How to split shared expenses across properties
4 min read
One of the quiet ways per-property numbers go wrong: a shared bill gets dumped onto a single property. Here's how to split shared costs cleanly.
Why splitting matters
If a $1,200 blanket insurance policy covers three buildings but you post it all to one, that property looks unprofitable and the others look better than they are. Multiply that across a year of shared bills and your per-property picture is fiction.
Accurate splits are what make a per-property P&L worth trusting — for your own decisions and for owner statements.
Choose a split method and be consistent
Common methods: split by amount you specify, evenly across properties, or by a driver like unit count or square footage. Whatever you choose, apply it consistently so trends stay comparable month to month.
For most landlords, splitting by a specific dollar amount per property is the clearest and easiest to defend.
Do it at entry, not at tax time
The trap is entering shared bills as a lump and 'sorting it out later.' Later never has the context. Split the bill when you enter it, while you remember what it covered.
In Rentwelly you enter a shared bill once and split it across properties by amount; each property's P&L automatically reflects only its share, with the split visible on every report.
