As Brady says there is a lot of development going on in the area, but also a lot of public housing and ex-housing trust. I don't know about that particular street, but another half dozen streets on from there toward WL Boulevard I have visited many times and it's not a pretty area, Elizabeth like in it's appearance and resident type.
It's a cheap area for a reason.
Any poor tenants in the area will be gone within 3-5years IMO. Looks around at how much development is happening. There might be some dodgy tenants or OO who have been living in these properties for along time. But these old big blocks are going for modern townhouses. These types of people can't afford to live in the new properties being built.
