I don't think this will be overnight, and I think it was probably going to happen anyway as millennials take leadership roles in organizations, but the COVID-19 related restrictions may have accelerated that a bit. 

Microsoft and Amazon are moving in, the city just installed 5G (first city of its size to do so), 48% of the housing stock is affordable to millennials.

As a “millennial “ I’ve got savings to ride this out for 12 months as do most of my friends.

Also, the data online was very unreliable, and there were still a bunch of houses that were for sale that weren't listed online.I don't know what the data is, but on the ground millennials are pushing back against the traditional agent in my opinion.  

I know, can't rely on pslf/bootstrap yourself millennial/etc), and having more cash now to invest more aggressively.You are correct that technically rehab costs could likely also count for those purposes, but currently, rehab funds are limited and would need to be available for downpayments/reserves, and I honestly don't have time with my schedule for either sweat equity or coordinating contractors.

Two great meetups for those niches would be:Millennial Investors Focus Group:  https://www.meetup.com/Millennial-Investors-Focus-Group/ (These guys also have a thriving Facebook group I would recommend checking out).Future Millionaire Real Estate Investor Club (Fulton Realty) - https://www.meetup.com/Future-Millionaire-Real-Estate-Investor-Club/(These guys provide free snacks and drinks.

There has to be an APP to handles this - (millennial thoughts haha)My first offerI found a SFH with ADU fully updated and permitted.

In a market with a larger millennial population, yes.

For instance, I bet you understand the impact of the Beltline, or the plans for Grove Park or Airport City, or what areas your millennial friends are buying houses in way better than an out of state investor would.

There are more millennials than boomers (87M vs. 72M).
