Well, let me explain why and how BH ranching to most can make money in a long run provided obviously you can get nests.
1st. year is critical years on whether if you are on the journey to richness or not.
2nd. year is forget your GR scheme or you are on your way and if so, you will find a steady increment of nests.
3rd. year is a year when you shall know if you are there or still retain in 2nd.year class and if you pass the 3rd.year class, you maybe on your way to wealth.
After the 3rd. years and if you are successful, you are already in K nests status and in the coming year, anything can happen and your BH is now officially a self supporting BH where you can support your own increment of nests and will able to increase more than you may imagine provided obviously, you do no unnecessary modification as your BH is already a sanctuary for swiftlets without anymore renovation which may do worst than improve the situation. Also, since your BH is old, the older the better to get other BHs new fledged birds..
At 5th. years, you are already rich as you now have got back all your investment and your BH now value afew time your investment and that's what I refer to as your true return for being patient and kind to the swiftlets.
Assuming that your building cost RM150K to building and with the land will cost you about Rm250K and after 5 years, the inflation value of the BH will be at least 500K but you haven't taken in to account of the nests value which is at least RM500 per nests and having let say, 3K nests and that work up to be Rm1.5M. Totally, RM2M if that doesn't satisfied you, I don't know what will which you only invested Rm250K at the beginning and you have got the investment back in 3 years. So, the Rm2M is pure profit!!!
Do you agree?
Totally agree with your points .. But i believe it is ideal case and true maybe 10 years back
However , with the current situation. what the success rate to pass Year 3 to get into K nest status?
A lot of my friends are having less than 200 nests even after 3 years.. not to mention K nests.
