I am a new investor and after picking the Charlotte market and learning about the due diligence fee, I was wondering what other nuances there are for other markets that are specific to that market and not real estate in general? 

Hey BiggerPockets Fam, I picked a tough time to get into real estate. 

Duane  very few houses these days have open houses the seller can instruct the agent NO OPEN houses. so thats how they handle that.and of course you want to pick a realtor who is investor centric like I do. 

Pick a neighborhood/town/city to lock in on (farming) and absorb as much knowledge as you can.

I plan to give them a call once I can track down the phone numbers.My question is, what things should I be doing to prep before I pick up the phone?

You've picked a good spot to fast track your goals. 

They picked the $$$ off.     

Prices drop and those of us with liquidity pick up the pieces at pennies on the dollar.If you have cash flow, you have staying power, and can make it through the bad times. 

Pick up some books at your college library and jump on in, the water is warm!

Pick up @Brandon Turner's book (https://store.biggerpockets.co...) for a how to guide.I will say one thing though, it's hard to get deals for no money down, even BRRRR deals.
