  1. Excellent posting as usual Pak Tommy!!! This is not something that most owners face but for us contractors we are ALWAYS agonizing over the question whether to rent (short term), lease (longer term) or purchase (long term)

    Keep on posting these really great topics……

    I look forward to seeing them each week…
