Okay, so William Shakespeare didn't say that. But it's a question a lot of prospective homebuyers are asking today.
Just this week, I got two phone calls in the same day from clients with a problem most people would love to have. “Jimmy, I've got the cash. Should I pay for this house outright or finance it?”
First-world problem? Sure. But it's a real question in an elevated-rate environment, and the answer isn't as obvious as either camp wants you to believe. Dave Ramsey will tell you 100% of foreclosed homes had a mortgage on them. Cute. True. Also not an argument.
So let's make the case for both.
The case for cash
1. No payment is no payment
Zero housing debt dramatically lowers your monthly burn rate. If you're retired or living on a fixed income, that can be more than a math decision. A market that drops 30% while you're pulling money from investments to make a mortgage payment can do serious damage. Advisors call it sequence-of-returns risk. I call it the reason some people pay cash and never look back.
2. Paying cash is a guaranteed return
If your mortgage rate would have been 6.5%, paying cash effectively saves you that interest expense. No volatility. No bad decade. No hoping the market cooperates. That certainty has real value.
3. Cash can win the deal
Cash can make your offer cleaner. No financing contingency. Potentially no appraisal contingency. Faster closing. Fewer moving parts. In a competitive situation, that strength can translate into negotiating power.
4. You sleep at night
Don't discount this one. The “optimal” spreadsheet answer means nothing if carrying a large mortgage makes you anxious or causes you to panic-sell investments during the next downturn. For some people, being debt-free is worth more than squeezing out the highest theoretical return.
The case for financing
Here's the other side. Writing a giant check for a house has a cost too, even if most people don't think about it that way.
1. Home equity doesn't generate a return by itself
Your house appreciates based on the value of the property, not how much equity you have. A $600,000 house that rises 5% gains $30,000 whether you own it free and clear or put 5% down. Same house. Same appreciation. The extra cash you put into the property didn't create additional appreciation. It simply became trapped equity.
2. Your capital stays working
Money you don't hand to the seller can remain invested and continue compounding. Over 10, 15, or 20 years, the future value of several hundred thousand dollars can be substantial. Of course, that only works if you actually keep the money invested.
3. Fixed debt can hedge inflation
With a fixed-rate mortgage, your principal-and-interest payment stays the same while the cost of everything around it generally rises over time. A $3,400 payment may feel very different in 2036 than it does today.
4. Liquid beats illiquid
Pay cash and that money becomes home equity. Need it back later? Now you may need a HELOC or cash-out refinance at whatever rate exists at the time, assuming you still qualify. Job loss. Medical event. Business opportunity. The house won't simply hand your cash back.
5. You can change your mind about the mortgage
Rates fall? Refinance. Want the mortgage gone in five years? Pay it off. Financing preserves options. Once you wire $600,000 to a title company, getting that capital back generally requires another transaction.
6. There may be a tax benefit
Mortgage interest may be deductible depending on your tax situation, but I wouldn't make this the primary reason to borrow. Whether it helps depends on your deductions and individual circumstances. Talk to your CPA before counting on it.
The one question that settles it
Strip everything else away and ask: is the realistic, after-tax, risk-adjusted return you expect on your capital greater than the fixed rate you'd borrow at?
If yes, and you can stomach the volatility, financing becomes compelling. If no, or eliminating the payment materially improves your financial security, cash becomes compelling.
The key word is risk. Your mortgage rate is contractual. Your investment return is not. Comparing a guaranteed 6.5% borrowing cost to an expected 8% investment return is not the same thing as comparing 6.5% to 8%.
The third option nobody tells you about
Here's where it gets interesting. You may not actually have to choose.
Fannie Mae has something called the delayed financing exception.
In certain situations, you can buy the home with cash, take advantage of the strength of a cash offer, and then obtain financing shortly after closing without waiting out the normal cash-out refinance seasoning period.
Cash-offer power going in. Liquidity coming back out.
There are specific guidelines and documentation requirements, so this is something you want to structure correctly from the beginning.
What should you actually do?
- Ask your financial advisor for a realistic after-tax expected return on the money you'd otherwise put into the house.
- Ask me for the actual rate and payment on the mortgage you're considering.
- Run both scenarios over 10 and 20 years.
- Then ask yourself which option gives you the right combination of financial flexibility and peace of mind.
There is no universally right answer. There is only the right answer for your balance sheet, your stage of life, and your temperament.
