The best resources for this question are going to be in regions where the ADU has been embraced as an innovative way to create more places for people to live: the Pacific Northwest, specifically Portland, are the key players here.California is not too far behind because the state has made it much easier to permit an ADU through laws, including the latest in early 2020.The basic answer to the question is a permitted ADU should add 20-30% to the value of your property.

Your on the right track technology is time traveling.

Find a real estate brokerage that offers daily/weekly trainings, great technology, and a supportive environment!

I put in technology like online rental, security cameras, etc.

Regulations are a bit gray and ever-changing around texting right now because it's still new (and those overseas fly-by-night orgs haven't missued the technology yet), however most companies now agree that peer-to-peer does not require consent since the platform is "manual" and not an ATDS.

But, I'm pretty sure that it will bring up the rental prices and will adjust the housing prices compare to other houses state wide as most of those fulfillment center employees are going to be between 12 to 20 dollars per hour, excluding managers and eventually will want to live closer to the job.Comparing the housing market in and around the NJ,  homes in Burlington are way below the NJ property average and some cases I would say way below the national average home prices with that much of development of what the future is going to be.I'm just happy to see the more jobs coming to the towns and it will not only attract jobs but more innovators and businessmen closer to these fulfillment centers with independent ideas, while businesses focus on building and let the fulfillment center take care of somewhat of customer experience and shipment over the internet. 

We've been harrassed by this person for months, so I followed the city police advice & had the tenant removed in Nov 2021 using a Temporary Protective Order.

There is strong job growth as companies cluster to "innovation islands," an increase in population follows, and they are geographically constrained making development harder and much more expensive (unlike DFW, for example).

They will still exist, but in a much lower quantity where they have to surcharge their transactions perhaps, and technology platforms will take over (like Travelocity, and Expedia did in the travel space).  

@Thomas Burnett I am still perplexed in this day and age of technology and internet people are still driving for dollars.
