Looking for some help with this specific investment – apartment block what move to make

Hello all the wise owls, hoping for some thoughts of wisdom and advise. I am not sure what move to make

I am looking at an investment property in a low rise apartment block ( 3 storyes) but quite large across so about 120 apartments.
Its a 1 bedroom the suburb is glenhuntly which is 10KM from CBD.
Strategy is long term hold of about 7 years
I think I can purchase between 310000 and 330000

My Pros
– Only 3 years old so can still depreciate
– Rent is quite good for a 1B at about 340/350 a week
– Monash Uni a walking distance away may always bee in demand from students
– Train line right behind the apartment (this apartment faces the other side- so min train noise but 2 min walk to tram and train)
– Godd shopping strip nearby with Carnegie and Glenhuntly

Cons
– Big apartment block
– 1 Bedroom
– Body corp about 2000 a year
– Unsure of Capital growth factor – can anyone suggest how I can find data to see this. Glen huntly is a good suburb so property growth is really fair BUT  am sure an apartment of this size would grow at a different rate
– Original builder went under and  the body corp sued and won. Some of building is being completed… mainly cosmetic (How can I find the original prices for this apartment)
– Cant tell if there is a problem as there are a number of units up for sale for being 120 unit block I am sure that will always be the case?

Can anyone give me some pointers, thoughts? What do you think of my Pros and Cons. I gues my main concern is really samll capital growth over the 7 to 10 year period.

Really appreciate any advise or comments
