If you're looking for long term buy & hold, there's money to be made. - Renting in this area is solid, I've gotten what they call B class tenants and more or less they've been great.

I'm curious to know how often property managers actively suggest value-add activities for properties (ie, building an ADU, remodeling, buy-fix-hold opportunities etc etc). 

That's great to hear that you're graduating and you want to get into multifamily.I would start off in a commercial real estate firm, learn the systems, the sales/buying process, how to analyze deals etc...

A lot of these folks dont want to share their own distuation out in public, so it may be a bit less "social" imo. but creating content around you buy houses / seller reviews and explainng the process at the very minimum will add a huge credbiliity boost to your website and will warm you a lot of seller leads before you ever speak to them!

I am looking to buy another multi family property but have noticed lots of obstacles when looking off market.

And yes, you can buy existing stuff at a discount from new construction for sure. 

Either way, i always decide to buy additional properties as opposed to developing what i have, because I’ll continue having that and can do what i please in the future. 

Will you be buying Miami?

you cannot realistically buy real estate when you have no personal funds.but what you can do is work to put a partnership together where you find a money partner and you guys do a JV  money partner you do the work.. this can happen if you find someone who takes a shine to you and wants to help U

It's a new home, so it should be as close to perfect when you buy it as possible.
