Maintenance and repairs — the work that actually preserves the asset.

Rental properties decay on a schedule. HVAC lasts 12 to 18 years, roofs 20 to 25, water heaters 8 to 12. You can ignore that schedule and flatter your cash flow for a while, or you can budget for it and stop being surprised. This guide is about the rhythm of ownership — when to inspect, when to replace, and how to build a vendor bench before you need one at 9pm.

Section oneThe make-ready between tenants

The 7 to 14 days between tenants is the one uninterrupted window you get to actually see the unit. Walk it with a checklist: paint touch-ups, deep clean, appliance check, smoke and CO detectors, HVAC filter, water pressure, every door and window, every outlet. Fixing ten small things now costs a fraction of fixing them reactively after the next tenant moves in. The shortest path to a fast re-lease is a unit that photographs well and shows fresh.

Section twoEmergency vs. routine

Emergencies are anything that threatens safety, habitability, or causes active damage — burst pipe, no heat in winter, roof leak, electrical smell. These need same-day vendor response and a willingness to spend whatever it takes to stop the damage. Routine maintenance is everything else: leaky faucet, appliance repair, cosmetic drywall. Batch routine items into scheduled visits; don't run to the property for each one. The line between the two is where new landlords overspend.

You don't decide when things break. You only decide whether you're ready.

Section threeThe 50% rule and what it really covers

The classic 50% rule says operating expenses plus vacancy average half of gross rent over time. That's maintenance, taxes, insurance, property management, turnover, and vacancy combined — not just maintenance. In practice, maintenance alone usually runs 10–15% of gross rent on a well-kept property, higher on older buildings or deferred-maintenance buys. Budget for it monthly, even in months nothing breaks, because the replacements come in clusters and blow up any month you didn't reserve.

Section fourBuilding a vendor bench

You need five vendors before you need any of them: a plumber, an HVAC tech, an electrician, a general handyman for small jobs, and a cleaner who can do the make-ready. Collect names, pay a few invoices to build rapport, and ask each one who they trust in the other trades. The first 9pm burst pipe is a terrible time to find a plumber cold; the one you already paid last year picks up the phone.

Section fiveRepair vs. improvement, the tax line

The IRS treats repairs as immediately deductible and improvements as depreciated over 27.5 years. Fixing a leaky faucet is a repair. Replacing the entire kitchen sink and cabinets is an improvement. The line matters because a $12,000 improvement gives you $436 in deductions this year instead of the full amount you'd get from a repair. Keep receipts that identify the work done — not just the dollar amount — so your accountant can code it correctly.
