Buying out of State

Looking to purchase long term buy and hold rentals.

After looking for months and looking at various “wholesale deals” I have found very few deals that have positive cash flow, yet need only light cosmetic work.

I am located in Baltimore, and I have begun to look toward York, Pa which is 45mins away. Deals are cheaper, have good cash flow more often, and meet my general criteria.

My main question is if I buy out of state property, what if any are the extra tax or different taxes and liabilities I will take on
Will my MD based LLC be able to purchase in PA, or could it be more beneficial to start an LLC in PA?

Any help in this area would be greatly appreciated.
