The source I like the most is from personal referrals.

The properties are owned under our personal names. 

Forced “partnerships” just have a very high probability of failure.The first thing I’d do is check out the buyers personal financial statement.  

I haven't went out to take a look in person just yet. 

Permanent debt commercial mortgages also generally will not play with an in-place DSCR below 1.25% (possible exception for very strong/experienced borrower, but such a person wouldn't be making a thread like this one, no offense. :).An interesting result of the 1.25% DSCR being more firm on the commercial side is that rent-to-price ratios and cashflows are better.

I married someone just like me.  3) I want a system that's as easy as possible for me to get receipts and information to the person doing our books.  4) our system MUST be secure. 

Personally I keep one account for each building and one account for security deposits.

I had a rental property that was running well, and my personality simply led me to sell the property.

Sounds like the opposite type of person you want in your asset.  

Additionally, I am pretty set on house hacking and this area due to a new job that requires in person work, where a sub 30 min commute would be ideal.
