Closing is the end of the transaction and the beginning of operating the property. The first three months are the best time to document what you own, understand what is due and build a repeatable maintenance rhythm before the first surprise forces the issue.
Start with information, not projects. Record the major systems, approximate ages where known, model/serial information where useful, shutoffs, filters, service records and any unresolved items from the purchase process. Identify the professionals you would call for heating, plumbing, electrical, roofing and urgent water issues before you need them.
Turn the invisible list into dates. Heating and cooling service, filters, gutters, exterior drainage, smoke/CO alarm routines, well/septic items where applicable, generator service and other property-specific needs belong on a repeatable schedule rather than in memory.
Not every old system needs replacement, and age alone does not predict failure. But known ages, service history and condition observations should inform a 1 / 3 / 5 / 10-year planning horizon so a future replacement is a budget decision instead of a surprise.
Keep invoices, warranties, service notes, contractor information, photos and major decisions tied to the property. A good record gets more valuable each year because future decisions have context.
