@Thomas Bailey I can't speak to the financing aspects as I'm still new to this myself, plus i am concentrating on the commercial side of real estate.
If you want to check rental rates, check Craigslist and KSL for similar properties in the area and see what they're renting for to give you a baseline. You can also use Trualia's Heat Map (Google it) to give you an idea of what the average rate is per bedroom.
Remember, just because you CAN get more, doesn't mean you should. ESPECIALLY if you're going into the SFH arena. Unlike MFH, where your risk is spread over more units, if you lose a tenant in a duplex or single home, YOU eat that mortgage until it's filled again.
In order to know how much income a property may produce, use the BP Rental Property Calculator tool. It will give you a great place to start. If your a non-Pro member, you'll only have access to five reports. But even if you just plug one of the ones you listed above, you'll have an idea of what to look for.
As I'm still learning, I THINK I have this right when I say, there's an inverse relationship of Cap Rate to Price (or NOI). Basically, the lower the cap rate, the higher price the property, and greater appreciation. The higher the cap rate, the higher the cash flow, but less appreciation. SLC in particular has low cap rates right now. With such low unemployment and hot RE market, the prices are high (in my mind), and rising. And with that being said, don't be afraid to look outside the state. AZ, MI, FL, TX, TN.. TON'S of places with cheaper prices and decent cap rates.
I can't stress how important it is to start consuming as much reading/podcasts/youtube vids/etc as you can, especially in whatever niche you're going to focus on.
