Buying a unit in a street full of units – bad decision?

Hi all

I am looking to buy my first property as a stepping stone to buying a family home in 5-6 years time.

I wanted to buy in Yarraville and Seddon however they are both now too expensive with minimal villa units (my preferred property type).

Kingsville is a 10min walk from both Yarraville/Seddon VIC and is much more affordable.

However…they have 2 streets that are just old villa unit blocks, flats and apartments – minimal family homes. Does this mean that it will be more unlikely that the units will increase in value because the supply in Kingsville is so high? What other things to I need to consider?

Any responses would be much appreciated!!
