The landlord's logic
When everyone is increasing the rental or the sale price of the properties, I must also increase lah. But your propertiesre built 30 years ago and your cost of maintenance did not go up so much, why are you doubling or tripling your rental and price? It is business lah. Business means make profit, as much as the other party can pay. And don't forget, my own pay and bonuses must go up to keep up with my higher standard of living.
