Bullmastiff's are a truly beautiful breed, and were actually one of the three breeds that we were very seriously considering. Their wonderful around family, and children (provided there is supervision), and sometimes they get along wonderfully with other dogs and small pets: However...
There are some issues concerning same sex parings. Usually it's males who are unneutered that can have dog aggression, but other wise they're tolerant dogs, when properly socialized and trained**. They are a dominant breed, and with a stubborn attitude mixed in, you definitely need to have a firm (yet gentle) hand when training.
We had the pleasure of knowing a couple of BM, and both (males) had absolutely wonderful temperaments. The one especially had a penchant for children and would have given his life for them. He was tolerant of the neighbourhood children playing with him, as well as other dogs. The owners also were well protected. In the four + years that they so far had their BM, not once did they ever lock their front door. (
) The other was owned by a police officer who had small children and needed a dog noted for it's gentleness.
**This is where finding a reputable breeder comes into play. Some have never had any issues with aggression, others may have some who are more dominant, and need a more experienced handler. Plus too, seeing as BM are prone to several health conditions, an experienced and knowledgeable breeder will have screened for the usual health suspects.
You mentioned that you have already been doing some research
