and no refund of the premium.

Given that the minimum wait before filing is 6–9 months and two rounds of notice have to be sent and to clear before filing, the real usable window is closer to a year than two. Investors who treat the two-year figure as slack tend to run out of time.

What happens when nobody bids

Not every certificate finds a buyer at auction, particularly on marginal or landlocked parcels. County tax sale terms across Maryland — Baltimore County's and Anne Arundel County's published collector's terms both confirm this — state that when a property draws no bid, the county itself becomes the purchaser, holding the certificate the way a private bidder otherwise would.

Unlike Florida's county-held certificates, which sit at the statutory maximum rate and can be picked up over the counter, Maryland counties do not run a standard public resale channel for these; practice varies by county, so check with the specific county finance office rather than assuming a process exists.

Getting to the deed, and what you actually get

If redemption never happens and your foreclosure case succeeds, the court's judgment — not a deed you record yourself — is what transfers ownership. Under § 14-844, the judgment vests an absolute and indefeasible title in fee simple in you, free of the liens and interests that existed before judgment, with narrow exceptions for taxes accruing after judgment and certain recorded easements.

One exception matters if you are not watching for it: if the property was subject to a ground rent and the ground rent holder was not made a party to your case, you receive only a leasehold interest, not fee simple — Maryland is one of the last states where ground rents are still common, concentrated in and around Baltimore.

From the day of judgment you are responsible for ongoing property taxes and, if applicable, HOA or condo assessments. In Baltimore City specifically, the judgment for an owner-occupied property must state whether a bid balance is owed to the former owner and explain how they claim it through the Bureau of Revenue Collections — that surplus is the former owner's, not yours.

Where the lists are published

Each collector advertises the list of property to be sold under § 14-813: the property address, the owner of record per the tax roll, taxes owed, and assessed value. Most counties publish this 4 times over 4 successive weeks in a newspaper of general circulation; Dorchester, Frederick, Garrett, Kent and Queen Anne's counties publish 3 times over 3 weeks, and Baltimore City publishes twice in alternate weeks plus posts the list on the city's own website starting 4 weeks before the sale.

Because the format and timing differ county by county, always pull the list from that county's tax collector or finance office directly for the year you intend to bid, rather than from a prior year's schedule or a generic aggregator.

Five ways people lose money here

1. 1. Expecting to bid the rate down

   Maryland fixes the redemption rate by statute or local law before the sale (§ 14-820). The auction bids up the price, not down the rate — bringing a Florida or Arizona bidding strategy here means overpaying for a rate you can't change.

2. 2. Assuming the high-bid premium earns interest

   It doesn't. The premium is refunded flat on redemption or deed, and forfeited entirely if you never foreclose or the property never redeems before the deadline. It is capital at risk, not part of your yield.

3. 3. Filing to foreclose before the notice clock has run

   Two separate notices are required, with minimum gaps between the sale, the first notice, the second notice and the filing itself (§ 14-833(a), (a-1)). A complaint filed too early is dismissed regardless of how strong the underlying debt is.

4. 4. Treating the two-year window as two years of usable time

   The 6–9 month minimum wait plus mandatory notice periods eat most of it. Certificates that sit untouched become void under § 14-833(c) — the deadline runs from the certificate date, not from when you get around to it.

5. 5. Ignoring an unresolved ground rent

   If the property carries a ground rent and its holder isn't joined to the foreclosure case, § 14-844 gives you a leasehold, not the fee simple title you expected. Ground rents are still active across large parts of Baltimore City and County.
