Comparing a cash offer with payments over time

A dollar today is not the same as a dollar later

Money you receive now can be used now: to pay off debt, buy another home, invest, or simply provide a cushion. Money promised later cannot. Economists call this the time value of money. Inflation also erodes what future dollars can buy, and waiting has an opportunity cost because you cannot use the money in the meantime.

Interest on a seller-financed note is meant to compensate you for waiting. Whether the rate actually does that depends on the rate itself, the length of the note, and what else you could do with the money.

A hypothetical side-by-side

Imagine, purely for illustration, two proposals on the same house. Proposal A pays 200,000 dollars at closing. Proposal B pays 240,000 dollars in total: 20,000 dollars down and the rest over time with interest. On paper, B looks 40,000 dollars better.

Now adjust B. The 20,000 down arrives at closing, but the remaining balance arrives over years. If you would otherwise have invested the money, part of that 40,000 difference is simply the cost of waiting. If the note includes a balloon payment that depends on the buyer refinancing, a large share of the money is uncertain. If you pay a servicer, an attorney, and possibly collection costs, the gap narrows further. These figures are hypothetical, and your own comparison should use your real numbers with a financial professional.

Risk: will the payments actually arrive?

A cash closing, once funded, is finished. A note depends on the buyer paying every month for years. Buyers lose jobs, tenants leave, repairs pile up, and markets shift. If the buyer defaults, you may need to go through notices and foreclosure or another state process, with costs and delays.

Ask what protects you: the size of the down payment, your lien position, the buyer's track record, and whether taxes and insurance stay current. The higher the risk, the more the promised total should exceed the cash figure to be worth it.

Certainty and timing

Certainty has value of its own. A seller relocating, settling an estate, or ending a landlord role may care more about a clean, final closing than about a higher total that stretches into the future. With a cash sale, you also generally avoid ongoing responsibilities such as tracking payments, checking insurance, and watching property taxes.

On the other hand, some sellers welcome steady monthly income and have no immediate need for a lump sum. For them, a well-secured note at a reasonable rate can fit their plans.

Comparing net proceeds, not headline totals

For each proposal, estimate what actually reaches you. Start from the price and subtract your mortgage payoff, liens, closing costs you pay, commissions if any, and expected professional fees. For payments over time, also consider servicing costs, the effect of default risk, and taxes. Payments over time may be reported under the installment method, while interest is generally taxed as ordinary income. A tax professional should run both scenarios.

• Cash at closing, after payoffs and costs
• Total future payments and the schedule they follow
• Interest rate and whether any balloon depends on refinancing
• Ongoing costs: servicing, legal, insurance monitoring
• Tax treatment of principal, gain, and interest

Mixed approaches

Some proposals combine a cash payment at closing with a smaller note, or pair cash with other terms. These can balance certainty against a higher total, but every part still needs the same review: clear documents, real security, and a realistic look at risk.

When you review a mixed proposal, separate the two pieces. Ask what the cash portion alone nets you after payoffs and costs, then judge the note on its own terms: its rate, length, security, and the buyer's ability to pay. A generous cash portion does not make a weak note safer, and a strong note does not make up for cash that barely covers your payoff.

How Prominent approaches it

Prominent Cash Offer buys houses nationwide for cash in any condition. On cash purchases there are no fees or commissions, Prominent pays the closing costs, you choose the closing date, and the written offer carries no obligation. Cash is the primary path. Flexible arrangements, including combinations of cash and terms, are evaluated case by case, and not every property, seller, or state qualifies. Whatever you compare, put both options in writing and review them with your own advisers.
