i'm not a master but here are a sequence of feng shui checklist that i follow when looking for in a property that i am buying to stay...
1. best facing direction - based on your birth year, you will be able to find your 4 best directions. I will look for a unit that is facing one of my best direction. if you have a spouse, pray that her she belongs to the same group as you are
2. after finding a unit that is facing my best direction, i will map the natal chart of the property (as mentioned by Kevin), to make sure that at least, the main door is in the good sector of a period 8 chart(feb 2004-feb 2024). in my opinion if there is a bad sector in your house, you can minimize the usage...but if your door is in a bad sector, it can be quite difficult to manage.
3. stand at the main door looking out and vice versa to look for any blockage or poison arrows that may disrupt the chi flow.
4. trust your first feeling when you first step into the house.

honestly, to me, finding a property that conforms to good feng shui and expecting it to be in a location that you desire, with price that meets your budget etc is kinda difficult....so i try not to put too much emphasis in feng shui...but the least i can do is to at least get the basic things right....

hope this helps...

from what i know, the natal chart is for 20 years...it is like the ba zi of the property....based on the date that it was completed? (i think).....the annual flying star chart is yearly....the stars move to different sectors of your house every year...correct me if im wrong....
