You can do this after you close on your property just keep in mind not all loan programs allow to close or Quit claim into an LLC. 

I would set appointments with local investor/agents who are tapping the market you want to serve (just look at closed multi-family listings and see who sold them), and keep doing that until you find a person who stands to mutually benefit from coaching/mentoring you and expect to pay them a split to work alongside them until you're prepared enough to go on your own. 

They're big, hulking beasts that ruin a room's flow.I'd much prefer some shelves in a closet that closes.

I just need the pre approval letter to start putting in offers, or can I wait until after I close?

The cash flow from that property is close to nothing and if there are any issues with the property and you dont have the financial backing to handle it then it is going to be hard to deal with. 

I do work at a home building supply store, so getting a close estimate on materials will be easier for me when running that side of things.

I have used Gary Mcannally for 300 closings. 

Finding properties off market and getting seller financing reduces closing costs by a heck of a lot, and often you can find sellers will not be over the top on pricing, as their properties need some work when they aren’t actively looking to sell.  

My dorm happened to be an older building but, due to the close proximity to two colleges and a station I’m pretty sure it was successful .

Then the company says you get it back when you close your first deal with them..
