The market is on an excellent growth trend as well.

Hello,I am a real estate investor interested in investing in Memphis, Tennessee, and seeking advice and guidance on the best ways to invest in this market.I have done some research, and I know that Memphis has a growing population and a solid rental market, making it an excellent place to invest in real estate.

Thanks Eric, I used to live in Tucson but this is excellent insight for strs in the area. 

How many hours it takes is going to depend entirely on the details of the project and how well all of the players involved (including you and your client) work together.If you're really trying to do this at scale and build "unlimited" houses, ditch the bring-your-own-materials plan and start building excellent relationships with contractors, subcontractors, and govt. building departments in the areas you want to build.

Excellent deal for the minority partners (zero cash contribution) but a low ROI even accounting for tax savings of $24k/yr on a $500k cash investment.

With a $400k budget, your choice of Phoenix is excellent as it's a thriving market.

I believe they´ve chosen an excellent land for this project. 

Credit history is excellent.  

Indianapolis is an excellent market to invest in.

Check in with @Joseph Chiofalo they work multi family nationwide and would be an excellent initial feasibility resource.
