Build to rent SFH with ADU?

[Andrew Sundseth]

My wife and are planning to buy land in the next month or two so that we can build a home in the next year or two. Our plan is to build a SFH with an attached ADU that will cash flow and ideally have a good amount of equity upon completing the build. I am currently looking at house plans and I'm having a hard time picking a design that will be cost-efficient to build, produce solid cash flow, and appraise well. I know all of these results are relative to my budget but I'd like to get input from others who have built to rent or have ideas/experience to help me pick a good plan.

Thank you in advance!
