What is so fundamentaly different between 1991 (the Dark Ages to Millennials) and now?

Millennials and baby boomer demographics are huge....in my area there is definitely trend of them moving to more urban areas and first ring suburbs.

They sound like overly entitled millennials that need to grow up.

@Walter Antonio For rentals I typically like areas that have:1) Strong income growth2) High millennial presence3) Existing base of rental demand.Below are the Vegas ZIPs that meet those criteria.You seem to be onto something with 89138. 

Over the last few years our downtown has undergone a huge transformation and we're a huge destination for millennial entrepreneurs, which is good both for culture and innovation now, and long-term tenants /potential owner-occupants down the line when they settle in to start families.

Millennials love to live there and homes are still relatively affordable for investors.

They're looking to relate to Millennials so 40 years old would be max and good on camera as well.

But housing demand is insane now and will only get worse if millennials finally start to buy.

When I bought it, it was with the intention of my dad living with us until he needed to go to a home; but I also had recognized that there were a lot of boomers, as well as millennials, whose families would benefit from that sort of set up. 

Millennials also seem to not value home ownership as much as past generations, they value the flexibility of being able to move and change jobs.
