Tuen Mun Commercial Renovation: Does Spending $200K Actually Add Value? 屯門商廈裝修：花20萬，租金升得返幾多？

Every owner asks the same question:
"If I renovate, will rent increase enough to justify the cost?"
The answer is never universal.
It depends on structure.
1. The Basic ROI Framework
Renovation cost → Rental uplift → Payback period
If a unit rents at $12/sq ft,
and post-renovation achieves $15/sq ft:
The uplift is $3/sq ft.
On a 500 sq ft unit:
Monthly uplift = $1,500
Annual uplift = $18,000
If renovation cost = $200,000:
Simple payback = 11+ years.
That is not attractive on paper.
2. But Payback Alone Is Misleading
Renovation also affects:
- Vacancy duration
- Tenant quality
- Lease term willingness
- Maintenance frequency
A renovated unit that leases 2 months faster
saves $24,000 in lost rent alone.
3. Tuen Mun Context
Tuen Mun rents are structurally lower than urban core.
This compresses absolute uplift —
even if percentage gain is similar.
$3/sq ft uplift in Central = large absolute gain.
$3/sq ft uplift in Tuen Mun = same percentage, smaller total.
Renovation budget must be proportional to district rental ceiling.
4. Over-Renovation Risk
Spending $400K on a unit with $15/sq ft ceiling
creates negative return.
The market does not reward finishes beyond its expectation band.
5. Under-Renovation Risk
Spending $50K on cosmetic refresh
may not shift tenant perception at all.
The unit remains "old" in tenant's eyes.
Conclusion
Renovation ROI in Tuen Mun is real —
but bounded by district rental ceiling.
The model is:
Spend enough to shift category.
Not so much that you exceed market tolerance.
