# Lease Administration & Renewals: done-for-you AI automation by BufferSol

> A done-for-you lease administration and renewals automation is an AI agent that reads your leases, abstracts the key terms and dates into your property management system, and works a calendar of expirations, notice deadlines, rent reviews and insurance renewals. It drafts renewal offers and notices for a manager to approve, sends them, collects e-signatures and updates the record. BufferSol builds, connects and configures it, and it is live in 3 to 6 weeks.

## Every lease date, notice and renewal tracked and acted on before it slips

**Who it is for:** Residential property managers, build-to-rent and multifamily operators, and owners of small commercial portfolios who track lease dates in spreadsheets and find out about expirations and notice deadlines too late.

### Signs you need it
- Lease dates live in a spreadsheet that only one person keeps up to date.
- Renewal offers go out late, or after the tenant has already given notice.
- Terms get changed in emails or portal messages and never make it into a signed document.
- You took on leases through an acquisition and do not know what they say.
- Tenant insurance certificates and compliance documents expire without anyone noticing.

## Business outcomes
- **No missed dates.** Every expiration, notice deadline, rent review, break clause and option date sits on one calendar that triggers work, not just reminders.
- **Renewals sent on time.** Renewal offers go out in your chosen window, priced by your rules and approved by a manager, so fewer tenants leave by default.
- **One source of truth.** Signed terms, amendments and notices sit against the lease record, so nobody relies on memory or message threads.

## How it works today
1. A property manager keeps a spreadsheet of lease end dates and checks it when they remember.
2. Before a renewal, they pull the lease PDF, check the notice clause and look up market rent.
3. They write a renewal letter or rent increase notice by hand, often without a template.
4. Offers, replies and changes go back and forth by email and portal messages.
5. Signed renewals are uploaded to the property management system, and the new rent is keyed in manually.

Hidden costs:
- Leases roll over or end on terms nobody chose because the notice window passed.
- Every unplanned move-out brings vacancy, turn costs and lost rent.
- Informal changes that never get signed lead to disputes over notice, rent and deposits.

## How it works done for you
1. The agent reads existing leases and amendments, abstracts parties, dates, rent, escalations, notice periods and special clauses, and flags anything it is unsure of for review.
2. It writes the abstract to AppFolio, Buildium, Yardi, Rent Manager or MRI and builds a calendar of every critical date.
3. Ahead of each renewal window it drafts an offer using your pricing rules and any local rent rules, and a manager approves or edits it.
4. It sends the offer, answers routine questions from approved content and collects e-signatures through DocuSign or your system's e-sign.
5. It handles replies: renewals are recorded, non-renewals start the move-out and turnover workflow, and disputes go to a person.
6. It tracks expiry dates for tenant insurance and compliance documents and asks for updated copies.
7. Every abstract, notice, approval and signature is logged with a link to the source document.

## What changes for the team
- **Property manager.** Today: Checking spreadsheets, writing renewal letters and chasing signatures. Done for you: Approving offers, handling negotiations and working the cases the agent flags.
- **Lease administrator.** Today: Reading leases line by line to fill in a spreadsheet. Done for you: Reviewing the agent's abstracts and fixing low-confidence fields.
- **Asset manager or owner.** Today: Learning about expirations only when a unit goes vacant. Done for you: Seeing upcoming expirations, renewal status and rent changes across the portfolio.

## KPIs we measure
- **Renewal offers sent on time:** Share of expiring leases that received an offer inside the target window.
- **Renewal rate:** Share of expiring leases renewed, by property, baselined from the last 12 months.
- **Missed critical dates:** Count of notice deadlines or options that passed without action.
- **Abstract accuracy:** Fields corrected in review per lease abstract.
- **Days from offer to signature:** Tracked per renewal from the e-sign log.

## Systems it connects to
AppFolio, Buildium, Yardi, Rent Manager, MRI Software, DocuSign, Google Workspace, Microsoft 365, Excel

## Guardrails
- A manager approves every renewal offer, rent change and notice before it is sent.
- Notices follow the lease and local law, and jurisdiction-specific templates are reviewed by your counsel.
- Low-confidence lease abstracts are flagged for a person to check against the source document.
- Access is limited by role and portfolio, and tenant data stays in your systems.
- A full log of every abstract, notice, approval and signature.

## What teams say about this work
- Landlords describe auto-renewing leases with notice deadlines, plus informal portal messages that changed rent and terms without a signed document, leaving it unclear which terms apply and when the tenancy ends. ([BiggerPockets Forums](https://www.biggerpockets.com/forums/52/topics/1317334-what-do-you-do-when-a-tenant-gives-improper-notice))
- Experienced owners advise tracking notice and renewal dates on a calendar and putting every change in signed writing, because disputes over notice periods affect rent owed and deposits. ([BiggerPockets Forums](https://www.biggerpockets.com/forums/52/topics/1317334-what-do-you-do-when-a-tenant-gives-improper-notice))
- Owners who inherit or buy occupied rentals often cannot find a current signed lease, so rent, notice rules and responsibilities are unclear. ([BiggerPockets Forums](https://www.biggerpockets.com/forums/52/topics/1317371-inherited-a-rental-with-tenant-but-no-lease))
- Landlords point out that vacancy and turnover cost more than most repairs, and that the lost rent is easy to overlook because it never appears as an expense. ([BiggerPockets Forums](https://www.biggerpockets.com/forums/52/topics/1317345-turnover-and-vacancy-cost-more-than-repairs-how-we-think-about-it))
- Reviewers of a property management platform note it lacks templates for rent increase letters, leaving managers to write renewal notices by hand. ([Trustpilot](https://www.trustpilot.com/review/rentmanager.com))

## Frequently asked questions
### Can it read old and scanned leases?
Yes. The agent reads digital and scanned leases and amendments with document AI and abstracts the terms into structured fields. Each field links back to the clause it came from, and anything unclear or low-confidence is flagged for a person to check. For acquisitions, this shows the key dates and clauses across the whole rent roll without reading every lease by hand first.

### Does it set the renewal rent?
It proposes, and a person decides. The agent drafts an offer using the pricing rules you give it, such as a market rent source and any caps or rent stabilization rules that apply. A manager approves or edits every offer before it is sent. The agent never sends a notice or a rent change without that approval, and each approval is logged.

### Is it only for residential leases?
It works for residential portfolios and smaller commercial portfolios. For commercial leases it tracks items such as break clauses, options, escalations, CAM reconciliations and insurance requirements. Complex legal interpretation stays with your lease administrator or counsel; the agent's job is to make sure the right date and clause reach the right person in time to act.

### How long does setup take?
It is live in 3 to 6 weeks. We start by abstracting a sample of your leases and agreeing fields, date rules and templates with you. Then we abstract the full set, connect your property management system and e-sign, and run the renewal calendar with a manager approving every action before we hand over day-to-day running.

### What does it cost?
It depends on the number of leases, how many need abstracting from scans, the systems involved and whether commercial terms are in scope. We go through your portfolio on a short scoping call and then send a fixed written quote. We do not post prices because portfolios differ so much; the quote is sent after that call.
