@Jason W. I got my Licences a few months ago and will just tell you what I would have done knowing what I know now.
1. keep your day job so you can qualify for loans if not your will need a partner with lots of cash I did I was lucky . Yes be a part time realtor/investor.
2. Find a multifamily property to purchase the larger the better because more renters means more cash covering your mortgage. If its your first property you can obtain a 203k loan( this will finance the purchase and construction loan)
3. Find a multifamily that needs renovations so you get it at a discount and can rehab below the actual ARV and later refinance
4. Oh yeah join a team or a realtor that already invest in rentals so you have a built in mentor. They will help you write your first contracts but you will split your commission. But getting paid to purchase your rental is a nice situation ( I did this on my first rental and looking for a multifamily currently)
5. If you can rehab your multifamily below the ARV you can refinance out of the loan and possibly get some cash. Also asap ( 6 moths typically) the refi will allow you to do this process in a year again because you cannot have more then one 203k loan or FHA first time buyer loan out at once. But you actually don't have to be a first time buyer you just can't have two of these loans at one time.
6. Read Bigger Pockets " The book on managing Rental Properties" so you can manage your multifamily and save 10% instead of hiring a property manager. Its tough but worth it.
This is just what I have learned and I probably am missing a few things but this is what I can think of at the moment off the top of my head.
