What are the reasons why some choose house church over traditional church?
We house church. For several years we had a house church in a large metropolitan area. We received about two inquires a year.
At first we were looking for a house church to join. We met some Christians that looked promising, but they were in the process of disbanding so the host family could move to a rural area.
Of the other groups that were listed in the House church directory for our city, they had either disbanded or were not what we were looking for. One group declared that they were ex-charismatics that were not interested in any teaching but would sit around and describe their past bad church experiences. While I could understand what might be called a group of spiritual refugees, I thought that wouldn't be the right group for our family.
We decided that we couldn't find an existing church, we would start our own.
You often find those with some theological axe to grind who have been made unwelcome (understandably) at traditional churches drawn to find those who will listen to them.
We now live in an area of very low population and where the people are very comfortable in their existing churches.
Here is a link on finding the "right" church and why it is so difficult.
Christian Pioneer - What is the right church
We have come to the conclusion that "church" is almost irrelevant. It is more important to find an older wiser Christian who clearly shows the light and love of Jesus in their life and ask them to help you know Jesus like they do. Over time you may be able to help others grow to know Jesus. I am not sure this relational "mentoring" process can ever be anything but hindered in an organizational "church" setting.
I think we need to cultivate individual relations such that we have real fellowship and relational connection (even at a distance) rather than settling for church activity and programs as an anemic substitute.
