What entries should I make for these whole transaction?

To correctly record these transactions, you would need to make the following journal entries:

1. Initial Purchase of the Property:
Debit: Property (asset) - $100,000
Credit: Cash (asset) - $100,000

2. Depreciation of the Property:
Debit: Depreciation Expense (expense) - $30,000
Credit: Accumulated Depreciation (contra-asset) - $30,000

3. Additional Payment to Mr. Za:
Debit: Property (asset) - $200,000
Credit: Cash (asset) - $200,000

4. Loan Taken from the Bank:
Debit: Cash (asset) - $200,000
Credit: Loan Payable (liability) - $200,000

Please note that these journal entries are based on the assumption that the property is a long-term asset subject to depreciation, and the depreciation expense is recognized annually over the asset's useful life. Additionally, it is assumed that the loan taken from the bank is a long-term liability. As accounting practices might vary, it is recommended to consult with a professional accountant or refer to your organization's accounting policies to ensure accurate recording of transactions.
