As I step into this new venture, I would love to hear all insights and network with other owners in the same industry.

You can find one list on the Neighborhood Building Owner's Alliance website.

Hey Alan, Antoine here (owner of FlipSystem and MartelTurnkey).

I reached out to the owner and initially he wasn't interested in selling but i set a reminder in my calendar to reach out in exactly one year.

If your Register of Deeds is online, you can also search the owners name to find the recorded mortgage[s] against the property.

Thus, again, raising rents by 3% or 4% each year is imperative.Anyway, the PM told them it would be 10% a month gross rents, and the owners got very angry and upset. 

If I can convince the owner to hire an attorney that is. why would the owner hire an attorney?

I called the number on the sharpie marker sign and a few days later I met up with the owners and walked the property.it's a well maintained (on the outside) duplex on a large double-lot with tons of parking.

If you have trouble showing income and the property is non owner occupied, you may qualify based on DSCR 

Then you have the choice of paying on the previous owners behalf (which will delay foreclosure until they realize there's been a title transfer).
