A lease renewal letter to a tenant should make the proposed term, rent and next step easy to find. Start with approved renewal details for that household, identify the property and current lease, and explain how the resident can ask questions or respond.
The preparation matters as much as the wording. A polished letter with the wrong unit, dates or rent is still the wrong offer. The worksheet and sample below help you carry approved details from your records into the letter without losing track of which terms belong to whom.
This guide covers preparing a renewal offer. Use the agreement and any required notices appropriate to the tenancy; do not assume that a sample letter completes that paperwork or determines what happens if a resident does not respond.
Confirm the offer before writing the letter#
Open the current lease and the approved renewal terms together. Buildium's renewal-letter guidance (opens in new tab) identifies the resident, property, existing lease expiration, proposed term, rent and response instructions as core information. Use those categories as a starting point, then verify the values against your own records.
For each household, record the following in a preparation worksheet:
- Recipient and property: the intended recipient names, rental address and unit, plus the mailing address if different.
- Current agreement: the lease reference you use internally and its recorded end date.
- Proposed term: the approved start and end dates, written out rather than shortened to an ambiguous numeric date.
- Proposed rent: the approved amount and payment frequency. Keep this separate from the current amount.
- Other proposed changes: the wording approved for this offer, or a reference to the accompanying documents that explain them.
- Response instructions: the contact person or channel, what response you are asking for, and any approved requested response date.
- Source and review: where the values came from, who approved them, and which letter version uses them.
Keep the source and review notes in your internal worksheet. They help you check the letter but do not belong in the resident's copy.
If the amount, dates or instructions are still being discussed, hold that letter while you resolve them. Do not let last year's letter fill the gaps by default. A requested response date also needs its own review; copying one from another household is not a reliable way to choose it.
Copy and adapt this renewal offer#
Replace every bracketed field. The sample asks the resident to discuss the offer and explains the paperwork step. Adapt those instructions to your approved process rather than adding a signature line or acceptance statement whose effect you have not checked.
[Letter date]
[Resident name or names]
[Mailing address]
Subject: Renewal offer for [rental address and unit]
Dear [resident name or names],
We would like to offer you a renewal for [rental address and unit]. Our records show that your current lease ends on [current lease end date].
The proposed renewal term is [proposed start date] through [proposed end date], with rent of [approved amount] per [payment period].
[Describe any other approved proposed changes, or identify the accompanying documents that set them out.]
Please contact [name or team] at [verified contact method] to discuss the offer or let us know whether you would like to proceed. [Include an approved requested response date, if applicable.]
[Explain how the resident will receive and review the appropriate renewal paperwork, or identify the paperwork enclosed.]
If any of the details above differ from your records, please let us know so we can review them with you.
Thank you,
[Sender name and role]
[Management company, if applicable]
[Verified contact details]
Do not leave the instructions in the finished letter. Read it as a resident would: can you identify the property, proposed dates, rent and person to contact without checking another message?
Avoid adding “all other terms remain unchanged” unless that statement has actually been confirmed for the offer. Similarly, mention an enclosure only when the correct document will accompany this recipient's letter.
Keep the offer and the agreement organized#
Your offer letter and the paperwork used to document the renewal have different preparation jobs. The letter communicates what you are proposing and the next action. Keep the approved agreement or amendment in the same review process so the documents do not contradict each other.
Compare the resident names, property, dates, amount and proposed changes across the whole packet. A correct cover letter does not fix an outdated attachment. If the approved offer changes during a conversation, update the working version and recheck the accompanying documents before sending again.
This is an operational distinction, not a statement about whether a particular letter is legally binding. Use the review appropriate to your tenancy. If the proposal includes a rent change, check separately whether additional notice is required; this sample is not a rent-increase notice. It is also not a nonrenewal or move-out notice.
Prepare different offers from a roster#
When several households receive the same basic letter with different terms, separate the shared wording from the recipient-specific values. The salutation, property reference, dates and rent are candidates for fields. Internal approval notes stay outside the mailing file.
In Postmarkr, a personalized batch uses a letter template and recipient CSV. A shared uploaded PDF keeps the same text for the entire batch. It does not become personalized merely because you import a tenant list. The property mailing hub explains the document choices.
Use a custom CSV column for every personalized template field, with the exact same spelling and capitalization. Keep postal recipient fields separate from custom letter fields. For example, name supplies the postal recipient name, while a separate resident_name column supplies the salutation used inside this template.
A compact field plan is:
resident_name: the approved salutation text.leased_propertyandleased_unit: the property and unit mentioned in the letter.current_lease_end: the date checked against the existing lease.renewal_startandrenewal_end: the approved proposed term.proposed_rent: the approved amount written as you want it displayed.payment_period: the approved frequency, such as the wording used in your offer.
For the envelope, use name, address_line1, address_line2, city, state and zip. Preserve leading zeros in ZIP codes. Keep the rented unit in its custom field even when the mailing address points somewhere else.
Do not paste template-marker text into a PDF and expect it to merge. Create the fields in the letter template, then use the matching CSV headers. Separately prepared PDFs for different households need individual-letter preparation; Bulk Send does not pair different files with roster rows.
Catch a wrong-row error before mailing#
Consider this fictional preparation check. Avery Example rents Linden Court, Unit B; Casey Example rents Unit D. You have approved proposed terms for each household in your source worksheet.
A copied row still says leased_unit: Unit B in Casey's row. The resident name and mailing address are correct, so an envelope check alone would miss the problem. The letter would address Casey while describing Avery's unit.
Trace the prepared letter back through the entire row: resident, property, unit, current end date, proposed dates and rent. Correct the underlying row rather than editing only the preview. Then check whether the same copying mistake affected any other rows.
A preview is a useful comparison point, not a certification that the rest of the list is correct. In a personalized batch, compare the available preview with its source row and review all recipient-specific values in the roster before approving the mailing.
Finish with a record you can follow up from#
Before sending, confirm that placeholders are gone, the current letter version matches the approved offer, and any accompanying documents belong to that household. Choose the delivery method and timing required for your situation rather than deriving them from this example.
Keep the prepared letter, source worksheet, approval record and sending details together. Record the resident's actual response separately from the offer you sent. If there is no response, check the communication and follow-up process appropriate to the tenancy; do not mark the resident as renewed or moving out merely because your requested date passed.
The completed record should let you answer a straightforward question later: what did we offer this household, which details were checked, and what did the resident tell us next?
