It would be ideal to chat with investors operating in the Midwest, but I welcome anyone's perspective on BRRRing from a considerable distance (plane flight away).Thanks!

You can't go wrong with holding the property but again not ideal in your scenario

Should be within the last 6 months sold ideally within 1 mile. 

However, I would encourage you to Network work local real estate clubs in the PA/NJ area to help identify your target market and ideal investment for your first property.

Do you have an ideal type of and location within TX/Dallas for a flip?

Investing locally would be ideal for sure.  

And working for a contractor that does flips or rentals would be ideal.

Your name and credit would stay with the existing note, which you would keep paying on - ideally yourself with money you receive from the "buyer", because if they don't pay your credit is wrecked and your house is in foreclosure.If you search on here you'll see everyone and their brother looking to do Subto and it's a nightmare unless the buyer has the funds to pay the note off if/when the original lender figures out you don't occupy the property any more and are attempting to do what you want to do, since most loans are going to specify that performance.  

I highly encourage everyone to view the property before putting money down, but that's not ideal for many of them, so I do allow them to rent "sight unseen," but I am very open with them to ensure they don't show up and back out.1.

@Jaren Taylor, not sure if this is why you talk about raising all cash, but given most deals are trading in the 5% cap rate range, and agency debt is 6.5% while balance sheet debt is closer to 7%, I whole heartedly agree that all cash is the ideal capital structure for many properties today, if your goal is to maximize overall returns for your investors.
