Common Lending Mistakes That Quietly Cost Investors Money

Several common mistakes P2P lending investors make look reasonable when viewed one claim at a time. A higher rate adds interest on paper. A string of on-time payments makes it easier to approve another claim. The cost of these behavioral mistakes in investing tends to show up elsewhere in the portfolio, for example when a repayment arrives too late to fund the next claim.

Picking the loan with the highest advertised rate

Is it a mistake to always pick the highest interest rate?

Yes, if the comparison ends with the advertised rate. One reason why investors chase the highest interest rate is that they can see the extra interest before committing any money. The missed income from a late payment depends on when the money actually comes back and what it could have earned in the meantime.

Take two one-year claims of €1,000 with a two-percentage-point rate difference. The higher rate adds €20 in scheduled interest. If that claim returns principal 90 days late with no extra interest, the other claim’s principal could earn about €25 during those same 90 days at an assumed 10% annual rate. That would wipe out the €20 advantage. All figures in the examples are hypothetical.

Maclear uses Annualized Return on Investment (AROI) as its primary return metric. A risk-adjusted comparison asks how that return might change if payments arrive late or the lender recovers less than expected. The borrower’s credit grade can put the quoted rate in context, while the cash available to service the debt helps assess whether the borrower can pay the extra interest on schedule.

Assuming no recent defaults means lower risk

What is recency bias in lending decisions?

Recency bias in investment decisions is the tendency to give recent experience more weight than the rest of the evidence. In lending, a quiet stretch can make an unchanged set of borrowers feel less risky. A short record is especially easy to overread when few loans have reached maturity or borrowers have yet to face a difficult trading period.

A portfolio with €5,000 exposed to a borrower could have €10,000 exposed after an investor doubles the position on the strength of a few quiet months. A later 10% principal shortfall would then cost €1,000 instead of €500. The repayment record helped explain the investor’s confidence, while the change in position size determined the extra loss.

A full credit cycle gives an investor a chance to see how borrowers cope when trading weakens or refinancing gets harder. If the available record covers only the good months, it offers little basis for estimating losses in a downturn.

Staying concentrated in what feels familiar

An investor who knows a particular industry can often read a borrower’s accounts faster and ask better questions. That makes the next claim in the same industry easier to approve. If several borrowers depend on the same local customers, a drop in orders can hit those claims together.

If 60% of a portfolio sits in one sector and those claims suffer a 10% principal shortfall, the sector takes six percentage points off the portfolio’s value. At a 30% weight, the same shortfall takes off three points. The difference comes from allocation, even if every borrower looked reasonable in isolation.

Spreading claims across countries and sectors starts with asking which borrowers could come under pressure at the same time. Several businesses can depend on the same customers or local economy. The size of each claim matters too, because it determines how much a single default can cost the portfolio.

Selling a claim at a discount before the outcome is known

Should a loan claim be sold at a discount as soon as a payment is late?

A missed payment is a reason to check the borrower’s latest update before deciding what the claim is worth. A payment becomes late when it misses its due date. Default is a separate status under the loan’s terms. The cause of the delay and the borrower’s ability to catch up both matter when weighing a sale at a discount.

Consider an investment claim with €1,000 in outstanding principal, six months remaining and one late payment. A completed sale at a 20% discount brings in €800 before fees and locks in a €200 loss against the outstanding principal. If the borrower subsequently catches up and repays the loan in full, that €200 is principal the seller would have recovered by holding the claim. The example isolates the discount from fees and future interest.

On Maclear’s Secondary Market, sellers can list claims at par or at discounts up to 50%. A sale depends on another investor taking the listing. An actual need for cash can justify accepting a discount, while a missed due date on its own says little about what that discount ought to be.

Letting cash sit idle between loans

Why does idle cash hurt portfolio returns?

Cash drag in P2P lending arises when repaid capital spends part of the year outside an interest-earning claim. A claim can perform exactly as scheduled while the portfolio earns less over the year because its capital is deployed for fewer days.

Suppose a €1,000 claim is repaid and the money sits idle for 20 days out of 365. At an assumed 10% annual AROI, using a simple daily approximation, the foregone return is €1,000 × 10% × (20 ÷ 365) ≈ €5.48, or about €5.50 for the cycle. Three such gaps on the same balance would cost about €16.44 under the same assumptions, without a single default.

Keeping cash accessible for a known expense serves a purpose. Avoidable downtime often starts when the search for the next claim begins only after repayment. Tracking scheduled repayments gives investors time to review new claims in advance and apply their usual lending criteria.

Adding more money to a borrower already in trouble

A discounted claim on a borrower that already has trouble paying can look like a chance to lower the average entry price. The lower price changes the cost of the new claim. Both claims still depend on the same borrower finding enough cash to pay.

Suppose the investor holds €1,000 at face value and spends another €500 on €625 of claims against the same borrower. If the borrower ultimately repays 40% of face value on both positions, the extra purchase returns €250. The discount lowered the entry price, but the investor still loses another €250 on top of the €600 loss on the original position.

The case for adding funds changes if a borrower actually secures new financing or its accounts show that operating cash flow has improved. Until then, a lower price changes what the investor pays for the claim while the borrower faces the same repayment problem.

None of these six mistakes requires a bad loan to cost money - each one turns an otherwise sound claim into a worse outcome through the timing or sizing of the investor's own decision.

FAQ

Is it a mistake to always pick the loan with the highest interest rate?

Yes, if the rate is considered in isolation. A higher rate can compensate for a greater chance of delayed or incomplete repayment. The borrower’s credit grade is one input in assessing how much of that rate advantage could survive a delay or a principal shortfall. The comparison is between risk-adjusted outcomes.

What is recency bias and how does it affect lending decisions?

Recency bias is the tendency to let recent experience dominate a risk assessment. Several months without a default can make a portfolio feel stronger even when borrower finances have barely changed. That impression can lead an investor to commit more capital just before weaker conditions test the same borrowers.

Should a loan claim be sold at a discount as soon as a payment is late?

A late payment alone is insufficient grounds for an automatic sale. A borrower can still catch up, and a completed sale makes the discount permanent for the seller. Evidence of deteriorating repayment capacity or a genuine need for immediate cash can change how that trade-off looks.

Why does idle cash between loans hurt portfolio returns?

Undeployed money earns no AROI from lending claims. The gap matters at portfolio level because the annual result includes the days when the cash was idle. Several short gaps can cut into annual earnings even when every funded claim pays the full amount due.

Is it a mistake to add more money to a borrower who is already late on payments?

Yes, when a cheaper entry price or the desire to salvage the original position is the main reason for adding funds. The additional claim increases exposure to the same repayment problem. New, verifiable information about the borrower’s ability to pay can provide a separate basis for reassessing the position.
