Kids sharing rooms...opinions?

We currently have a 5 bedroom house and we are trying to get pregnant with baby #4. This will be our last baby.

Our dilemma. We love our house, but the town we live in is not the best/safest. We are debating at this point in time if we would be better off living on base (husband is military). We hate to get rid our our house, but safety is a bigger priority.

My kids would have to share bedrooms if we lived on base...especially if we have another baby. I don’t know if it’s fair. We are already in process of having another baby—using fertility treatments.

Our kids are 9 years old, and 5 year old twins (boy/girl).

What are your thoughts? I’d love some advice.
