Congratulations! You're in the exact same spot I was in 2005, knowing nothing about real estate investing. I was a homeowner at the time (still am), but that's about all I knew.
First, ensure that you're both on the same page as far as your goals, how much time you're willing to put into this, and who will take what roles. You can do some trial and error learning as you go, but don't assume things like "He'll deal with the tenants"...."She'll clean the units at turn over." Talk over duties and responsibilities.
Next, decide how you are going to finance your transitions. Debt (i.e. bank loans/mortgages) is one of the most common sources of money, but certainly not the only source. Unfortunately, it is also the most common source of bankruptcy. Folks on here are very enthusiastic, sometimes to the point of forgetting to apply the "doubled edged sword" quality of leverage. It cuts both ways, magnifying both gains and losses, and when you don't know what you're doing early on it's easy to use debt to cover up bad decisions (overpaying for property, materials, labor, living expenses, etc). Private money / equity partners are another great resource. Don't discount those. Basically, you partner with investors who bring the money and you bring some of your money and the deals to the table. Share wisdom, profits and losses.
Third, I would try to decide what broad category of investing I want to try, then decide what strategies to implement to try them. Do you intend to be a buy and hold investor (rentals) or a churn and burn investor (flips, wholesaling)? While it is possible to do both, it's harder to both well with limited experience. I recommend trying one approach and see if you like it and are any good at it. Within each category there are tons of different strategies to follow, such as driving for dollars, direct mail marketing, bandit signs, foreclosures, short sales, the dogs of the MLS, residential, commercial, special use, tax lien sales, notes/paper, hard money lending, syndication, estate sales, REITS, etc.
Fourth, connect with a local real estate investment association (REIA). BP is sort of like that, but you'll never get the same level of insight into your local market as you will talking with folks who do this stuff day in and day out. Be advised not everyone at these meetings know what they are talking about, so always get 3-4 views on any given strategy. Watch out for shysters who prey on newbies with too much enthusiasm and not enough wisdom....don't just give anyone money or control of your assets.
Fifth, lots of reading. For solid advice with practical steps, I recommend John Schaub's Building Wealth One House at a Time if you're into residential rentals. That's been my main area of expertise over the past 16 years. Now I'm getting into commercial, but not experienced enough yet to recommend any good books.
That ought to be enough to keep you busy for the next 3-4 weeks or so. Good luck!
