For another business I run I do post daily accountability in a FB/mentorship group and that does help me stay on track.

@Charles Perkins is absolutely correct about "collecting all receipts, properly tracking all income and expenses and your basis for all assets properly documented and recorded."

Life started moving fast as many probably can understand and I completely fell of track.

Now, I'm shifting my focus to multi-family properties, particularly in landlord-friendly states.

There sure are fast track approaches to this but really depends on strategy. 

Was it easier to dig the foundation with shovel, horse and scraper or with a track hoe?

When you have a proven track record of performance, then you can play with other people's money. 

This will be my first home purchase, and I am aiming to invest in multi-family properties.What should I be aware of when purchasing a multi-family property?

There is still a lot to learn but sounds like you are on the right track.
