@Kaleb JohnsonRecommend 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 reality is the land has value.I believe you are typically far better purchasing a different property with conventional financing than adding an ADU.  

Here are some questions that I would typically ask a CPA:Are you experienced in working with my industry?

What kind of returns are you typically seeing on these deals?
