I am a new real estate entrepreneur searching for multi family homes in SE Michigan.  

In conjunction with your own searches, network with a local agent (you can probably find someone on BP) by e-mailing them or taking them for coffee. 

Google and check out CRM’s like Realty Juggler, Ixact Contact, Lion’s Desk, Top Producer, etc etc.  

However, hiring a property manager also takes some effort and you should never grab the first person in the phone book or the one with the lowest fees.You can start by going to www.narpm.org and search their directory of managers.

I'd do a search for "Best Places to Retire" or "Where Millennials Are Moving To" or "Where Job Growth Is Highest".

Bigger Pockets is such a wealth of knowledge that it is easy to get somewhat lost.You can search forums by category and scroll through the most recent for interesting sounding topics or search for specific keywords.  

They must do a title lien search and contact everyone, #1 #2 anyone that may have an interest in the property.

The  association I'm in has a program we use that has these properties already listed there but in the South Florida area.But for you.....I read in the book Wholesaling Bible, "To get a pre-foreclosure list you have two options: (1) you can put the list together by going down to your local county government office and searching for and finding the recent lis pendens or notice of default findings; or (2) you can buy the list from a pre-foreclosure list provider/broker."

My Wholesale team is going to be flying into Miami from Canada this Thursday for Grant Cardone's 10x Event.We'd love to meetup with any local investors to talk shop.The three of us own nearly 100 units, have experience running a wholesale business in Canada and one of us has a YouTube channel with over 10,000 subscribers (Search Matt Mckeever on youtube to checkout his content)We'll be in town from June 29th - July 1st.

Your tax list and a google voice number can work.
