I think it does make a ton of sense to look around DFW than right inside DFW.And yes, I would try a few different tools to get a rent estimate, not just Zillow:https://www.rentometer.com/https://www.biggerpockets.com/insights/property-searches/newhttps://www.neighborhoodscout.com/Neighborhood Scout has pretty good info on what returns look like for specific markets.

@Emily Anderson, more information needed about what you want to be different. 1.

Listing agents may need to have different commission agreements with the seller for different potential scenarios. 

@Ferrode Joseph cashflow vs appreciation is really a function of the Property Class you target.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.So, when investing in areas they don’t really know, investors should research the different property Class submarkets.

I was checking my ADU permit and noticed there are 2 different sq ft mentioned with 2 different date i.e on in the original permit and one in the new address. 

If you want to do residential, that is a very different area than commercial for instance.

What's the difference between an LLC vs Land Trust for an out of state owner?

I personally don't like this transaction, but everyone has a different risk tolerance. if you can aggressively raise rents and the market appreciates you are fine.For your assumptions the red flags that I'm seeing:0% vacancy should be higher unless your a PM and are experienced, even still.0% for management fees, are you a property manager?

Does anyone recommend doing this a different way?

The financial sophistication and operational capabilities for a large multifamily are much different than flips or BRRRs.
