This guys are very smart, they have studied the market and realized the middle class are paying good rent...but not buying the houses. If they don't grasp this people and tie their hands for 18 years+ their houses will not have buyers.
Instead of missing out on house buyers and ending up with tenants or empty houses, they have sweetened the deal by choosing the tenancy purchase as a PLAN B so as to survive this market. Good strategy. Apa wengi watanaswa.
