Hey Daniel, Congrats on your decision to switch to philly investment properties. Philadelphia is one of the fastest growing markets in the nation and you are sure to make a lot of profit! Bucks County and MontCo are also excellent areas for investment. As an investment realtor, I've done a lot of deals out in those areas and I'm looking to do more.
Because annual taxes are higher in the suburbs, I would recommend expanding your search to include parts of Philly. Neighborhoods in West, North, and South Philly are also booming in the rental/flip market right now.
If you need help finding deals and analyzing numbers out in these areas, message me and I can tell you as much as I know!
