Great neighborhood, that’s where I live but not ideal for REI..Most apts are Coops the majority of boards won’t allow you to rent and if they do there will be restrictions..SFHs, Multis or Condos prices are very high, it will be difficult for positive cash flow every month..

They are extremely difficult to achieve positive cash flow long term.

As you scale your business it will become increasingly more difficult to allocate your expenses to the proper rental or business if expenses are running through your personal account.
