Be aware though that things can change. E.g. when we visited our school we were told that music was very important to them, there was a dedicated music teacher, all children would get to learn instrument A in year 2 (I think) and instrument B in year 4... That is one of the things we liked about the school.
But the fantastic music teacher didn't get on with the new head, and left. Ever since, music has been only an afterthought, if at all. The 'music: fantastic' tick turned out to be a 'music: really poor' reality.
Also, the 'promised' one-full-time-TA-per-class-and-two-in-reception has long since disappeared in favour of financing more office staff and creating new leadership positions.
And the experienced, long term, a bit older staff have all left; not long ago, the teacher who was starting her third year at the school was the most senior teacher around. The school is financially sound because all teachers are on starting salaries.
In hindsight I would suggest that wherever there is a new or fairly new headteacher, the only thing that is any indication of how things will be is a chat with the headteacher him/herself. And listening very carefully to what they are saying/are not saying. Some heads are very good at the 'marketing talk' so you have to be very attentive to what they are actually saying, beyond the glossy words.
Also in hindsight, I would suggest giving added weight to the factors that are less likely to change. E.g. location, what the school run will be like (along a busy road or through a park?), facilities/infrastructure, size (how many children/year), that kind of stuff.
