Hi Matt,
Welcome to BP and the real estate investing world.
I am also in the Lansing area, just south of you in Holt. I closed my first deal about a month ago. We bought a duplex, renovating it, and then living on one half while renting out the other side. Hoping this move will help us save more money to put towards our next deal.
I am still fairly new to this, but let me take a swing at your questions.
1. It depends a lot on what exactly your first deal is going to look like. Are you hoping to use other people's money to finance your first deal (i.e. private money, hard money, etc)? I haven't taken that route yet so I can't speak to the order of progression.
My first deal is owner occupied to is allowed me to put much less down up front. I got in the door for under 3K, which means i just used my own cash. If you are buying a pure investment property/flip (i.e. you aren't going to live in it) you will need to put down much more up front (25% usually). You need to determine if you have enough cash to make that happen on your own.
2. Having a house under contract means you put an offer in, it was accepted by the seller. Typically there is between that point and closing (when you actually own the property) there are several weeks or months for due diligence and for financing to get lined up. You due diligence is usually related to any contingencies you put in your offer (inspection or otherwise). If you are financing then your lender will typically need some time to review the deal, your suitability as a borrower before lending the money.
3. I worked with a great agent for my first deal that I would happily recommend to others. I plan to work with her again on my next deal. PM and I can give you her name.
4. Once I just into this game I was surprised about how many people in my circles were involved in REI in some way or another. Until I bough my first property and started asking questions, I had no idea! Be open about what you want to do with your friends and family and see who pops up. Turns out my grandpa, uncles' girlfriend, an old family friend, good friend's parents, my in-laws next door neighbor, and another good friend of my mom are all in real estate in one way or another. I just started having conversations with them and have been learning a lot. None of them are particularly mentors, but they are helpful connections.
PM if you want to connect sometime.
