What Should Landlords Put in Writing? A Record-Keeping Discipline
Most landlord-tenant disputes don’t start with bad faith. They start with memory. Both sides remember the same conversation differently: “I said I’d handle that repair”, “nobody told me that”, “we already agreed”. Nobody may be lying. But without a record, who’s right is simply undecidable.
The fix isn’t complicated: some topics should never live only in a phone call. Here’s which ones, and how to write them.
The 7 topics that must be in writing
1. Rent increases. The percentage, the new amount, and the month it takes effect. A verbal agreement gets remembered differently on payment day.
2. Payment-date changes and late payments. “I’ll pay on the 10th this month” belongs in writing; otherwise it becomes a habit and the boundary turns negotiable.
3. Repairs and who pays. Who does the work, who pays, is it deducted from rent? This is the single most argued-about topic. Nothing should start before the amount and method are written.
4. Inventory and appliance condition. Photographed records at move-in and move-out. That’s exactly what the move-in inventory checklist is for.
5. Renewal or notice to vacate. Date and intent, stated plainly. A verbal “I’ll probably stay” is neither a renewal nor a notice.
6. Requests to enter the property. Viewings, inspections, repairs — when, who’s coming, and consent. This is both courtesy and evidence.
7. Deposit return. How much was returned, how much withheld, and what each deduction is based on — line by line.
How to write it: 4 rules
- Short, one topic per message. Mixed messages get remembered selectively.
- Exact dates and numbers. Not “next week” but “August 5”; not “a small discount” but “$50”.
- Ask for confirmation. “If you agree, can you reply ‘confirmed’?” — a one-word reply becomes your record.
- Stay on one channel. Don’t finish a text-message topic on a phone call; if you do, write the summary back into the same thread.
Three templates — copy, change the numbers
What delays the writing usually isn’t laziness. It’s not finding the sentence: too formal reads hostile, too casual carries no weight. Three templates, for three situations, that are neither:
Rent increase notice:
Hi [name], our renewal window is coming up. From [month] the rent will be [new amount] (currently [old amount], increase basis as per our lease). If that works, just reply “confirmed” — happy to talk if you have questions.
Repair agreement (before work starts):
Hi [name], summary of the [job] we discussed: [who] arranges the work, cost [amount], [deducted / not deducted] from rent, invoice stays with [whom]. If that’s what we agreed, could you reply “confirmed”? Work starts after your reply.
Post-call summary (with an objection window):
Hi [name], summary of what we just agreed on the phone: [point by point]. If anything is missing or you remember it differently, reply by this evening; otherwise I’ll treat this summary as agreed by both of us.
All three share the same skeleton: situation, number, date, and a one-question close.
The last line of the third template is the most useful technique in this article: the objection window. You don’t chase a confirmation — you set a reasonable deadline and treat silence as acceptance. Even against a tenant who never replies “confirmed” but never objects either, your position is strong: the record isn’t a one-sided claim, it’s an unanswered summary.
If you’re a letting agent: the correspondence is three-way, not two-way
For anyone managing a portfolio, the same discipline gains a dimension: there’s an owner in the picture. And the most expensive mix-up is the conversation with the tenant that never gets written to the owner. A repair cost deducted from the payout that the owner first discovers on the statement, so the conversation now happens on the defensive.
The arrangement fits in a three-row table:
| Topic | To the tenant | To the owner |
|---|---|---|
| Repairs (needing approval) | agreement before work starts | approval before work starts — amount and whose side it comes off |
| Rent increase | notice | basis and new amount, before it’s applied |
| Late / short payment | reminder | short note the same day — no surprise statements |
And once a month, one summary message per owner: collected, paid out, deducted, notes. Four lines. That single habit removes most of the “why is the payout short” phone calls, because the answer was written before the question. The ledger side of the collected-vs-paid-out split is in the printable rent ledger.
Which channel for which topic
After “put it in writing” comes the second question: where? Three layers, and what matters is not mixing up their weights:
- Messaging (WhatsApp, texts): the day-to-day layer: payment reminders, repair appointments, call summaries. Fast, dated, two-sided; the templates above live here.
- Email: the layer for agreements carrying amounts and dates: increase notices, cost splits, renewal intent. What sets it apart is the archive: searchable years later, and it doesn’t vanish with a phone.
- Formal notice (registered mail, notary where applicable): the layer for notices with legal consequences. What decides you need it isn’t the content but the consequence: if you’ll rely on it to exercise a right, check the required method with a local professional.
The common mistake isn’t dragging a layer-one topic up to layer three. It’s the reverse: leaving a layer-three notice in a chat thread. A message trail is strong for everyday agreements and weak, on its own, for anything with formal requirements.
There’s also the move-out period, when correspondence intensifies and narrows to one topic: the deposit. That period needs its own written checklist — I laid it out in the move-out inspection checklist, and what can be deducted from a deposit separately.
Where to keep it
Messages that live only on a phone disappear when the phone does. A durable setup has three parts: filing per property, records with dates, and photographed documents.
RentMind keeps all of it under the property: rent and payment records, lease dates, inventory and expense notes in one place, with reminders before rent day and lease expiry. So the record of the conversation and the tracking of the date sit on the same screen. If you’re managing from another city it matters even more — as I wrote in managing a rental from another city, at a distance the record is your only truth.
When it’s already heated: writing as de-escalation
The least known use of written communication is what it does after an argument breaks out. A phone call that got loud, followed by one calm message the same day, does three jobs at once: it puts the matter on record, lowers the temperature, and forces both sides to choose their sentences. The pattern has three parts — acknowledge + facts + proposal: “Things got tense between us, and I don’t want that (acknowledge). The boiler fault was reported on the 12th; the engineer could come on the 15th (facts — dates, no interpretation). Here’s what I propose going forward: … (proposal).” A single line of blame breaks the pattern; facts go in with their dates and without adjectives.
The message’s goal isn’t to be right — it’s to put the relationship back on the written track. From there, everything runs on the system of the seven topics above.
Being formal isn’t being cold
Many landlords avoid writing things down so as not to seem distrustful. In practice the opposite happens: relationships with clear written terms have fewer arguments, because both sides know where they stand. A good tenant isn’t bothered by written records — the tenant who is bothered is usually the one who’ll cause trouble later.
Two small habits soften the tone. First, say why, once — a single sentence at the start of the tenancy: “Anything we discuss involving money or dates, I’ll also summarise by message, so we both have a record.” After that, no explanation is needed. Second, write the good news too: a landlord whose messages are only increases and reminders reads cold; “deposit returned in full, thank you” goes into the same archive and turns the habit from a collection tool into a shared record.
Frequently Asked Questions
Is a text message enough? For day-to-day matters it’s practical and widely accepted. But formal notices — rent increases, termination, anything tied to the lease — may carry legal form and timing requirements in your jurisdiction. For those, check the required method with a local professional.
What if the tenant refuses to communicate in writing? Write anyway: after the call, send a summary: “today we discussed X and agreed to Y.” If they don’t object, that record becomes meaningful support over time.
Do I need to write down every small thing? No. The test: write it down if money, a date, or the condition of the property changes. “Is the boiler working?” doesn’t need a record. “I’ll replace the boiler, $600, not deducted from rent” does.
Does the record help if the tenant never replies “confirmed”? It does — with the objection window technique: end the summary with “if you remember it differently, reply by this evening.” An unanswered summary isn’t a one-sided claim; it’s a record that was open to objection and received none.
I’m a letting agent — how should I organise correspondence with owners? Two rules: any cost needing approval is written to the owner before work starts (amount plus whose side it comes off), and once a month each owner gets one summary message — collected, paid out, deducted, notes. Surprise statements are the fastest way to lose an owner’s trust.
