Do I buy more or buy in higher appreciation markets

[Al Caan]

Hi Bigger Pockets:

So I have 5 units in a cash flowing market, section 8 and yes I have tenants that don’t pay etc, my question are:

1) the area does not appreciate like San Diego, so shall I buy more of these ~$60k ~$400 net cash flow, or shall I buy in better appreciation markets?

2) With the properties not appreciating much, can I BRRRR and pull my initial investment back out so I can grow?

Thanks
