Hey Steven and welcome. I'm from Beloit WI which isn't all that far from you. Just over an hour abouts. I would have to agree strongly with Dawn on getting yourself into a D class area. Personally I have 1 house in what I would consider a close to D class area. It was my first and has been a lot of problems in comparison to my others that aren't in that area. I'd stick with B to C starting. Otherwise your more likely to be dealing with rent excuses, more destruction to the property and just over all more time and effort as others are stating. As far as money goes if you have good equity in your house it's a great tool. I'd be careful starting out with a hard money loan and trying to refi later. It's a little riskier if your unable to refi as stated above or other unforeseen issues. If you can utilize a bank loan off the bat. They are pretty easy for the first 4 loans depending on your debt to income and credit. Also a lot safer and lower interest. That being said sometimes you do what you have to in order to succeed.
One great way to get started would be to buy a duplex and rent one side while living in the other side. That's a method many use. I haven't personally but it seems popular and makes sense. Many different techniques which makes investing so great. I will say listen to the BP podcasts and look at the resources like the tenant screening guide. Also that meet-up is a great idea. Learn and connect but don't sit around doing only that. At some point you need to just jump in.
Hope this helps a little.
