For property managers, the last few months of the year bring two kinds of deadlines at the same time. Buildings need to be prepared for cold weather before the first freeze. At the same time, the books need to be in order for the December close, and vendor tax forms are due soon after the new year begins.
These tasks draw on the same team, the same vendors and the same owner relationships. When they are handled together, the season is far easier to manage. When they are handled one at a time, things tend to slip, and the cost usually shows up in January.
Our pre-winter property checklist is a concise reference to help you prepare. If your winter preparation is already underway, the guide can help you perform a quick review of anything that may have been missed.
Building Systems: Book Early
Heating is the first priority. HVAC systems and boilers should be serviced before the first cold snap. Once temperatures drop, contractors fill their calendars quickly, and emergency calls take priority over routine visits. A service appointment that slips in October can easily turn into a wait of several weeks.
Roofs, gutters and drains belong on the same schedule. Blocked gutters and drains are a common cause of ice buildup and water damage, and clearing them in the fall costs far less than repairing a ceiling in February.
Snow and ice removal also deserves a close look. A signed contract is a good start, but it should state two things in writing: the snowfall depth that triggers service, and how quickly the contractor will respond once that depth is reached. Without those terms, it can be hard to settle a disagreement about whether a contractor should have been on site, and an icy walkway can quickly become a liability concern for both the manager and the owner.
Owners: Agree on Costs Up Front
Winter work often involves spending that owners did not plan for. Sharing the planned work and its estimated cost ahead of time, and getting approval before it starts, keeps the conversation about planning instead of about an unexpected bill.
It is just as important to confirm each owner's emergency repair spending limit before the season begins. A burst pipe in the middle of the night is not the time to find out how much you are authorized to spend. Limits vary from owner to owner and from one management agreement to the next, so it is worth confirming them property by property.
Vendor Paperwork: Do it Now, Not in January
Every vendor working on your properties should have a current certificate of insurance on file, naming both the owner and your company as additional insured. Workers' compensation certificates should be checked at the same time. Winter work, such as roof access and snow removal, carries more risk than most jobs, and an injury involving an uninsured contractor can lead to a claim against the property.
The other key item is a W-9 for every vendor you have paid this year. Form 1099-NEC is due by January 31, and tracking down missing W-9s after the holidays is much harder than collecting them now, while vendors are still on site and still being paid.
Tenants: Set Expectations Early
Cold-weather procedures should reach tenants before the first cold night, not after. These usually explain how to report a loss of heat, what to do if a pipe freezes and simple steps like keeping the thermostat at a minimum setting when a unit is empty.
It also helps to give tenants one clear channel for maintenance requests. When heating calls arrive as text messages to someone's personal phone, they are easy to miss and hard to hand off between staff, and they leave no record if a question comes up later. When every request is logged in one place, each one has a time stamp, an assigned person and a clear status.
Year-End: Reconcile Before the Close
The last item on the checklist is financial. All 2026 vendor invoices should be coded, and payments reconciled by property, before the December close. Small coding errors may not seem important in any single month, but over a full year, they add up and appear in owner statements, where they are harder to explain and slower to fix. Finishing this work in December gives owners accurate year-end reports and gives your team a clean start to the new year.
Why One System Makes the Difference
Most of the items on this checklist depend on information that, for many management companies, is stored in different places. Vendor documents sit in email inboxes. Maintenance requests come in by phone and text. Owner approvals are spread across email threads, and invoices live in the accounting system. Every time information moves from one place to another, something can be missed.
SS&C Skyline brings all of this together in one system, alongside your accounting. Each vendor has a single record that holds work orders, bills, insurance and 1099 and W-9 details, and vendors can upload their own documents through the vendor portal. Tenants submit maintenance requests through the tenant portal, and your team can track each one to completion across every property. Owners can view their statements and expenses in the Owner Portal without your team preparing extra reports. Because everything sits in the same system as your books, the year-end close draws on the same records your team has been using all year.
