Small portfolio, four doors, been at it about seven years. The first three years my turnover process was basically: clean it, paint whatever looks bad, relist it. Worked fine right up until it didn't.

Stuff I do now that I didn't do then, roughly in order of how much money it's saved me.

Photograph everything, and I mean everything, on the day the old tenant hands the keys back. Not a walkthrough video. Actual stills, close enough to read things. I do the inside of the fridge, the underside of the sink cabinet, the closet floors, the window tracks. Twice now a deposit dispute has ended in about one email because I had a photo with a date on it. The one I lost, back in 2021, I lost because I had a nice general video of the living room and nothing at all of the bedroom carpet.

Write down what's actually in the unit. Model and serial off the water heater, the furnace, the range, the dishwasher, the disposal. I keep it per-unit because I got tired of standing in a basement on the phone with a warranty rep trying to remember whether the Rheem was in unit 2 or unit 4. Took me an embarrassingly long time to figure out that the sticker is usually on the side you can't see and you have to get a phone camera in there sideways.

Check the age of anything with water in it. Water heaters especially. There's a date code in the serial number and every manufacturer does it differently, but it's googleable in thirty seconds. If a heater is at year 11 I'd rather replace it during a vacancy for a scheduled price than at 6pm on a Sunday with a tenant standing in two inches of water. Did that once. Never again.

Run every faucet and flush every toilet and then go look at the ceiling below. Slow leaks show up between tenants because nobody's been using the fixtures, so the drip pattern is fresh and obvious instead of buried under daily use.

And the boring one: I keep a running list per unit of what got fixed and when. Not fancy. It started as a note on my phone. But when the same tenant reports the same disposal jam twice in eight months, that's not a jam, that's a disposal, and I only noticed the pattern because I'd written both down. Before that I was paying a guy $95 to reset the same unit over and over and calling it maintenance.

Curious what's on other people's turnover lists. Specifically whether anyone's found a good way to handle the model-number thing, because mine is still basically a phone note and it shows.

Ours skipped the crawlspace. Wrote "limited access" on the report and moved on. Turned out there was standing water under there and a vapor barrier that had basically dissolved, which we found in February when the floor over it got cold in a way the rest of the house wasn't.

I'm not even that mad about it, inspections are 3 hours and a house is a house. But I've started thinking the report is more of a starting list than a clean bill of health, and I wish somebody had told me that before I read ours and felt reassured.

So what did yours miss. Curious whether it's usually the same handful of things or whether everybody has their own weird one.

Three weeks after we closed, the supply line to the upstairs toilet let go around 6am. I knew the house had a main shutoff somewhere. I did not know where. So I got to spend about four minutes running around the basement in a towel while water came through the kitchen ceiling light fixture.

Found it eventually. Behind a stack of the previous owner's paint cans, painted over at some point, needed pliers to turn. Four minutes doesn't sound like much until it's raining indoors. The plumber figured the delay added maybe $900 to the damage.

So if you closed recently, go find yours tonight. Actually turn it a little, too. A lot of the old gate valves seize open and you find out at the worst moment there is. Ours got swapped for a ball valve, $160, and now it's the one thing in this house whose location I know cold.

While you're down there it's worth knowing where the curb stop is outside, in case the inside valve fails you. Your water utility can tell you where it is. Mine turned out to be under a plastic lid in the front yard I'd mowed over all summer

Was changing the battery in the hallway detector and noticed a date stamped on the back. 2007. Turns out the whole unit expires after about 10 years, not just the battery. The sensor itself wears out and the chirp doesn't tell you that.

So I checked every detector in the house. All five were original to the build. Replaced them all for about $120.

Bonus: the new ones have sealed 10 year batteries, so no more random 3am chirping. Might honestly be the bigger win.

If you haven't checked yours, twist the unit off the mounting bracket. The date is printed right on the back. Takes ten minutes for a whole house. If you have CO detectors, check those too. They only last 5 to 7 years, which surprised me more than the smoke ones.

Wasn't the Sunday project I had planned. That was gutters, still not done. But I'll take it.

For the first year in our place I did home maintenance the way most people do, which is to say whenever something broke or I happened to remember. That's a bad system. I'd suddenly realize the furnace filter was probably three months overdue, or that I hadn't looked at the water heater since we moved in.

So I sat down and spread the boring stuff across the calendar instead of trying to hold it all in my head. Nothing fancy. Roughly what I landed on:

Spring: swap the HVAC to cooling and change the filter, test the AC before the first hot day so a problem shows up on a Tuesday and not during a heat wave, clean the gutters, check exterior caulk and the hose bibs for winter damage.

Summer: check the dryer vent (the outside flap, not just the lint trap), look at the deck or fence, test the sump pump by dumping a bucket of water in the pit.

Fall: furnace on and filter changed before you need heat, reverse the ceiling fans, have the chimney looked at if you use it, disconnect and drain the hoses before the first freeze.

Winter: this is the quiet one. Flush the water heater if you're the flushing type, test every smoke and CO detector, know where your main water shutoff is before a pipe decides to teach you.

Anytime: filters on whatever cadence your system actually needs (ours is every 60-90 days), and write down the date whenever you do something big, because future you will not remember.

The thing that actually helped wasn't the list. It was writing down the date each time I did something, so the next time I could stop guessing whether it had been six months or eighteen. What does everyone else use to keep from forgetting this stuff? Curious whether people go calendar reminders, a whiteboard, an app, or just vibes.

Everyone repeats the "budget 1% of your home's value per year for maintenance" rule. I never trusted it because it's a percentage of the wrong thing; a $400k house and a $250k house can have the identical furnace, roof, and water heater. So I did it the boring way and added up what each major system actually costs to replace and how long it lasts. Rough numbers, national ballpark, adjust for your area:

- Roof (architectural shingle): ~$12,000, lasts ~25 years → ~$480/yr
- HVAC (furnace + AC): ~$9,000, lasts ~15 years → ~$600/yr
- Water heater (tank): ~$1,800, lasts ~10 years → ~$180/yr
- Windows (full set): ~$12,000, lasts ~25 years → ~$480/yr
- Exterior paint / siding upkeep: ~$6,000, every ~8 years → ~$750/yr
- Sump pump, garbage disposal, sump backup: ~$1,200 combined, ~8 years → ~$150/yr
- Deck / driveway / fence upkeep: varies wildly, but budget ~$400/yr
- Appliances (fridge, range, dishwasher, washer, dryer): ~$5,000, ~12 years → ~$420/yr

That lands around $3,400 a year, every year, just to stand still on the big-ticket stuff; before a single "oh no" repair. The trap isn't the total. It's that none of these fail on a schedule you can see, so people treat 12 good years as normal and then eat three replacements in an 18-month window and call it bad luck.

The thing that actually changed how I budget: I stopped thinking in annual percentages and started tracking the install/manufacture date of each system. Once you know your roof is 19 years old and your water heater is 9, the "surprise" mostly disappears; you can see it coming three to five years out and set the money aside. What did I get wrong or leave off your list? Curious what the big one was that blindsided people in year one.

I've been going back through a few years of repair records on my properties and the thing that keeps jumping out is how many of my biggest line items were preventable... not "unlucky," just deferred.

My worst one: a water heater in a rental that let go at year 11. No maintenance ever, no flush, anode rod never checked. The tank itself was $1,600 installed, which I'd budgeted for eventually. What I hadn't budgeted for was the water damage to the unit below it and two nights of the tenant in a hotel. All in, closer to $4,200. A $25 flush once a year and a $30 anode rod at year 6 probably buys you three or four more years out of that tank.

Runner-up: a slow toilet leak a tenant mentioned casually and I mentally filed as "low priority." Three months later it was subfloor work.

So I'm curious what other people's numbers look like:

* ***What's the repair that hurt the most, and what would have prevented it***
* ***Did you actually change anything afterward, or did it just become a story?*** (Genuinely asking; I've had a few "lessons learned" that I clearly didn't learn.)

**For those of you who've gotten disciplined about it, what does your actual system look like?**Spreadsheet, calendar reminders, property management software, a notebook? I'm mostly interested in what people really keep up with, not what they intended to.

Not looking for the "just do maintenance" answer... I know. I'm more interested in the specific failure that finally made it stick for you, and what it cost.

I got curious after a rough couple of years of surprise repairs, so I went back through my records and put real numbers on both sides. Posting in case it helps someone who keeps deferring the boring stuff (which was me).

What a year of preventive maintenance actually costs me:
* HVAC filters (every 3 months): ~$40/year
* Annual HVAC tune-up: $120
* Gutter cleaning (twice a year, DIY): $0, or ~$150-300 if you hire it out
* Water heater flush + anode rod check: ~$25 DIY, $150 if a plumber does it
* Dryer vent cleaning: $25 kit, or $100-150 pro
* Caulk, weatherstripping, misc sealants: ~$50
* Smoke/CO detector batteries: ~$20
Total: roughly $300-800/year depending on how much you DIY.

What skipping it cost me (or nearly cost me), from my own records:
* AC compressor failure after years of never rinsing the condenser coils: $2,400 replacement. The tech told me straight up that annual cleaning likely would have prevented it.
* Small roof leak that sat unnoticed for one winter: $1,800 in drywall, insulation, and repair vs. the ~$150 flashing fix it started as.
* Water heater that failed at year 9 with zero maintenance ever: $1,600 installed. Flushed and maintained units routinely go 12+ years.

That's roughly $5,800 in reactive repairs that a few hundred a year in prevention would mostly have avoided. The industry rule of thumb is that reactive repairs run 3-10x the cost of prevention, and my personal numbers land right in that band.
The unlock for me wasn't motivation, it was just writing things down: what got serviced, when, and what's due next. Half of my failures happened because I genuinely believed "I did that recently" when it had been three years.

Anyone else ever added up their own numbers? Curious whether other people's ratios look similar or if I'm just unlucky.
