What are the best ready projects for immediate rental income?

A smart investor does not ask only whether the project is completed.
The better question is whether the building operates well, whether the unit type is in demand, and whether the running costs make sense against expected rent. Some ready projects look attractive but suffer from weak management, heavy internal competition, or inefficient units.
Focus on an active area, a stable building, and a unit that can be marketed easily.
When rent readiness is clear, value is clearer too.
