Thank you for your insights, PK and kay henry.
1. I was told about the airport by the seller. But she could not give exact time on when the airport will be completed.
2. The house is 25 years old. Just being repainted about a year ago. Neat condition.
3. I have not find out more about the mining. From what I know, it was not the sole employment. The area is also a cattle raising area which a fair few number of people too.
4. There is public transport to nearest town (Bowen) twice a week. And to go area like Airlie Beach, Mackay there will regular buses from Bowen.
5. The property is owner occupied at the moment. Selling due to bad health.
6. There is only one tiny real estate agent in the town. I have spoken to them, given a range of rental of $100 – $160 per week depending on the ‘quality’ of home. I still reaching for other agent closer to the town to find out more about the possible rental income.

This will be the very first investment, so kinda having cold feet about the whole thing and looking for the best way to kick off.
But I would certainly look more into the questions you two have asked as the right questions do lead to the right answer. Well, I am working on ‘the answer’ now [happy3]

thanks again
