As for an accountant do not feel like you need to use someone local. Many of us accountants have clients worldwide. Payroll, bookkeeping, etc can mostly be done remotely.
Also check out the www.NAEA.org page in your search. It should help you find someone local. If someone comes to me, I'll send them your way.
If you need help in your search or want to verify something don't hesitate to ask.
For example: I have clients worldwide and things are just as easy as I e-mail them, talking on the phone. I even use Skype and TeamViewer to communicate with clients so I'd highly recommend looking for one of the best with great references that interviews well with you.
So look for someone you can connect with that works out for your situation.
there are no real estate focused accountants in Pennsylvania. There are boatloads of CPA's that are knowledgable in taxes, both business and real estate, and financial matters. They are smart folks, most will be able to help you.
