I once lost a $1,400 repair to a tenant's text message alone: "Water coming from somewhere upstairs." The "somewhere" cost me four days, a plumber, and a drywall guy, all because I hadn't walked the house since spring. That's the whole argument for a maintenance calendar, compressed into one expensive week. Not a spreadsheet you fill in once and forget, but a rhythm you run every year so the same problem never catches you off guard twice.
Here's the promise. By the end of this you'll have a season-by-season version of that rhythm, the three numbers that separate a real contractor from a smooth talker, and a short list of tasks that cost almost nothing in March and cost thousands by August. You already know how to spot a good tenant. This is how you keep the house worth renting to them next year.
I own two rentals now and I count the calendar as part of the business. When a past owner handed me a box of paint cans and said "good luck," I didn't know that roof checks, filters, and one honest handshake with an insulation installation new Braunfels crew would save me more money than any rent increase ever has. Start with the attic air sealing and you're already ahead of half the landlords on your street.
Who actually owns each task?
Before the seasons, get the split right, or you'll spend every summer arguing about air filters.
Item | Landlord | Tenant |
HVAC filters | Supply the first set | Swap monthly |
Lawn and sprinklers | Repair the system | Run and report |
Smoke detector batteries | Test at every turnover | Report chirps |
Shower leaks and slow drains | Fix fast | Tell you same day |
Write it into the lease. A tenant who knows you'll handle the water heater but expects them to swap a ten dollar filter is a better tenant, not because they're nicer, but because neither of you is guessing. That framing came from a property manager I hired once who handed me a two page version of this table on day one.
Spring: cheap fixes, big savings
March and April are your gift. You have a paid tenant, you have mild weather, and every small repair costs the least right now.
- Walk the roof with binoculars from the driveway. You don't need to get on it. Look for lifted shingles and any spot where a branch is touching.
- Check the attic for daylight and dark stains. Both are stories about money you're about to spend.
- Flush the water heater, or pay someone to. Sediment is a slow tax on every shower your tenant takes, and a drain takes an hour.
- Test the irrigation. A stuck valve in July is a surprise water bill and an angry call.
- Re-caulk around tubs and showers. It's maybe a fifteen dollar tube and an afternoon, and it's the difference between a clean repair and a rotted subfloor.
If your attic insulation is matted, torn, or missing patches from old plumbing work, spring is the moment to fix it. According to the Department of Energy, most attics in this climate need more insulation than builders installed, and the payback shows up in every utility bill the tenant pays on their own dime.
Summer: the season that punishes you
July and August are when good prep becomes a boring phone. That's the goal. You want a summer where your phone does not ring, because the AC runs and the tenant pays a bill they can live with.
The two things that ring a phone in August are cooling failures and pests. Have the AC serviced in May, before the technician's truck is booked solid. Watch for ants at the slab edge and roaches in the kitchen at the October turnover, because the summer colony has been quietly growing under your foundation since June. It sounds small, but a pest problem reported twice becomes a pest problem you pay for twice.
This is also the season to check your exterior weather stripping and door sweeps. A quarter inch gap on one entry door can push cooling costs up and leave a tenant convinced the AC is failing when it's working fine. New weather stripping is a five dollar fix and an instant cooling improvement.
Fall: the maintenance you can't skip in Texas
October is attic inspection season in the Hill Country, and it matters more than most landlords realize. Temperatures swing hard in one day, and every unprotected pipe run, draft, and crack in your attic is now visible as a cold spot. This pass is where you separate the houses that make it to spring untouched from the ones that spend February paying for burst pipes.
Walk your own attic with a flashlight before the first freeze, and specifically check the runs that go near exterior walls. This is where I first noticed thin spots under a disconnected duct work, which led to the air sealing project that finally stopped the dusty attic smell in the hallway. A pro can help you spot what a flashlight can't, and New Braunfels insulation installation crews are usually booking for fall by the middle of September, so call early enough to get on the schedule before the crush.
Two more fall items on the property side: have the gutters cleaned before the leaves fall, and have a roofer look at any tabs that lifted in the summer storms. Your insurance company prefers a documented repair to a frozen claim, and you'll have a receipt to prove the house was looked after.
Winter: protect, document, reset
Winter in Texas is short but not soft. Every few years a hard freeze hits, and entire neighborhoods learn overnight which of their pipes are wrapped and which aren't.
- Wrap exposed pipes in the attic and along exterior walls
- Show the tenant where the water cutoff lives, and write it into the move in checklist
- Photograph everything before the cold snap, repairs included, so your records match the reality
- Re-check the water heater and the AC returns after any repair so nothing is left loose
- Add the tenant's winter reminders to your own calendar, not just theirs
The Environmental Protection Agency points to indoor air quality as one of the biggest reasons for tenant complaints in older homes, which is why I check vents and filters on the same trip as the pipe wrap. Two tasks, one walk. That's how a calendar actually survives a busy year.
How to interview a contractor without getting burned
Ask three questions and you'll learn plenty.
- What's your license number and who carries the liability insurance? A real contractor answers in one sentence.
- What does the written scope say, in square feet and materials, before anyone touches the house?
- Who's on the crew, and who handles damage control if something breaks? You need an actual name.
The Department of Housing and Urban Development treats healthy housing as part of the landlord's basic duty, and that starts with a contractor who documents their work. The [X] I once used for a blown in job gave me a verbal quote and nothing else. The next one I hired brought a written scope, a photo of the equipment, and a phone number for the crew chief. Guess which one I called back the following year.
A quick practical filter: any proposal that starts with tearing out all the old insulation and ends with a number over your annual repair budget should get a second estimate. Good work is boring. It has a document, a date, and a person attached to it.
Where this pays you back
A calendar is not a chore list, it is a rent protection device. When your house is dry, pest free, and cheap to heat and cool, your tenants stay longer, your turnover costs drop, and your vacancy between leases shrinks. Those are the three numbers that decide whether the rental is really an investment or just a second job with a mortgage attached.
Pick one season to start. If you start with fall, you'll go into the next summer with an attic that's actually working for you instead of against your tenant's budget. Your first call is a walkthrough, not a repair. Set that date this week and you'll be ahead of the next cold snap, the next heat wave, and the next tenant who texts you a mystery with a price tag.
