You have probably seen the post on social media. "Back in 1981, mortgage rates were 18%. Today's buyers should be grateful."

The number is real. But something about that argument has never sat right with me, because houses in 1981 did not cost what they cost today. After 27 years in mortgage lending, I can tell you the rate is only one piece of the payment, and it is rarely the piece that decides whether you should buy.

Let's look at what was really going on then, what is different now, and what a first-time home buyer should be watching instead.

What the economy looked like in 1981

Inflation was running in the double digits, several times what we consider normal. To break it, interest rates had to climb, and mortgage rates went with them. Most borrowers in that stretch saw rates between 13% and 17%. In October 1981 the average 30-year rate peaked above 18%.

Jobs were under pressure too. Unemployment kept rising through the recession and topped out near 11% the following year.

Two things get lost when people quote that 18% figure. First, the peak was brief. Rates sat at that level for a matter of months. Second, it was a very different economic cycle from the one we are in today.

The real difference is home price compared to income

In 1981, the typical home sold for about $69,000, which was roughly three times a typical household's income.

Today, the national figure is closer to five times income. Here in California, it is common to see eight to ten times income.

That is the heart of it. A lower rate on a much larger loan can produce a heavier payment than a high rate on a small one. When the price is that far ahead of income, the payment takes a bigger bite of the paycheck no matter what the rate says.

The costs that ride on top of the mortgage

The mortgage is only part of the monthly payment. Three other pieces have grown.

• Property taxes. In California, Prop 13 capped the base rate in 1978. Since then, many newer communities have added Mello-Roos, special assessments, and community facilities districts that push the effective rate to 1.5% or 2%. And because home values are so much higher, the dollar amount is higher even when the percentage is fair.

• HOA dues. Planned communities with parks and shared amenities usually come with monthly dues that many 1981 buyers never paid.

• Homeowners insurance. A policy once cost a few hundred dollars a year. Today it runs in the thousands, and premiums have climbed sharply since 2020.

Add principal, interest, taxes, insurance, and dues together, and today's payment looks very different from the one your parents made.

Taxes softened the blow in 1981

In 1981, the standard deduction for a married couple was $3,400. Mortgage interest and property taxes blew past that easily, so nearly every homeowner itemized. Credit card and auto loan interest were deductible too.

That write-off made a high rate feel lower. By my estimate, a 13% mortgage could feel more like 9% after the tax savings.

Today, a married couple's standard deduction is more than $30,000. Many homeowners never itemize, so the mortgage delivers little or no extra tax benefit. The upside is that renters get that large deduction too, without buying anything.

Life looked different, and so did investing

People married younger in 1981, and first-time buyers were younger to match. Both ages have moved up by years. Buying a home still tends to follow the same trigger it always has: a relationship, kids, and the wish to stop moving.

The other shift is choice. In 1981, a home was the core investment for most families. Today you have index funds, ETFs, retirement accounts, and more. Renting while investing elsewhere is a legitimate plan.

So is today harder than 1981?

In my view, yes, a little. Not because of the rate, but because of the price relative to income, plus everything stacked on top of the payment. The gap between then and now is smaller than the headline suggests, and it tilts the other way.

How much house should you buy?

Rate is not the deciding factor. Your budget is. Two rules of thumb help.

1. Housing ratio. Lenders look at your total housing payment, including taxes, insurance, and dues, as a share of gross income. A common target is 28% to 35%.

2. Income multiple. At the higher end of that range, with 20% down, most buyers land at a purchase price around four to four and a half times their household income. If you want more breathing room, stay closer to three and a half.

For example, a couple earning $200,000 a year would be looking at roughly $800,000 to $900,000. That is a starting point, not an approval. Your other debts, down payment, and local taxes all move the number.

Try the practice payment test

Before you buy, find out how the payment feels.

If the payment on the home you want would be $4,000 a month, set aside that full amount every month, on top of your current rent if you can, or the difference at minimum. Do it for as long as you can, ideally up to a year.

If you never need to dip back into that account, you can afford the home, whatever the rate is. If you keep pulling money out, you have your answer, and it cost you nothing. Either way, you end up with more saved.

If you are buying purely as an investment

A home gives you stability. No landlord can call to say they are selling. That is a real reason to buy.

But if the only reason is investment return, talk with a financial advisor about your whole plan. Putting every dollar into one house is not diversification.

The bottom line

Stop fixating on the interest rate. It matters, because it moves the payment, but it is one input. Rates change, and if they fall you may be able to refinance.

Start with a price that fits your income, test the payment against your real budget, and decide from there. And if the math says now is not your time, that is a good outcome too. It lets you put your energy into other ways to build the life you want.
