Welcome Andrew, As you'll soon find out from BP, there are many ways to dive into Real estate investing. Read all you can, don't hesitate to ask questions on this forum. People will tell of all of their successes, but also ask what their less successful ventures were and how they were remedied.
I believe in the turnkey model and what it has to offer and the ability to diversify into multiple markets. Multiple markets = multiple industries to fill those rentals. To get into solid rental, no C- neighborhoods you can expect to spend 80-175k +/- (175-200k being a brand new turnkey in a Edmond OK). You can get more for your money in some markets for example Jackson MS. There are many great areas to chose from with lower priced homes and good 12-15% (peaks if 18% cash on cash returns and are able to cash flow on average $300-350 per/mo after "The Big 6" (mortgage, taxes, insurance, vacancy, maintenance, management) are fully paid. Markets like OKC, Kansas City and Philadelphia can offer these kind of returns. Fill free to reach out if you have any questions. Best of Luck.
