The end goal is to be fully dedicated to investing but there's so much to learn and I don't have the risk appetite to also quite my 9-5 to fully dedicate to real estate.I would love to learn more about investment deals and how I can find ways to fast track my goals. 

Only one bank account needed, but you'd have to track income & expenses to do transfer and year-end accounting.As @Nathan Gesner mentioned, not really worth it.You two could also open a joint bank account for collecting rent and pay expenses, just be sure to track everything.Do NOT do what @Paul De Luca stated about transferring title!

Make this your measurable goal that you track with your daily activity each day .. aka Key Performance indicators or KPIs.

Just wait until a sec 8 tenant fails to recertify or loses voucher and you need to evict these people who have barely any money/credit to find another place.

Platforms like CINC (Commissions Inc) and BoomTown are popular among realtors for managing lead generation and tracking and often support custom single-property pages too.

I have great credit, killer salary, and a bunch saved up but still can't afford a 20% down payment on anything over 600k.
