The Beginner's Guide to Due Diligence on Performing Notes

Performing notes require a different due diligence checklist than NPLs — covering seasoning, loan mod quality, credit reports, and real servicing costs.

Most DD Guides Assume You Are Buying Non-Performers

Open any due diligence resource in the note investing space and you will find pages of guidance on checking occupancy, estimating rehab costs, and pricing around foreclosure timelines. All of that matters when you are buying a non-performing loan. But performing notes — loans where the borrower is already making payments under a current modification or original terms — carry a completely different set of risks. The property condition still matters, but it is no longer the centerpiece of your analysis. What matters most is whether those monthly payments will continue, how well the loan modification protects you, and whether the numbers on the seller's spreadsheet match reality.

This guide covers the nine core due diligence items for reperforming first and second mortgages. Some overlap with NPL due diligence exists, but the emphasis shifts significantly. If you are moving from non-performing to performing notes, treat this as a reset — not an abbreviated version of what you already know.

Who Is Selling You This Note?

Before you examine a single document or pull a single report, evaluate the note seller. Their reputation, their track record, and the quality of information they provide set the tone for the entire transaction.

A credible seller with a history of clean deals will typically supply a title search, a credit report, payment history, and collateral images upfront. They want top dollar for their asset, and the way they get it is by giving you the data you need to bid with confidence. If a seller provides a sparse spreadsheet with no supporting documentation, that tells you something about how the rest of the transaction will go.

Build a database of sellers over time. Google their name. Ask around in your network. Check whether their representations on past trades matched reality after closing. The sellers you trust will be the ones where you can bid more aggressively — not because you skip due diligence, but because you have a track record of receiving accurate information from them.

One practical step many new investors overlook: clean up the seller's data tape before you start your analysis. Delete columns that do not contribute to your pricing decision. The raw spreadsheet might have 40 or 50 columns, but only 10 to 15 drive your bid.

What Should the Title Report Tell You?

The title report is a non-negotiable item on both performing and non-performing deals. It provides a detailed overview of the property's legal status — who owns it, what liens and encumbrances are recorded against it, and whether the assignment chain connecting you to the original mortgage is intact.

With performing notes, investors sometimes assume the title is clean because the borrower is making payments. That assumption can cost you. One real example: a reperforming second mortgage purchased from a reputable seller, no title report ordered. Six months into receiving payments, information surfaced that the property was heading to tax sale. The borrower was current on both mortgages, but property taxes had gone delinquent. The homeowner eventually reinstated the taxes — but a title report at the time of purchase would have flagged the delinquency before funds were wired.

Beyond taxes, the title report confirms:

  • The current owner on record matches the borrower on the loan
  • No lien release or satisfaction has been recorded that would make your loan unsecured
  • The assignment chain from the original lender through every subsequent holder to the seller is documented and recorded
  • No unexpected encumbrances — IRS liens, judgment liens, HOA liens — sit ahead of or alongside your position

If the seller does not supply a title report, budget $75 to $200 for an Ownership and Encumbrance (O&E) report and order it on day one of your due diligence period.

How Property Taxes and Insurance Differ on Performing Notes

When you buy an NPL, delinquent taxes and lapsed insurance are almost expected. You price around them. With a performing note, the expectation flips. The borrower is making payments, so there is a reasonable assumption that taxes are current and homeowner's insurance is in force. But "reasonable assumption" is not due diligence.

Property taxes. Check the county tax assessor website for the subject property. Confirm the current-year and prior-year balances. If the borrower's modification includes an escrow component that covers taxes, verify with the loan servicing company that taxes are actually being paid from the escrow account. Escrow accounts can run short, and not every modification includes an escrow requirement. Taxes sitting outside escrow on a reperforming note are a line item that can quietly go delinquent while you are collecting monthly payments and assuming everything is fine.

Homeowner's insurance. Whoever resolved the NPL and created the modification should have required the borrower to obtain legitimate homeowner's insurance. Confirm that a valid policy exists, that you will be listed as loss payee, and note the policy's expiration date. If coverage lapses after closing without notice, you are exposed on collateral that could be damaged or destroyed with no recourse.

Both items are ongoing asset management responsibilities, but the initial due diligence is where you establish the baseline.

How Much Is the Property Actually Worth?

Property value matters on performing notes, but the level of precision you need depends on whether you are buying a first or a second.

Reperforming first mortgages. Because you hold the senior position, a default could end with you taking back the property. Order a BPO (broker's price opinion) from a local agent — the $75 to $150 cost is worth it for boots-on-the-ground data no AVM can replicate.

Reperforming second mortgages. Your primary concern is whether enough equity exists behind the first mortgage to cover your position. For many experienced second-lien investors, triangulating free AVM data from Zillow, Redfin, Trulia, and Realtor.com produces a sufficient estimate. You are unlikely to foreclose and take back the property on a second lien, so the precision threshold is lower — but you still need an approximate value for your equity calculation.

Regardless of lien position, run a quick search on the borrower's name and property address. Look for red flags: active litigation, code violations, or anything suggesting the property's condition does not match the seller's representations.

Why the Credit Report Is the Most Important Document for Second Lien Investors

For second mortgage note investors, the credit report is arguably the single most valuable due diligence document — even more important than the title report. It provides visibility into the borrower's full financial picture and, critically, the status of the first mortgage that sits ahead of your position.

Here is what to look for on the credit report:

First mortgage status. The credit report should show the first mortgage trade line with the current balance, payment status, and servicer name. Confirm that the first is current. If the seller told you the first mortgage balance is $80,000 and the credit report shows $95,000, you have a discrepancy that affects your equity calculation and your bid.

Borrower identity verification. Match the borrower's name, Social Security number, and date of birth against the loan documents. The credit report often lists multiple addresses with the length of time at each — useful for determining whether the property is owner-occupied or a rental.

Debt load. Some investors use the credit report as a rough filter: if it runs eight pages or more, the borrower is carrying significant debt, which increases re-default risk regardless of current performance.

First mortgage deep dive. Once you identify the first mortgage servicer from the credit report, look up their 800 number and call the automated phone system. You can typically access account information using the borrower's Social Security number and the property zip code. Confirm the balance, confirm the loan is current, and note the monthly payment. Stick to the automated system — do not speak with a live representative.

If the first mortgage information does not appear on the credit report at all, it is likely because the borrower was discharged from a Chapter 7 bankruptcy — the trade line stopped reporting, but the lien still exists. You will need another method to verify the first mortgage status.

A note seller should supply a credit report during due diligence on any reperforming note. If they do not, order one through CoreLogic or TransUnion before committing to a purchase price.

Does Bankruptcy History Change Your Bid?

Yes — and you need to check it on every deal, performing or not. PACER (Public Access to Court Electronic Records) is a federal database that logs every bankruptcy case ever filed. Set up a free account and search the borrower's name.

Two scenarios to understand:

Chapter 7 discharge. The borrower's personal liability for the mortgage debt has been eliminated — they cannot be sued for a deficiency. However, the lien still exists on the property. If the borrower signed a loan modification after the discharge, that modification contains language acknowledging the lien remains and the borrower is agreeing to make payments to keep the property. This is a standard scenario in the reperforming note market and not a deal-killer, but you need to understand the enforceability dynamics.

Chapter 13 completion or dismissal. Chapter 13 is a 3-to-5-year repayment plan. If the borrower completed the plan and received a discharge, they cleaned up their arrearages through the bankruptcy process. If dismissed, the protections ended and any remaining arrears reverted to their original status. Either outcome tells you what the borrower has been through financially.

Some reperforming notes are actively inside a Chapter 13 plan — the borrower makes pre-petition arrears payments through the plan while making current loan modification payments outside it. These deals are more complex but can be purchased at a discount that compensates for the added management overhead.

What the Collateral File and Payment History Reveal

The collateral file contains the legal documents that make your investment enforceable. The payment history tells you whether the borrower's track record supports the seller's asking price.

Collateral file review. Request images of the following before you agree to a final purchase price:

  • The recorded mortgage or deed of trust
  • The original promissory note with allonges and the complete endorsement chain
  • The recorded assignment chain connecting the original lender to the seller
  • The draft allonge and assignment that will transfer the note to you
  • The current loan modification agreement

Not every trade includes the complete origination file, but the modification, the note, the mortgage, and the assignment chain are essential.

Loan modification quality. Not all modifications are created equal. Read the modification agreement carefully and look for:

  • The modified principal balance — is it the full amount owed, or was a portion deferred?
  • The interest rate and monthly payment amount
  • The term (how many payments remain)
  • Whether the borrower made a down payment to enter the modification, and how much
  • Whether the modification includes an escrow requirement for taxes and insurance

A borrower who put $10,000 down to enter a modification has materially more skin in the game than one who put $1,000 down. Both can work, but the down payment amount affects how you price the note and the yield you require.

Payment seasoning. This is one of the most critical data points for any performing note purchase. How many payments has the borrower made, and have they all been on time? A note with 48 consecutive on-time payments is a fundamentally different asset than one with 6 payments and a couple of late marks. More seasoning means lower re-default risk, a lower required yield, and a higher price you are willing to pay. Less seasoning means more uncertainty and a higher yield demand.

Request the full loan accounting and payment history from the seller's servicer — every payment received, every payment posted, any late fees assessed, and the current loan balance breakdown.

How to Calculate Your Purchase Price Using Yield

Performing notes are priced on yield — the annual return based on the price you pay, the monthly payment you receive, and the remaining term. This differs from NPL pricing, which is typically driven by property value or a percentage of UPB.

The standard tool is the 10BII financial calculator app (around $6). Five inputs drive every performing note price:

ButtonInputDescription
NNumber of paymentsTotal remaining monthly payments on the modification
I/YRYieldYour target annual yield (not the note's interest rate)
PVPresent valueThe purchase price (this is what you are solving for)
PMTPaymentThe monthly payment amount, entered as a negative number
FVFuture valueAny deferred balance or balloon due at loan maturity (negative if applicable)

A practical example: a reperforming note with 200 remaining payments, a $457 monthly payment, no deferred balance, and a 12% target yield. Enter N=200, I/YR=12, PMT=-437 (the $457 payment minus $20/month servicing), FV=0. Hit PV, and the calculator returns your purchase price at that yield.

Two adjustments experienced investors build into their bids:

Payment buffer. Instead of calculating on all 200 remaining payments, subtract 12 off the top and calculate on 188. This builds a cushion for re-default risk or early payoff scenarios. Scale the buffer to the remaining term — 12 payments off a 350-payment note is modest; 12 off a 60-payment note is aggressive.

Yield adjustment for risk. If the loan modification package is strong (large down payment, solid seasoning, complete documentation), you might accept a 10-12% yield. If the package is weak (minimal down payment, short seasoning, missing documents), bump your target to 13-14%. The yield is your risk premium, and it should reflect what you found during due diligence.

What Are the Real Costs After You Buy?

Your purchase price is not your total cost. Post-acquisition expenses eat into your yield and need to be factored into your bid — not discovered after closing.

Assignment recording fees. The assignment transferring the mortgage to you must be recorded with the county. Fees vary widely: some counties charge $20, while others (particularly in New York and Pennsylvania) charge $200 or more. Check the fee schedule before you finalize your bid.

Loan servicing setup and monthly fees. Most investors place performing notes with a licensed loan servicing company rather than self-servicing. Typical costs are $50 to $100 for loan setup and $15 to $25 per month for ongoing servicing. The monthly fee is deducted from the borrower's payment before you receive it — a $457 payment with a $20 servicing fee means you net $437. That $20 difference compounds over the life of the loan, which is why you should calculate your purchase price using the net payment, not the gross.

Self-directed IRA costs. If you hold notes through a self-directed IRA custodian, factor in the account setup fee and the annual accounting fees. These vary by custodian and by the number of assets in the account.

Foreclosure cost reserve. Even on a performing note, understand the cost of legal action in the property's state. Judicial states can run $5,000 to $10,000+ in legal fees; non-judicial states are typically $1,500 to $3,000. You are not expecting to foreclose, but knowing the cost informs how much cushion you need in your pricing.

Nine Items, One Process

The performing note due diligence checklist comes down to nine categories:

  1. Note seller reputation and track record — Know who you are doing business with before you evaluate what they are selling.
  2. Lien position and title status — Confirm your loan is secured, the assignment chain is intact, and no surprises are recorded against the property.
  3. Property tax status and homeowner's insurance — Verify both are current, even when the borrower is paying.
  4. Property condition and occupancy — Scaled to lien position: BPO for firsts, AVM triangulation for most seconds.
  5. Property value and equity position — Calculate how much equity stands behind your loan, especially on junior liens.
  6. Borrower credit report — The primary tool for verifying first mortgage status on seconds, confirming borrower identity, and gauging debt load.
  7. Bankruptcy history — Check PACER on every deal. Chapter 7 discharges and Chapter 13 plans create specific dynamics you need to price around.
  8. Collateral file, loan modification, and payment history — Review the documents that make your investment enforceable, assess modification quality, and evaluate payment seasoning.
  9. Total acquisition costs and fees — Recording, servicing, custodial, and legal reserve costs all affect your net yield and purchase price.

The emphasis shifts between firsts and seconds — credit reports carry more weight on seconds, property value carries more weight on firsts — but nothing on the list is optional. A performing note with 48 months of perfect payment history can still be sitting on a tax-delinquent property with a gap in the assignment chain and a borrower in active Chapter 13. The only way to know is to check.

Where Performing Note DD Diverges From NPL DD

If you are coming from the non-performing side, the biggest mental shift is this: with an NPL, due diligence is about sizing the downside. How much will foreclosure cost? What is the property worth in its current condition? Can you contact the borrower, and will they engage?

With a performing note, due diligence is about validating the income stream. The borrower is already paying. Your job is to determine how reliable that income is, how well the documents protect your position, and whether the price you pay produces an acceptable yield after all costs. The risk is not that you end up with a vacant property. The risk is that you overpay for a payment stream that stops — and you lack the documentation, equity coverage, or legal standing to recover.

Different risk. Different checklist. Same discipline.
