I think Brett has a Facebook group, let's keep in touch there.

But I think I would need to see more data to make an informed decision.

I think a great strategy would be to find someone who would like to house hack with you, and maybe even someone with a bit of experience local to the area that you trust and know very well to go in on the deal with you.  

These neighborhoods seem to fit my goals, especially with their lower crime rates and potential for growth.Do you think these are solid options, or would you recommend other neighborhoods in the Philadelphia area based on the price range and focus on appreciation?

I think you will have a hard time selling it with the tenants there, meaning you will take significant cut in your sale price. 

Didn’t think so.

Having them pay your LLC does not protect you from anything if that is what you were thinking.

I think the idea of starting fresh financially, as soon as possible, would eliminate a lot of stress.

You can't do anything without their permission and should rebuild it a few inches towards your property so it is entirely on your property and you avoid this problem in the future.If it were me, I would talk with my neighbor, "Hey, what do you think of this fence?"

I think its working really well.
