The opening bid at a trustee sale already reflects someone else's math, and most buyers do not ask whose.

The framework is solid. The part worth pressure-testing is the comp selection, because the gap between the distressed comp and the retail comp is where most auction underwriters quietly, sorry, where most auction underwriters get the number wrong.

The distressed comp is doing the most work in your math, and it is usually the thinnest data set in the county. If there are two REO sales in the submarket over the past six months, you are building an impaired-value estimate on two data points, both of which may have had different tenant situations, different deferred maintenance profiles, and different buyer pools. The retail comp is abundant and reliable. The impaired-value discount you apply to get from retail to distressed is where the assumption lives, and that discount is often borrowed from a neighboring market or a prior cycle rather than derived from current local evidence.

The other risk the post does not name is the senior lien problem. An opening bid set at the defaulting loan balance tells you nothing about what sits ahead of it. Property tax arrears, HOA liens in super-lien states, and prior recorded encumbrances can survive the trustee sale depending on lien priority and state law. A licensed title professional needs to confirm the lien stack before the bid, not after. That is not a step to approximate.

Your point about pulling the published opening bid before the auction date is correct, and it is underused. Running that comparison cold, against both a distressed comp and a full carrying-cost model including holding, rehab contingency, and disposition costs, is the only way to know whether the floor is already above your walk-away number before you park the car.

What source are you using to pull the opening bids, and how far out are they published in your target county?

This is a genuinely useful frame for anyone trying to understand why auction crowds can look confident while chasing a losing position.

One thing worth defining for anyone new to this thread: a trustee sale is the public auction that happens after a borrower defaults and the statutory waiting period expires. The opening bid is set by the lender, typically the unpaid loan balance plus attorney fees and accrued costs. It is not an appraisal. It is an accounting figure.

The distinction the original post draws matters a lot in practice. If a home was purchased in 2021 with a large loan and values in that zip code have since fallen, the opening bid can sit above what any buyer with a mortgage would pay today. The lender knows this. They are not offering a deal; they are satisfying a legal requirement. The property goes back to them as REO (real-estate-owned, meaning bank-owned after the auction fails to attract a bid above the floor), and they handle it separately.

The piece worth adding for a beginner: the opening bid is public record in most states before auction day, filed with the trustee or posted on the county recorder's site. You can look it up, pull a distressed comparable sale (a comp, meaning a recent sale of a similar property in similar condition), and do the arithmetic without pressure, before you are standing in a parking lot with a cashier's check.

The post is right that repair unknowns are the variable that collapses thin margins fastest. A 20 percent discount against a clean retail comp can disappear entirely once a bad roof, deferred maintenance, and an occupied-tenant situation are priced in honestly.

Have you pulled an opening bid yet, or is the mechanics of finding those filings in your county the sticking point right now?

The published-bid-versus-distressed-comp gap is real, but in Georgia it hits different because we run non-judicial foreclosures on a four-week notice period and the sale happens on the first Tuesday of the month at the courthouse steps, which means you have a hard deadline to work backward from and not much room to drag your feet pulling comps. I started pulling the published notices out of the legal organ for my county about eight months ago and running them against actual distressed sales, not Zestimates, and about 60 percent of the time the opening bid is sitting above where a cash buyer would close after repairs. Those properties are going back to the bank. The other 40 percent, the lender's math is stale enough that there's room, but you still don't know the roof, the HVAC, or whether somebody's cousin is living in the back bedroom under a month-to-month that predates the foreclosure.

The part about the tenant knowing their rights is where I'd push back on framing this as a 30 to 40 percent haircut being survivable. In Georgia, post-foreclosure eviction timelines on a tenant with any kind of written lease can stretch 60 to 90 days easy, and if they've been paying rent to the borrower while the foreclosure was grinding along they have standing to make your life expensive. That eats into a thin margin faster than a bad roof does. What county are you working in, because the volume of sales on the first Tuesday swings wildly and that changes how much competition you're actually pricing against at the steps?

Garfield Heights had a trustee sale last March where the opening bid was $112k on a property that sold REO four months later for $89k.

Confirm the postponement history on that specific trustee file before you pull any comp.

The tenant-in-possession risk you flagged deserves a number attached to it: an occupied property in a state with strong tenant protections can add four to nine months of carrying costs before you have possession, and that alone can erase the spread between the opening bid and a distressed comp. Confirm current eviction timelines for your specific county with a local unlawful detainer attorney before you bid.

The opening bid being a published record is the part most newcomers treat as a footnote, but it is actually the only hard number you can work with before the auction, and the comparison that matters is not to the retail comparable but to what a cash investor would pay for the property in its probable condition, which is a different figure and usually 15 to 25 percent lower depending on asset class and deferred maintenance assumptions.

The assumption doing the most work in the original post is that the impaired value is knowable before you go inside, and I want to push on that. You can get close by triangulating: pull the last arms-length sale, subtract a condition haircut derived from the neighborhood's distressed comp spread, then subtract your required return on an all-cash basis since you have no financing contingency. If the published opening bid still sits below that number, you have a real floor. If it sits above it, the lender has already priced you out and the crowd at the steps is competing over a property that will go REO regardless of how aggressively they bid. What I find matters more than people expect is the bid-to-value ratio at origination, because a loan originated at 65 percent LTV five years ago in an appreciating market almost never produces an opening bid that threatens your margin the way an 80 percent LTV loan from 2022 does in a market that has since softened. That origination context is usually reconstructable from the recorded deed of trust, which is public. Have you been pulling the original loan amount against the origination-era AVM when you underwrite the opening bid, or are you working from current comps alone?

The postponement angle compounds everything you described: in many states a trustee sale can be postponed dozens of times, and each postponement resets the crowd but not the lender's bid math, which was set at a point in time that may now be months or years stale relative to current values. A bid floor calculated on a 2022 appraisal in a corridor that has since softened can look like a discount on paper and be at or above impaired value today. Before acting on any published opening bid, I would confirm the postponement history on that specific trustee file, then check what distressed sales in the same corridor have done in the six months since the most recent postponement, not since origination. The entity to confirm current bid calculation methodology with is the trustee directly, since some states allow lenders to adjust the credit bid between postponements and some do not. What does the postponement history look like on the sale you are tracking?

The comparison you want is not opening bid versus distressed comp, it is opening bid versus your all-in basis after carrying costs, because the auction is where you buy but the exit is where you get paid, and those two dates are rarely the same month. A trustee sale in a slow-moving market adds holding cost at a rate that most parking-lot math ignores: property taxes continue, insurance on a vacant property runs at a non-standard rate, and if there is a tenant in possession, the timeline to a clear title for resale can stretch six months past closing in states with strong unlawful detainer protections. A 20 percent discount to retail can become a 10 percent discount before you list, and that assumes nothing unexpected inside the walls.

The number I would want from you is the average days-to-resale in your specific county for trustee-acquired properties, not the statewide figure. That single input changes whether a given spread is a margin or a mirage, because carrying cost is linear and the discount is fixed at the moment the gavel drops. A county where REO title clears and resells in 90 days prices very differently from one where tenant protections and probate complications push that to 240, even on identical opening bids and comparable sales. Do you have a recent sale in the same county where you can back out what the buyer actually netted after hold period and exit costs, as opposed to what the gross spread looked like on auction day?

@reba_finch09 The piece I would add is that the lender's opening bid sometimes reflects a BPO run six to eighteen months before the sale date, which means in a declining market the floor can be stale high, and in a rising market it can give a false sense of margin. Before standing at any sale, I would confirm with the county trustee's office what the current posted bid actually is on the morning of the auction, because postponements and partial payoffs can reset that number the day before. The gap between the BPO vintage and today's impaired value is where most auction losses are born, and it never appears on the bid sheet. What date was the original notice of default filed on the property you are looking at, because that tells you roughly how old the lender's valuation math might be?
