Secure Investment 12-15m / 3-4 years

I am considering following options for investment:

  1. Dha phase v home 5m (for rent)

  2. Dha phase 1-4 10m old home (for rent)

  3. Dha phase 9 town files 5m (3 files)

  4. Dha phase 9 prism files 5m (4 files)

  5. Dha phase 9 prism files 1k (2 files)

Please suggest whats best?

2-3 years is very short time for no. 3,4 & 5 … So think twice for short term investment.
