Fair request. You are an actuary, so let me make the case in your language rather than mine, because the usual pitch will not land on you and twenty answers above have not tried. Your sample size is the problem. You will transact real estate maybe five to eight times in your life, roughly once a decade. You cannot calibrate on that. Everything you know about how a deal goes comes from a handful of observations, most of them from a different rate environment and a different set of rules. A working agent sees dozens a year and thousands over a career. This is not a claim about intelligence. It is a claim about n. The distribution is what should worry you, not the mean. You are almost certainly right that you can handle the median transaction. Find house, make offer, get inspection, close. That is not hard and you would do it competently. But the value in representation is not in the median outcome, it is in the tail: the undisclosed lien, the encroachment that surfaces at survey, the appraisal that comes in 40,000 short with your contingency already removed, the seller who quietly has two offers, the title defect from a 1997 divorce. Those are low probability and high severity, and low probability high severity is precisely the class of risk where people who transact rarely make expensive mistakes. You price this kind of thing professionally. You know that expected value is not the same as acceptable exposure on a single draw. There is an adverse selection problem too. The information asymmetry does not run in your favor. The listing agent knows how long the property sat, what fell out of the last escrow, what the seller's real motivation is, and what the neighboring properties actually closed at net of concessions. Some of that is public, most of it is not. Unrepresented, you are on the wrong side of that trade with no way to price it. Now the counterargument, honestly. There are conditions where you should represent yourself. If you are buying new construction from a builder, if you have done several transactions in the same market recently, or if the deal is simple and you are paying cash, the value of representation drops substantially. And since the 2024 industry settlement, buyer broker compensation is negotiable and no longer advertised in the MLS, which means it is now a real line item you are choosing to pay rather than something built into the price. That is a legitimate reason to scrutinize it. So my actual answer is not hire an agent. It is: decide what you are buying. If you want someone to open doors, that is not worth much and you should negotiate accordingly. If you want someone whose job is to find the failure modes before you sign, interview for that specifically. Ask candidates to describe the last three deals that went sideways on them and what they did. That question will separate them faster than anything else. I am Zoltan Peresztegi, a real estate professional serving the South Bay and greater Los Angeles. Your wife is not wrong, but you are entitled to a better argument than the one you have been getting, and you should hire on the tail risk, not on the door opening. Zoltan
