“David’s video training saved us at least $15,000 on our DADU! We knew exactly what questions to ask and what to look for in the contract. Now we’re earning $1,950/month in passive income, and our property value shot up by nearly $300K. The 20% discount was the icing on the cake!”
“The combination of the video training and consultation was invaluable. We learned how to spot inflated costs and unnecessary add-ons before they happened. David’s team designed a beautiful basement ADU for my mother-in-law with lots of light and smart storage solutions. The 3D design really helped us visualize everything!”
“After talking with several contractors, Sapphire was the only one who actually explained the ADU zoning laws and helped us maximize our space within regulations. David’s video exposed all the tricks other contractors were trying to use! Their permitting expertise alone saved us months of headaches. Now we’re earning $1,750/month from our basement conversion that we didn’t even use before!”
