@Eric Jones - Amazing job being patient, I'd have given up after 3 tries.  

Look, we were for most part playing a game of American Football for a long time.

Furthermore, I fortunately had a visit planned to the US right around closing time so I was able to have everything notarized there.

We're looking to gather info about likely cost, pitfalls, time required, considerations when obtaining financing, etc. 

The book is already available on the website but I did not know that at the time! 

At times, we outsource as a result of time constraints or to leverage someone else's expertise.

You can use this property to hedge any others that you add that may only cover themselves, or require supplement until they are paid off.HOWEVER, if you have decided that your goal is to use Real Estate as a stepping stone to build wealth by upgrading the property you hold each time (condo to house, house to 4-plex, 4-plex to 8 unit, etc) then I think you are right to sell now while you think the property is at the top of it's appreciation.It will be hard for anyone on BP to tell you what to do as we don't know your goal.You are right. 

I spent a lot of time and money to learn how to structure seller financing deals.

This can 100% be done, but requires a lot of time, effort, and networking. 

If you are setting aside funds for capex, taxes, insurance, or other expenses that don't occur monthly, transfer those funds to Savings each month and hold them there until it's time to spend them.
