I've 2 apartments, one hdb and one condo. Both apartments are serviced by my earnings.

I live with my wife in condo, while my mum stays in hdb.

My condo has been analysised by fengshui geomancer

Should i ask for geomancer fengshui analysis inmy hdb flat since i am not staying there ? The hdb place is for me to place my son with my mum during working hours and i pick my son after work.

Also note that 1 of the hdb room is being sublet for rental.

Frankly Feng Shui cannot be done by remote control. Thus, you are correct to do a Feng Shui of your condo since primarily this is your abode (home). While the other address is a "depository".

In addition, if it ain't broken, don't need to fix it, does apply.
