Note Investing Red Flags: What to Watch Before You Buy

Note investing offers the potential for consistent cash flow and long-term returns—but only when deals are properly vetted.

Performing or non-performing notes, overlooking key warning signs, can quickly turn a promising investment into a costly problem. The good news is that most bad deals leave clues.

Detecting Note Investing Red Flags

As a Note Buyer (or Broker), you’re going to want to get a good detective hat, because note deals take a little sleuthing and investigation.

Borrower Red Flags

The borrower is where your payments come from, so it’s worth taking the time to look at them. While you don’t need to haul them down to the station and put them through an interrogation (that’s against the Fair Debt Collection Practices Act), you do need to keep an eye out for any warning signs.

Recent Missed Payments with Major Life Changes

A borrower who has recently missed payments due to job loss, medical issues, or divorce may be facing ongoing financial instability. While these situations can sometimes be temporary, they often signal a higher likelihood of continued delinquency if the circumstances aren’t managed.

Unpaid Property Taxes

Delinquent property taxes are a serious red flag. Tax liens typically take priority over your mortgage, meaning you could lose your position—or even the property—if taxes remain unpaid. Was this a one-off situation or a pattern? Is there a willingness to get back on track?

Sudden Drop in Credit Score

If the borrower’s current credit profile doesn’t align with the Seller’s claims, dig deeper. A recent drop in credit score could indicate mounting debt, missed obligations, or financial distress that hasn’t yet surfaced in payment history. Recent or habitual bankruptcy filings can also be a sign to dig deeper.

Defensive or Uncooperative Borrower

None of the above are deal-breakers and are worth discussing with the Seller and borrower. But if a borrower becomes defensive or evasive when contacted, it may signal deeper issues.

Borrowers who are unwilling to communicate are generally harder to work with if problems arise later.

A strong borrower profile doesn’t eliminate risk — but a weak one significantly increases it.

Property Red Flags

Since the property secures the note, its condition directly impacts your exit strategies.

Neglected Maintenance

A poorly maintained property can indicate financial stress or neglect. Overgrown lawns, peeling paint, or visible damage may also suggest deferred maintenance inside.

More than that, has the deferred maintenance become a safety hazard? Are things like the roof or windows no longer in working condition?

Declining Neighborhood

If the surrounding area shows signs of decline—such as increased vacancies, crime, or falling property values—it can limit your ability to resell or rent the property if needed.

Environmental Concerns

We’ve seen several devastating natural disasters in the past few years, including fires, hurricanes, and floods.

Is the property in a recently impacted area? Or does it have the necessary insurance, such as flood or fire, for its area?

Remember: your worst-case scenario is often taking the property back. Make sure it’s an asset you’d actually want to own.

Seller Red Flags

The Seller offers transparency – or so you hope. If something feels off, it’s worth paying attention.

Cagey or Evasive Behavior

If a seller avoids answering basic questions or provides vague responses when you’re trying to quote a deal, that’s a major warning sign. Transparency is essential in note investing. Are they just a cautious seller, or are they trying to conceal less-than-ideal facts?

Creating Multiple Notes Without Proper Guidance

Sellers who have created multiple notes without using a Mortgage Loan Originator (MLO) or legal advisor may have improperly structured documents. Not only that, there could be compliance issues.

A note is only as good as it starts – so make sure it is in good standing and created above board.

Reluctance to Follow Due Diligence Protocols

If a seller pushes back on standard due diligence, such as providing documents, allowing servicing verification and property valuation, or permitting title review, it’s a sign they may be hiding something.

A trustworthy seller should be willing to provide documentation and allow you the time needed to evaluate the deal properly.

Invest, but Verify

Every note investment comes with some level of risk — but avoidable risks are the ones that hurt the most. By identifying note investing red flags early, you can filter out problematic deals and focus on assets that align with your investment goals.

Strong due diligence isn’t just about checking boxes—it’s about asking the right questions, verifying the details, and staying disciplined when something doesn’t add up. Get the confidence to make the right choices for your goals with our Due Diligence Master Class.
