possibly simply overpriced.
Investors are looking for cash for and ROI.
Properties in PB do not certainly provide positive cash flow at that price
Also, Grand Avenue is a busy street. Not really the best in PB even though it is close to the ocean.
It looks like they are all part of the same complex.
The seller may have to sell them all at once.
If you are very interested or would like me to call the listing agent to find out more information about it I'd be happy to do so.
Hope this helps
