If someone is bringing a deal and you're determing if the numbers might make sense, I use a Dollar/SQFT estimate based on amount of rehab needed

Would love to jump on a call to tell you the reasons why investing in Memphis makes sense.

With a utility provided by the government, it makes sense to keep the bill in your name because usually if it doesn't get paid it eventually becomes a lien on the house. 

I think you will have the best time connecting with people in person.In the meantime you can start by looking at all the properties that are on the market in your area to get a sense of what's available and what prices they are closing at vs what they are listed at. 

If you want rental property, you could take that equity and buy several houses better suited to renting.Selling now makes sense because you can also avoid the capital gains tax because you lived in the property 2 of the last 5 years. 

It takes 5-15 minutes on any state site to set up on your own, without an operating agreement and articles which you will only need later.If you are setting up a single-member (just you), you don't need help and setting it up now for rental properties only makes sense if you have cash.

I've now focused on other markets where the numbers make a lot more sense from a cash flow perspective.

This makes sense and sounds like a good approach.  

I’ve been hearing a lot about cost segregation studies and have a few questions…- What are some of the key factors that determine whether a cost segregation study makes sense?

Great rule of thumb too...doesn't make sense otherwise at all.
