kokoyong-It is difficult for homeowners to have meetings in their homes, I had one in my home for awhile and the wear on your house can be difficult to watch. Plus, you have to keep it super clean, which can be difficult to do when you are a working mother with a baby. No one offers to come over and help you clean like they do the Kingdom Hall. I'm not surprised that the congregation where you are is now renting a place, maybe the homeowners got tired of all the thankless work they were expected to do.
They will probably make the attendees feel guilty enough to contribute the shortfall in funds that is now occuring.
