What is a sheriff's certificate?
If you win a foreclosure auction in a redemption state, you do not walk away with a deed. You walk away with a sheriff's certificate of sale, and the distinction is the whole reason those states work differently.
The certificate is a recorded interest that ripens into ownership if — and only if — a statutory period passes without anyone redeeming. Until then you have paid for the property and cannot use it.
What the document actually is#
A sheriff's certificate records five things:
- That a foreclosure sale occurred, on a stated date
- Who bought, and for how much
- The legal description of the property
- The date the redemption period expires
- That title will pass to the holder if nobody redeems
It is recorded at the county recorder or register of deeds like any other interest, and it appears in the chain of title from that point.
What it is not:
| It is not | Because |
|---|---|
| A deed | It conveys no present ownership |
| Possession | The occupant keeps that during redemption |
| Marketable title | Nothing can be conveyed until it ripens |
| Final | Redemption cancels it entirely |
| Insurable, usually | Most insurers will not write over an unexpired certificate |
What you can and cannot do while holding one#
You cannot take possession. The former owner retains the right to occupy the property throughout the redemption period. That is not a courtesy; it is what the period is for.
You cannot renovate. It is not your property. Entering to work on it is trespass, and in some cases worse.
You cannot resell the property. You can assign the certificate, which is a different transaction.
You cannot rent it out.
You can — and in most states should — pay the property taxes and insure your interest. Those advances are typically added to the redemption amount and recovered with interest if the owner redeems, and they protect you against a tax forfeiture running in parallel.
You can assign the certificate. It is a transferable recorded interest and there is an active market in them among investors who want the position rather than the property.
You can watch. That is most of what holding a certificate involves.
How it ends#
Three outcomes.
The owner redeems. They pay the bid plus statutory interest plus your advances. The sale is cancelled, the certificate is discharged, and you receive your money back with interest. Not the property, but not a loss.
A junior lienholder redeems. In many states, after the owner's window closes, junior lienholders get their own staggered periods — a second mortgage, then a third, in order of priority. Each is protecting its position. The practical effect is that the certificate holder cannot assume the property is theirs on the day the owner's period ends.
Nobody redeems. Title vests in the certificate holder. In Minnesota this happens automatically by operation of law when the period expires — no further document from the sheriff, no court order, no new auction. In some other states a sheriff's deed is then issued.
Possession is still separate. Title vesting does not empty the house. If the occupants remain, eviction is a further court process taking weeks or months.
Which states use them#
Broadly, the states with a post-sale redemption period.
| State | Redemption period | Certificate used |
|---|---|---|
| Alabama | Around one year | Yes |
| Iowa | Up to one year, commonly shortened | Yes |
| Kansas | Three months to one year | Yes |
| Michigan | Six months; thirty days if abandoned | Yes |
| Minnesota | Six months; twelve in some cases | Yes |
| Missouri | Mainly where the lender bought | Yes |
| New Mexico | Nine months, often reduced to one | Yes |
| North Dakota | Sixty days | Yes |
| South Dakota | Up to one year, often shortened | Yes |
| Wyoming | Around three months | Yes |
| Illinois | Runs from service or judgment | Certificate of purchase |
| Arizona, California, Oregon, Washington | Judicial foreclosures only | Rarely, in practice |
States with no post-sale redemption issue a deed after confirmation, not a certificate — Texas, Georgia, Virginia, Nevada, Massachusetts, New York and most of the rest.
Verify locally. Whether a certificate is used, what it is called, and how title vests all vary, and several states use different terminology for the same instrument.
Minnesota specifically#
The certificate is central to how Minnesota foreclosure works, and out-of-state buyers misjudge it constantly.
Minnesota forecloses non-judicially — by advertisement — which is fast. Notice published for six weeks, then a sheriff's sale. From default to auction can be a matter of months.
And then grants a full six-month redemption anyway. Twelve months for certain agricultural property and mortgages predating a statutory cutoff, and as little as five weeks where the property has been declared abandoned.
That combination — fast foreclosure, long redemption — is unusual. Most non-judicial states grant nothing after the gavel.
Title vests automatically. When the redemption period expires without redemption, the sheriff's certificate becomes title by operation of law. There is no further instrument to obtain.
The owner keeps possession throughout, and keeps the right to sell. A Minnesota owner in redemption can sell the property to a third party for more than the redemption amount and keep the surplus — which is a live option many owners do not know they have.
How often certificates actually convert#
This is the question that decides whether buying one is worth doing, and it is almost never answered with data because redemption leaves no positive record — only the continued absence of a transfer.
Govire tracks Minnesota redemption windows from the sheriff's sale to resolution using recorded deeds. Across 326 resolved windows:
| Outcome | Share |
|---|---|
| Owner redeemed — the certificate was discharged | 33.4% |
| Certificate converted, or the property was resold | 66.6% |
A third of certificates do not become property. The holder receives their money back with statutory interest, which is a return, but it is not the asset they bid for.
And the distribution is exactly wrong for a buyer hunting bargains:
| Winning bid vs assessed value | Owner redeemed | n |
|---|---|---|
| Under 50% | 58.1% | 31 |
| 50–80% | 44.2% | 77 |
| 80% or more | 20.0% | 50 |
A certificate bought at under half the assessed value was redeemed more than half the time. The mechanism is straightforward — an owner with real equity has something worth saving and something to borrow against.
Whether the owner lives there matters too: 38.6% redeemed on homesteaded property against 24.6% on non-homesteaded, across 171 and 114 windows. Homestead status is on the county assessor record, so this is knowable before the sale.
And the wait is longer than the statute#
Across 1,336 tracked Minnesota windows:
| Time from sale | Reached a foreclosure sale |
|---|---|
| 6 months | 3.2% |
| 1 year | 33.0% |
| 18 months | 51.0% |
Half of all windows were still unresolved at eighteen months, against a six-month statutory period. Postponements, bankruptcy filings and loss mitigation all extend it. Capital committed to a certificate sits far longer than the rules imply.
Buying and selling certificates#
An assignable recorded interest creates a market, and it is a different business from buying property.
Why someone sells. The holder wants their capital back before the period expires, has decided they do not want the property after all, or is a lender that would rather have cash than an asset.
Why someone buys. They want the position — either the statutory interest if it redeems, or the property if it does not. A certificate on a property with little equity is close to a fixed-income instrument, because redemption is unlikely and conversion is the expected outcome.
What to check before taking an assignment:
- The exact expiry date, from the certificate itself
- What has been advanced — taxes, insurance — since these add to the redemption amount
- What other liens exist, and whether junior lienholders have their own redemption rights coming
- Whether a bankruptcy has been filed, which stays everything
- Whether the property is occupied, and by whom
- Whether the assignment is recorded, because an unrecorded one is a problem waiting
The assignment must be recorded. An unrecorded assignment leaves the record showing the original holder, which creates exactly the kind of title question that stops a later sale.
Insuring and financing a certificate#
Two practical problems that stop certificate purchases from behaving like property purchases.
Title insurance is generally unavailable while the period runs. Most insurers will not write a policy over an unexpired certificate, because the interest is contingent by definition. That means no conventional financing on the property, no clean resale, and no way to give a buyer comfort until the window closes.
Some insurers will write after expiry without further action, particularly in states like Minnesota where title vests automatically and the statutory notice requirements are substantial. Others want a quiet title action first, especially where notice to a party was arguably defective. Ask a local title company before bidding, because the answer determines whether your exit is weeks or months after expiry.
Insure your interest, not the building. You do not own the property, so a standard owner's policy is wrong. What you can protect is your position — and paying the hazard premium on a vacant property you hold a certificate over is usually recoverable as an advance if the owner redeems.
Financing is limited to lenders who understand the instrument. A national hard money lender that has only worked in non-redemption states may not know that a sheriff's certificate is not a deed, and that surfaces at closing when their template asks for title they cannot get. Ask directly whether the lender has funded a certificate purchase in your state.
Property taxes during the redemption period#
This is the trap that costs certificate holders real money, and it comes from two clocks running at once.
The owner is unlikely to pay the taxes. Someone who has already lost the property at a foreclosure sale has little reason to keep paying tax on it, and often no ability to.
Unpaid tax runs its own forfeiture clock, entirely separate from the redemption period. In Minnesota that clock is three to five years from a tax judgment, so it will not usually mature inside a six-month redemption — but on a property already carrying two or three years of delinquency, it can.
So the certificate holder should normally pay the taxes. The advance is typically added to the redemption amount and recovered with interest if the owner redeems, and it prevents the worst outcome: waiting out a six-month redemption on a parcel that then forfeits for tax anyway.
Check the tax position before bidding, not after. The county treasurer will tell you what is outstanding. A property with several years of delinquency and a foreclosure sale on the same day is a property with two problems, and the auction price should reflect both.
The three ways certificate holders lose money#
Not principal, usually. Return and time.
Redemption at the statutory rate when you wanted the property. You planned a renovation and got a fixed-income outcome instead. In Minnesota that happens a third of the time overall and more than half the time on deep discounts.
Advances that are not recovered. Taxes and insurance paid on a property that then redeems are usually recoverable — but only if properly documented and claimed. A holder who pays a tax bill and does not record it with the sheriff or the county can find the redemption calculated without it.
Holding cost on capital that sits. Half of Minnesota windows are unresolved at eighteen months against a six-month statutory period. Money committed at a sheriff's sale on the assumption of a six-month turn, still committed at month twenty, has cost whatever it would have earned elsewhere — and that opportunity cost does not appear on any statement.
What it means practically#
If you are bidding at a sheriff's sale in a redemption state, you are not buying a house. You are buying a contingent claim with a waiting period, and roughly a third of the time in Minnesota you get your money back instead of a property.
Price the wait. Six months of statutory period is a floor, half of windows run past eighteen months, and capital is unavailable throughout.
And notice the inversion. The properties that look like the best deals — the deepest discounts to assessed value — are the ones most likely to be redeemed out from under you. The certificate was never the bargain it appeared to be; it was priced correctly for the risk that you would not keep it.
If the property is yours and someone holds a certificate on it, the redemption period is your window and nobody else's. You keep possession, you keep the right to sell, and if the property is worth more than the redemption amount, the difference is yours if you act inside the window and nobody's if you do not.
