Any other tips, recommendations, etc are most welcome.

I have never purchased through one so I am looking for any ideas, suggestions, tips, etc.

I work in comp so I have no issues building my own but I'd prefer to simply use one that's already created.Finally, aside from reviewing prior projects on the company's website and scouring the internet for reviews, does anyone have any tips on how to select a given company?

Thanks for the tip on Fountain Hill.

You will constantly hear of  shortcuts during construction and the conscientious decision to use lower quality materials during the renovation. 

Your returns in investing ultimately come from exchanging terminally abundant goods (fiat dollars, debt/future fiat dollars) for terminally scarce goods (high quality, supply constrained real estate).Selling to go into cash isn’t of interest unless I have a short term need for that cash or am funding another purchase.

For example, if a 1,600 sq ft main house is appraised at $100 sq/ft, what could I expect a 600 sq ft ADU of similar build quality to be appraised for?  

Any tips from you savvy folks?
