A building has costs that belong to no single tenant: security guards, the generator, water tanks, cleaning, lift maintenance, repairs to common areas. Someone has to decide who pays for them. If the costs are lumped together, owners argue and buildings look more or less profitable than they are. This guide explains how to record shared costs and split them fairly between buildings and owners.
Three kinds of building expense
| Kind | Who bears it | Example |
|---|---|---|
| Building cost | The building or the manager's portfolio | Security guard for one tower |
| Owner cost | A specific owner, to be deducted from their payout | Repairs inside one owner's apartment |
| Shared cost | Several buildings or owners, split between them | A manager's office that looks after four buildings |
The first step is to classify every expense when it is entered. If this is left until month end, the answer is usually guesswork.
Tag every expense with where it belongs
Each expense should record:
the building, the apartment, if it relates to one, the category (repairs, security, utilities, salaries), the date and the document that supports it, and who bears it. Splitting a shared cost
When one cost serves several buildings, split it on a basis you can explain.
| Basis | When it fits |
|---|---|
| Equal shares | Costs that do not depend on size |
| By number of apartments | Staff, management time |
| By floor area | Cleaning, common-area repairs |
| By fixed amounts you agree | Special arrangements |
| By percentage | When shares are already agreed |
Example: a Rs 120,000 security contract covers three buildings, split by number of apartments.
Building Apartments Share Amount (Rs) Tower A 40 50% 60,000
| Tower B | 24 | 30% | 36,000 |
|---|---|---|---|
| Tower C | 16 | 20% | 24,000 |
| Total | 80 | 100% | 120,000 |
The total must always equal the original expense. If the shares add up to 99 or 101 percent, something is wrong.
Recurring expenses
Many costs repeat each month: guard salaries, internet, cleaning contracts. Set them up once as recurring, then generate them each month, and check the amounts. This avoids forgetting a month and makes the cost trend easy to see.
Charging an expense to an owner
If a repair is the owner's responsibility, it should reduce their payout. Record it against the apartment, so the right owner is found, and mark the expense category as owner-chargeable. Then the owner's statement shows the repair and the manager has a clear basis to deduct it. See how to calculate an owner's payout.
What to check each month Does every expense have a building? Do the allocations add up to the expense? Are owner-chargeable expenses linked to the right apartment? Are recurring expenses all generated? Does the paid-from account (bank or cash) match the actual payment? Reports that use the tags
With expenses tagged, you can see:
the cost of running each building, expenses by category and by month, income against expenses, building by building.
Compare collection against expenses each month, to see whether a building is paying its way.
Common mistakes One big "maintenance" bucket. You cannot see which building costs the most. Shares that do not add up. The split is wrong by a few thousand rupees. Charging the owner without a document. The owner disputes it. Forgetting recurring costs. The month's profit is overstated. Paying expenses from the wrong account. The cash book and bank do not agree. How OneAccounts Property Management does it
Every expense is posted to the accounts when it is entered, with the account it was paid from. An expense can be split across buildings by percentage or by fixed amounts,. Monthly recurring expenses can be generated each month. A category that is charged to an owner requires you to select the apartment, so the correct owner is found automatically, and the amount is netted off when you pay that owner. Expenses can be searched by building and apartment. See OneAccounts Property Management.
Frequently asked questions How do I decide the basis for splitting a cost?
Choose the one that best reflects how each building uses the service, write it down and apply it consistently.
Who pays for repairs in a rented apartment?
That depends on the tenancy agreement and your agreement with the owner. Record who bears each repair at the time.
Should recurring expenses be entered each month by hand?
Set them up once and generate them. Check the amounts monthly.
Can one expense be shared between owners?
Yes, by allocating it in agreed shares. The shares must total the expense.
Is a manager's salary a building cost?
Often it is shared across buildings. Split it on an agreed basis.
