What a rental unit really costs to maintain per year (Serdang landlord guide)

The number first: for a typical rental around Serdang, Seri Kembangan or Balakong — an apartment or older terrace renting at RM 1,200–1,800 a month — budget roughly one month’s rent per year for maintenance in a quiet year, and closer to two months’ rent in a year when a tenant moves out. If your spreadsheet assumes zero, it is not a budget; it is a hope.

What actually breaks in a normal year

After enough call-outs to rental units in this area, the pattern is boringly consistent. It is almost never the big dramatic failure — it is wear items:

• Taps, bidet sprays and toilet cistern internals. Cheap fittings installed at the last renovation wear out in rotation. Each is small money, but they arrive every year.
• Clogged drains and floor traps — the most common tenant complaint we see, especially in units rented to groups of sharers.
• Water heater problems. Elements and ELCBs in daily-use units fail far sooner than in owner-occupied homes with one shower a day.
• Small electrical faults — a dead socket, a tripping circuit, a fan regulator. All wiring work on our jobs is carried out with our licensed partner contractor, Suruhanjaya Tenaga compliant.

One thing experience teaches you to price in: tenants under-report. A tenant lives with a dripping trap under the kitchen sink for a year because it is not their cabinet rotting. You find out at move-out, when the RM 150 drip has become a RM 600 cabinet-base replacement. This is why a yearly inspection visit pays for itself.

A realistic annual budget

That lands most owners at RM 800–2,000 in a normal year for one unit — before turnover costs.

Turnover years are the expensive ones

When a tenant leaves, the deposit rarely covers what the unit actually needs to show well again: repainting (RM 1,000–2,500 for a typical unit), deep cleaning, curtain rails, regrouting or fresh silicone in the bathrooms, and the small repairs list that accumulated silently. A fast, planned turnover also protects the bigger number nobody writes down: every vacant month on a RM 1,500 unit costs you RM 1,500. Spending RM 2,000 to re-let in two weeks beats saving it and sitting empty for two months.

The big items ticking in the background

Separate from the yearly churn, some costs arrive once a decade and hurt if you have not saved for them: bathroom waterproofing fails with age and heavy use (re-waterproofing runs RM 1,500–5,000), and a tired bathroom eventually needs a refresh (RM 3,000–8,000) to keep the unit rentable at market rate. Putting aside RM 100–150 a month into a sinking fund means these arrive as a plan, not a crisis — and in older Serdang-belt blocks, a leaking bathroom that stains the ceiling of the unit downstairs becomes a neighbour dispute on top of a repair bill.

Keep every receipt

Repair and maintenance costs on a tenanted unit are generally deductible against your rental income under LHDN rules, while upgrades and renovations are treated as capital and are not. The practical habit: keep itemised invoices for every job, labelled by unit, and let your tax agent sort the classification. An itemised invoice — which you should be demanding from any contractor anyway — does double duty here.

Or make it one plan instead of ten phone calls

If you own one or more units in the area and would rather not manage this trade by trade, that is exactly what our landlord package is for — inspection, turnover works and on-call repairs handled as one arrangement, with honest published price ranges. Either way, budget the one month’s rent. The owners who get caught out are never the ones who planned for repairs; they are the ones who assumed there would not be any.
