@Antra M. For your first question, bad idea is relative to your situation. Do you have a lot of cash on hand to deal with repairs that come up (CapEx), or to cover costs when there are vacancies? If so, it could be more of an appreciation play. If not, it's going to be a big drain on your finances. Having cash flow softens those expenses, and if you're lucky it can be totally self sufficient after a while. And if you accumulate more properties and pool the cash flow, it really starts to snowball. While rents might go up, they also might not. Buying with hope is more speculation than investing, and it could bite you. It's worth studying data to make sure you're using real numbers and trends to make that decision. That said, Raleigh has been appreciating like crazy and doesn't show signs of slowing, so while rents might not be keeping pace, a breakeven property can still be a good investment if you have the funds to cover CapEx. A lot of properties have doubled in value in the last 5-6 years.
I personally would do it only after having a few properties that do cash flow, so I can rob Peter to pay Paul. I don't like dipping into my personal funds. If you do decide to take that risk, a good way to keep costs low initially is to consider new(er) construction. You'll have a much lower chance of any crazy expensive roof/HVAC issues for a while (knock wood), and that will give the rental market time to catch up. You may also want to only buy in nicer neighborhoods, so you are attracting tenants that are more likely to take good care of your place, keeping turnover costs lower.
Lastly, just listen to a ton of podcasts and read as many books as you can. A lot of this will just seep into your pores after a while. :)
