Landlords rarely lose money because they set the rent too low. They lose it because they cannot say who paid what, when, and for which month.
The four things to keep straight
- Rent, month by month. Which month each payment covers, not just when it arrived. A tenant who pays on the 28th is paying for next month, and a ledger that only records the date will look like they are always behind.
- The deposit, separately. It is not income. It is held until the tenancy ends, and it should never be mixed into the rent column.
- Water. Meter readings, the rate, and what each tenant owes. A water bill nobody records becomes an argument at the end of the tenancy.
- The condition of the room. What it looked like when they moved in, in photos, with the date.
Why the order matters
A tenant who can see their own record is a tenant who argues less. Most "I already paid that" conversations end in one minute when both sides are looking at the same numbers.
The best time to record a payment is the minute it arrives - not at the end of the month, from memory.
What this looks like in practice
The landlord portal records rent, deposits and water per room, keeps a running balance for each tenant, and gives the tenant their own view of it. Nothing clever: just the same four numbers, written down where both sides can see them.
Start with your current tenants, not with a plan to reorganise everything. Import the balances you know today, and keep going from there.
