Seller Carry Note Yield Calculator

Carrying the note back boosts seller yield but concentrates risk — compute the delta.

How the math works

Carry yield = sum of payments + balloon. Compare to alternative compounding at T-bill rate.

$525k note at 9% 25yr = $4,405/mo × 84 + $447k balloon = $817k. Alt 4.5% = $716k. Advantage $101k.

How this calculator works

What this page estimates

This Seller Carry Note Yield Calculator is built to give a quick, browser-based estimate for seller carry note yield. Carrying the note back boosts seller yield but concentrates risk — compute the delta. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the seller carry note yield result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this seller carry note yield estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions

Why would a seller carry?

(1) Gets higher yield than CD/T-bill on cash proceeds. (2) Installment sale method spreads gain tax over years (IRC 453), reducing tax bracket impact. (3) Helps buyer qualify who can't get conventional financing. (4) Enables premium sale price (buyer pays 5-10% more for seller financing). (5) Retirement income stream for seller. Most common in rural markets, niche properties, and small commercial.

Risks to seller?

(1) Borrower default + property value decline = loss. (2) Concentrated risk vs diversified cash portfolio. (3) Slower access to cash (locked in note). (4) Tax on note sale (if you later sell to a note buyer). (5) Junior position if buyer takes senior mortgage + seller carries junior. Foreclosure + resale cost 15-25% of sale price on average. Seller financing only makes sense with strong buyer credit or substantial down payment (30%+).

Typical carry terms?

Rate: market + 100-300 bps (8-12% typical in 2024). Term: 15-30 year amortization. Balloon: 3-7 years (forces buyer to refinance). Down payment: 20-30% standard, 10-15% for strong buyers. Interest-only first 1-2 years: increasingly common. Recourse vs non-recourse: recourse preferred by seller. Full due-diligence on buyer: essential.

Installment sale tax?

IRC 453 installment method: report gain proportionally as principal payments received. Example: sale $1M, basis $600k, gain $400k (40%). $300k down + $700k note at 8%. Down payment gain: $120k (40% of $300k). Note payment gain ratio: 40% of each principal payment. Spreads tax bracket. Catches: depreciation recapture (still taxed in year of sale regardless of installment), no installment method for dealer property.
