Detached Houses to the value of $200 000

In order of your questions, my answers are:
Yes houses, maybe new for up to $200k or some less, still but hurry over
No apartments here, just houses, water, fishing, peace and quiet, no keeping up with the Jones's here, laid back, don't expect an "estate" feel here, lots of people are houseproud, some are not
Yes rent first
Lamb, $600.00 approx per quarter, including water, for a 600m2 block
Some druggies, 4 cops now on Russell, just stay away from that sort
Yes tradies on all 4 islands. Small hardware stores on both Russell and Macleay. All builds must be approved by the Redland City Council, the days of throwing a shed or hut up are gone as a few bad apples built, left there shacks to rot and the council won't allow that anymore. A good thing I would think
Finally: Doctors, dentists, chemists, pathology on both Russell and Macleay. One pub (Macleay) bottle shop on Russell. Lots of clubs, or groups to join. Libraries, Art, churches, music/singing/dancing, garden clubs, bridge club, sport to watch or participate in, a couple of cafes and takeaways on the islands. Travel, on the passenger ferries, is free between all 4 islands. You can walk on the vehicular ferries for a minimal fee also. No public transport, but taxi's or Little Bus service on Russell, Macleay and one usually on Lamb but not at the moment. Lamb and Karragarra are walk able or mobility scooter friendly, as small islands
I would think you could get yourself a good group of friends, on the islands, as you have no family, if that is what you want
