Reading the comparison
Seller financing usually has a slightly higher rate and a balloon, but lower closing costs and faster close. Bank loans cost more upfront but offer 30-year fixed payment certainty without balloon risk.
Use seller financing when bank financing is hard (low income docs, unique property, urgent close), or to negotiate a lower price in exchange for the seller carrying a note. Just make sure you have a credible plan to refinance or pay off before the balloon hits.

How this calculator works
What this page estimates
This Seller Financing vs Bank Loan Calculator is built to give a quick, browser-based estimate for seller financing vs bank loan. Compare a seller-financed deal (typically amortized like a 30-year but with a 5–7 year balloon) to a standard bank mortgage. See payments, balloon amount, and total cost over the balloon period. 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 financing vs bank loan 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 financing vs bank loan 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.
How to Use
- Enter purchase price and down payment percentage.
- Enter the bank loan rate, term, and closing costs.
- Enter the seller financing rate, amortization period, balloon date, and (much lower) closing costs.
- Compare monthly payments and total cost over the balloon period.
Frequently Asked Questions
When is seller financing the right call?
When bank financing is hard (low W-2 income, unique property, no recent comps), when timing is urgent, or when the seller wants long-term passive income. Investors use seller financing for non-conforming deals all the time.
What rate do sellers typically charge?
Often slightly above market rate — they're taking on bank-equivalent risk without the bank's underwriting. 0.5–1.5% above conventional rates is common, sometimes higher for higher-risk deals.
What happens at the balloon?
You refinance into a conventional loan or sell the property. If you can't do either (bad credit, value drop, rate environment), the seller can foreclose. Plan multiple exit paths.
Are seller financing terms negotiable?
Very. Rate, term, balloon, prepayment penalties, even down payment are all on the table. The seller's motivation matters — a tax-conscious seller may prefer installment treatment; an investor seller may want passive income for years.
