How to automate lease renewal reminders

Buildium's own renewal guide lays out a 120-day cycle: use the first month to fix open maintenance issues and get a read on how the tenant feels, present terms at 90 days, aim to finalize by 60, and spend the last 30 on paperwork. The extra month matters, because nobody wants to sign for another year while the dishwasher is still broken.

Two things decide your real start date, and they beat any rule of thumb:

• Your lease's notice clause. If the lease says either side must give 60 days' notice to not renew, a first reminder at 60 days is already too late. Start at least 30 days before the notice window opens.
• Your slow months. You know which months your units sit longest between tenants. For leases ending then, start earlier and think about offering a term that moves the next end date into a busier month.

Here's the schedule I'd build from:

AppFolio. According to AppFolio's renewal feature write-up, you can send renewal letters digitally, give residents up to five term options, have them sign and countersign in the online portal, and trigger a reminder email 7 days before the renewal date. That's a solid base. Seven days out is a last call, though, not a follow-up plan.

Buildium. Buildium has sent bulk renewal offers by email or mail since its 2016 renewals release, and it can renew the lease automatically at term end once the tenant accepts. Its renewal guide says workflow automations can trigger reminders at each stage, and residents can sign in the Resident Center. One catch if you want outside tools to read your lease data: on Buildium's pricing page, Open API access is only on Premium, which starts at $400 a month. E-signatures are $5 a document on Essential, $1 on Growth, and included on Premium.

So before you buy anything, turn on everything you already pay for. Offer at 90 days, portal signing on, every reminder your plan allows. See how far that gets you.

What neither platform does out of the box:

• Text the tenant who ignores email. A tenant who never logs in to the portal never sees the offer.
• Read the reply. "Yes," "we're moving," and "can we talk about the $75 increase?" all land in the same inbox, and the third one is the renewal most at risk.
• Escalate on silence. Nobody gets a task at day 45 saying this unit hasn't decided and the owner should know.

Those three are what's missing. If you're still choosing a platform, the property manager tools roundup compares options. This page assumes you already have one.

A reply to a renewal text is short and falls into a handful of buckets. That's exactly the kind of sorting a small, cheap model does well. Here's how I'd route it:

• "Yes" or "we'll renew." Resend the signing link and say thanks. No person needed until the signature comes back.
• "We're moving out." Log it, confirm the move-out date in writing, start the turnover checklist, and tell the owner the same day.
• A question about rent, terms or repairs. This goes to a person, fast. A tenant asking about the increase is still deciding, and a week of silence decides for them.
• Anything unclear, upset, or legal-sounding. Straight to a person, no AI reply at all.

The line I'd hold: the AI never offers a concession, never changes a rent number, and never promises anything about the unit. Its job is making sure no reply sits unread. The conversation belongs to your leasing manager.

The platforms are heading this way too. AppFolio announced a Realm-X Resident Messenger in October 2025 that answers resident questions about payments, renewals and lease details. It became generally available in June 2026, so if you run AppFolio, see what it handles on your plan before you build around it.

One texting detail: US carriers require anyone texting from a regular 10-digit number through software to register under A2P 10DLC, and unregistered traffic picks up extra carrier fees. The tenant should also have agreed to texts, which is easiest to capture in the lease or the portal.

Start with what a turnover costs. The National Apartment Association's turnover cost breakdown puts a single move-out at $1,000 to $5,000 depending on upgrades, and uses $1,800 as the average in its worked example. That covers lost rent, marketing, screening, cleaning, repairs and planned upgrades. It's a 2016 figure, so swap in your own number if you have it.

I'm in Greenville, so here's the South Carolina version. The South Carolina Residential Landlord and Tenant Act covers it in two sections:

• You consent, it goes month to month. Section 27-40-770(c) says that if the landlord consents to continued occupancy, 27-40-310(d) applies, and that section says a tenancy without a definite term is month to month (week to week for a roomer paying weekly).
• Either side can end it with 30 days' notice. Under 27-40-770(b), a month-to-month tenancy ends with written notice at least thirty days before the termination date in the notice.
• You don't consent, it's a holdover. Under 27-40-770(c), you can bring an action for possession. If the holdover isn't in good faith, you can recover reasonable attorney's fees. If it's a willful violation of the law or the lease, you can also recover up to three months' rent or twice your actual damages, whichever is greater.

Why it matters here: a lapsed lease is a renewal nobody decided on. You lose the increase you planned, and you trade a tenant committed for twelve months for one who can leave on thirty days' notice, often right when the unit is hardest to fill. The day-45 alert exists so that's a choice, not an accident.

This isn't legal advice. It summarizes the statute as published on September 28, 2026. Confirm how it applies to your leases with a South Carolina attorney.

1. Starting inside the notice window. If the lease requires 60 days' notice and your first reminder goes at 60 days, you're already late. Build backward from the lease.

2. Texting people who already signed. The text step has to check the lease status first. Nothing annoys a tenant faster than a "please sign" text the day after they signed.

3. Letting AI answer the rent question. A bot that says "the increase is firm" to someone who was one phone call from renewing just cost you a turnover.

4. No owner in the loop. If the owner hears about a non-renewal on move-out day, you lose the month you could have spent pre-marketing.

Your software's built-in renewals cover it. If offers go out on time and tenants sign in the portal, turn on every reminder and leave it alone.

You counted last year's quiet move-outs and found zero. Then the math says keep your money.

You have a small portfolio and a leasing person who calls everyone. A calendar reminder at day 120 might be the whole system.
