Is it Okay to Sell Property That Matches My Numerology?

I'm aware of no numerological reason to keep from selling a property that matches a number of your numerology chart.

Numerology influence from your numerology chart are intrinsic influences, always with you.

Numerology influence from property numbers (addresses, flat numbers, etc) are external influences. As such, they have an influence on you only when you are in the area of the property.

Influence From External Numerology Energy explains that.

Influence from property numbers have no influence on your personal numerology chart. Thus, it won't affect the energy represented by your personal chart to sell a property that contains a number that also exists in your chart.

If you feel you must have a property that resonates with your chart for your peace of mind, then it may be prudent to arrange another before selling this one. But that would be your own reason, not something required by numerology.
