For long-term growth, consider newer single-family homes in high-appreciation suburbs or well-located small multi-family properties.

Location, location, location.  

There are more factors than just the community (#beds, level of theming, location to the amenities, style of home (single family, townhome, condo) and others) But I would strongly advise to stay within some of the same communities you mentioned like Storey Lake, Windsor Hills, Championsgate and a few others if cash flow is your goal.

Yeah, but it's not a magic way to save on interest."

I didn’t see your location in your profile or your post, but assume at least 17% state/federal taxes leaves you with $10k/yr. 

Idk if I like this tertiary of a location way outside of DFW.

Depending on the location and the city, these could take a long time.

While they offer great general advice, they can't speak to our market, or the potential of a property located in Scottsdale can provide if held. 

@Ofir R.Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

The main thing is to stick with great location and premium properties.
