The Pre-Bid Waterfall Process for Note Due Diligence

Why You Need a Pre-Bid Screening Process

When a data tape lands in your inbox with fifty or a hundred non-performing loans, you cannot afford to run comprehensive due diligence on every single asset. Ordering BPOs, credit reports, and title searches on loans that turn out to be unsecured or have no equity wastes both time and money. The pre-bid waterfall process solves this problem by establishing a sequence of free, publicly available research steps that progressively filter out non-viable loans before you commit any capital to vendor data.

This is the analysis you perform before submitting an indicative bid or a complimentary portfolio analysis to a seller. Every check in the waterfall uses free online tools and public records, which means you can run through it at zero cost. Loans that survive each stage of the waterfall advance to the next. Loans that fail get flagged, repriced, or eliminated entirely. By the time you reach the end, the remaining loans are the ones worth spending money on — and the ones you can confidently price in your initial offer.

The Waterfall: Stage by Stage

The waterfall is an ordered sequence. The order matters because early stages eliminate loans that would waste your time in later stages. If a loan fails at stage one, there is no reason to research its property value or occupancy status.

Each stage is designed so that a single person — or a trained virtual assistant — can execute it using only a web browser and public websites. For large pools, delegate the research and have results delivered in a spreadsheet so you can focus on pricing and deal negotiation rather than data entry.

Stage 1: Secured vs. Unsecured

This is the most important filter in the entire waterfall and the single biggest driver of price. A secured note means the lien is still attached to the property, which gives you the ability to pursue foreclosure as a remedy. An unsecured note means the lien has been released or the borrower no longer owns the property — and your only option is to pursue the debt as an unsecured obligation based on the promissory note alone.

The hard-and-fast rule: if the borrower still owns the property and no lien release has been recorded, the loan is secured. You verify this by checking the county records to confirm that the name on the loan documents matches the current property owner.

False Positives and False Negatives

This check is not always straightforward. Two scenarios can produce misleading results:

False positive — borrower owns the property, but the lien has been released. The borrower's name still matches the property owner in county records, which looks like a secured loan. But if a satisfaction or lien release has been recorded, the lien is no longer attached to the property. The debt exists, but it is unsecured. Always check the recorded documents on the property for any satisfaction or release filings.

False negative — borrower no longer owns the property, but the lien is still secured. The borrower transferred the property to another party, so the names do not match. At first glance this looks unsecured. However, if the transfer was executed via a quit claim deed or another conveyance that was subject to existing liens, your lien survived the transfer. The new owner took the property with your mortgage still attached. This requires reading the actual deed of transfer in the public records to determine whether existing liens were preserved.

These edge cases are why a simple name-match check is necessary but not sufficient. When the borrower name does not match the property owner, investigate the transfer history before writing off the loan as unsecured.

Stage 2: Lien Position

Lien position — whether the loan is a first lien or a junior lien — is typically provided by the seller on the data tape. At the pre-bid stage, you generally do not need to independently verify position through a title search. That verification happens later during comprehensive due diligence after your letter of intent (LOI) is accepted.

What you do need at this stage is to confirm that lien position is populated for every loan on the tape and that your pricing model aligns with the position. First liens and second liens require fundamentally different pricing frameworks:

If lien position is missing from the tape, request it from the seller before proceeding. Never assume position.

Stage 3: Collateral Value

Once you have confirmed that a loan is secured and you know the lien position, the next question is what the collateral is worth. Property value is the foundation of your pricing model — for first liens it directly drives your offer price, and for junior liens it determines how much equity stands between your position and a loss.

At the pre-bid stage, use free automated valuation models (AVMs) and a self-performed desktop appraisal to establish an initial estimate of fair market value (FMV). Pull values from multiple free sources — Zillow, Redfin, Realtor.com — and look at recently sold comparable properties in the same neighborhood. This costs nothing and takes 15 to 30 minutes per property for a thorough desktop analysis.

This is also where you can start providing value to the seller. Many sellers — especially non-professional sellers who inherited a small portfolio or are liquidating a few assets — may not have current property values in their spreadsheet. Some may not even have a spreadsheet at all. Constructing that analysis and presenting it back to the seller as a complimentary portfolio analysis is a powerful way to earn the trade. You are demonstrating competence and providing useful information, which builds trust and positions you favorably against competing buyers.

Stage 4: Other Liens and Equity

Property value alone does not tell you how much equity secures your position. You need to subtract everything that sits ahead of you in the priority stack.

For first liens, equity is relatively straightforward:

Equity = Property Value - Outstanding Property Taxes

Property taxes are a super-priority lien that sits ahead of all mortgages. Check the county tax assessor website to find the current tax balance. A property worth $100,000 with $15,000 in delinquent taxes has $85,000 of equity securing your first-lien position.

For junior liens, the calculation is more involved:

Equity = Property Value - Senior Lien Balance - Outstanding Property Taxes

You need to know not just the property value but also the unpaid principal balance of the first-position mortgage. If the seller has provided the senior lien balance on the tape, use it. If not, this data point may need to wait until you order a credit report during comprehensive due diligence.

Beyond the senior lien balance, the status of the senior lien is critical for junior lien pricing. A non-performing second lien behind a current first-position mortgage with equity — especially if the property is owner-occupied — is the highest-value second lien you can buy, often pricing at 60% or more of UPB. A non-performing second behind a delinquent first is a fundamentally different risk profile, because the senior lien holder could foreclose and wipe out your junior position entirely.

Professional sellers often provide senior lien status on the tape or include credit reports with the data package. Non-professional sellers typically do not have this information. If senior lien status is unavailable at the pre-bid stage, note the gap, factor uncertainty into your pricing, and plan to order credit reports during your comprehensive due diligence period.

Stage 5: Bankruptcy Status

Check PACER (Public Access to Court Electronic Records) to determine whether the borrower has an active bankruptcy filing. An active bankruptcy case does not necessarily disqualify a loan, but it changes the timeline, the available resolution strategies, and the legal complexity. It must be factored into your pricing.

PACER is a free federal database (with minimal per-page fees for document access) that allows you to search by borrower name and identify any open or recently closed bankruptcy cases. At the pre-bid stage, you are looking for the presence or absence of an active case and, if active, which chapter it falls under — Chapter 7 (liquidation) and Chapter 13 (repayment plan) have different implications for note investors.

Stage 6: Occupancy Status

The final stage of the pre-bid waterfall is determining whether the property is owner-occupied, tenant-occupied, or vacant. Occupancy status directly influences your resolution strategy, your expected timeline, and your pricing.

You can assess occupancy at no cost using two complementary methods:

Google Street View and satellite imagery. Navigate to the property address and examine the most recent available images. Look for signs of vacancy: overgrown yard, boarded or broken windows, accumulated debris, a caving roof, or disconnected utilities. Check the image capture date — Street View images can be significantly out of date, sometimes by several years. Satellite imagery is typically more recent than street-level photos, but street-level views provide better detail on property condition.

Property tax mailing address. When you check the county records for property taxes (which you already did in Stage 4), note the address where the homeowner receives their tax statements. If the tax mailing address matches the subject property address, the owner is most likely living in the home — it is owner-occupied. If the mailing address is different, the homeowner is receiving tax bills at another location, which strongly suggests the property is not owner-occupied.

Neither method is definitive on its own, but together they provide a reasonable confidence level for pre-bid pricing purposes. Definitive occupancy verification — through a door knock, a field inspection, or a BPO with an interior or exterior inspection — comes later during comprehensive due diligence.

When to Pass vs. When to Proceed

Not every loan that survives the waterfall deserves a bid, and not every loan that fails a single stage should be discarded. The waterfall is a screening tool, not an absolute filter. Here is how to think about the decision at each stage:

The purpose of the waterfall is not to find perfect loans. It is to allocate your time and money efficiently by identifying which loans justify the expense of full due diligence — and which ones can be priced, flagged, or eliminated based on free research alone.

Scaling the Waterfall with Your Team

For small pools, you can run the waterfall yourself in an afternoon. For larger portfolios, delegate it. Train a virtual assistant or team member to execute each stage and record results in a standardized spreadsheet with columns for: borrower name, property owner match, satisfaction/release status, secured conclusion, lien position, estimated property value, outstanding taxes, senior lien balance, calculated equity, bankruptcy status, occupancy assessment, and tax mailing address.

With this data populated, you can review an entire pool in minutes and present a professional analysis to the seller that demonstrates competence and seriousness as a buyer.

From Waterfall to Offer

The pre-bid waterfall produces enough information to submit an indicative bid — a preliminary offer that is subject to complete due diligence. This offer tells the seller what you are willing to pay based on the information available, with the understanding that your final price may adjust once you order vendor reports and conduct a thorough review.

If the seller accepts your indicative offer or LOI, you enter an exclusive due diligence period where you spend money on BPOs, credit reports, title searches, and other vendor data to verify every assumption you made during the waterfall. Based on those findings, you either confirm your price, negotiate a reduction on specific loans, or remove loans from the pool entirely.

The waterfall does not replace comprehensive due diligence. It ensures that when you do spend money on due diligence, you are spending it on loans that have already passed the most basic viability tests — and that is the difference between a disciplined investment process and an expensive guessing game.
