Most of your operating costs were decided at the closing table. Real estate is a lobster pot. Easy to swim into, hard to back out of. The upside is the bait. You chase it in, the door shuts behind you, and now you own whatever it costs to run the place. I read a Bisnow panel of Houston operators this week. Insurance, labor, taxes, all turned into deal killers, they said. True. But watch how they talk about it. The cost shows up, and then they go to work. Renovate. Trim R&M and payroll. Survive to next year. I'm old enough to remember the whole industry yelling "survive till '95." Some things don't change. That's the back half of the story. The front half happened before they owned the building. Take labor. Buy a 98-unit deal, and you still have to staff it, a manager and a tech for 98 doors. Buy 212 units in the same town, with a much lower payroll number to run it. One deal drags a heavy payroll line for as long as you own it. The other runs lean from day one. Same work. The math was set before you leased a single unit. It runs down every line. A 1965 building costs more to keep standing than a 2015 build, year after year. Coastal address and your insurance is on another planet. Student housing, you're hiring extra leasing staff. Small market with no employers nearby, try recruiting a maintenance tech without overpaying. A property landscaped in Phoenix rock costs less than one wrapped in grass. Interior hallways and elevators eat money you will never get back. You can't manage your way out of any of it. You bought it that way. And don't assume the heavier cost load comes with the rent to carry it. Sometimes it does. Plenty of times it doesn't. A coastal address can rent for less than an inland one, sitting next to a college or a busy downtown. Cost and rent don't always travel together. Assume they do, and the market corrects you. Once you own it, you get a few levers. The controllable decisions you make, within each expense line, drive most of the results. The rest you just feed. I've fed the expensive kind. You learn it the slow way. Now, we all underwrite the expense line. I'm not saying they don't. The real question is whether you see how the variables are hardwired against you before you sign. You pull up the IRR, and it passes your hurdle rate. But not all IRRs are created equal. Every deal has an expense DNA, and it gets set the day you buy. It's the vintage, the coast, the unit count, the construction, all the things that decide how high your costs start and how hard they swing. Some deals are wired lean. Some are wired heavy and jumpy from day one. Two of them can hand you the very same return. The number won't tell you which. The expense side will. Read it going in. https://lnkd.in/ewuADW2c
