Johor Bahru the highest price Bird House selling Rm4800000

Today pass by Johor Bahru town, meeting another swiftletfarming kaki. according to this friend, the highest price of BH selling in JB, was this tall building use to be a hotel. Rm4800000. I wonder how much nest inside?? I guest the owner must be very enjoying now. vacations, big house, expensive car, young chicks. haha!

Note that there a light put on the entrance hole at the second photo, some people dont know why some other people put a light there and most of the people just follow, you might want to follow as well. But where exactly the appropriate place and how bright and whats the time for switch on. some say the light work for guiding the bird to know the way of home, haha! Do you think so? there s too much light on the street that might confuse the bird if the light work this way. But if the light are not function as guide, what does it sitting there for? You might want to find out why??
