In numerology, a lucky residence is one that resonates well with you.

I can talk about the unit number, but not the street number. To calculate the street number, both the number and the street name are required. Your question doesn't provide the street name.

See the Street Address Numerology Reading numerology tool to obtain a reading on the street number.

The unit number 7 is good. It resonates well with your current life cycle number 11. Your life cycle number changes in year 2013, when it will become the number 1. A unit number 7 can also resonate well with a life cycle number 1.

Your heart's desire number 3 and your life path number 3 also resonate well with the unit number 7.

There is some conflict between your name number 2 and the unit number 7. The number 2 resonates with companionship and the number 7 resonates with introspection. Not much conflict. But be aware there may be some.

The unit number and street address have little influence on your whole life. There is some influence while you are present within the building.

Do see the above linked numerology tool for a reading on the calculated street number. It can provide more information than the reading for the unit number 7 I was able to do.
