Do y'all have any advice relating to how to have more reliable estimates and how to find sub-markets in areas?

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Hey I did deep search in a lot of sub markets throughout different states.As I see, the average profit per average property is around $350 per month.Anyone else can confirm?

Yes, property managers you can goggle and do your homework and interview to see who you want to professionally want to work with for all of your real estate needs.

If you're considering investing out of state, my advice is to look for markets with growing economies.

If you want to network or ask specific questions about your local market, go to your local real estate forum and connect with investors from your area: https://www.biggerpockets.com/forums/86-local-real-estate-networking5.

Ignace, Michigan because you saw it on a list is probably a waste of time unless you have some sort of connection to that market. 

And is wholesaling still effective in this market?

Hey BP,Seeking some help on negotiating/offering a price to an off-market seller.I cold-called an off-market opportunity today and the seller expressed interest in selling if the price was right.

I understand how the rental market works.
