How do you set this up with the city and the client? 

Columbus has been booming lately, thanks to big tech companies like Intel ($20 billion), Meta, Amazon, and Google setting up shop here.

We love ADUs and have evolved our business model to target properties that have a severely distressed main house and a secondary unit that can be converted to an ADU such as a detached garage, shop or studio.

You're looking for a plausible answer based on analytics, not opinion or “feelings.”Tell me about the tenant pool you target. - Understanding the existence of tenant pools and their characteristics is not common knowledge.

Personal recommendation is @Scott Trench 's set for life book on personal finance and Brandon Turner's The Book on Real Estate Investing.
