We aim to balance thoroughness with fairness to ensure compliance.

You should aim for the longest Amortization you can get, CU may give 25-30 year?

So I had a windfall and can sort of "semi retire" with a part time low stress job. Part of me is considering buying more real estate though. I like the idea of being involved with and affecting the world. But the othe...

Seems like you are taking too long on the aiming.

In the future, we aim to get into fixer-uppers, development, etc., but for now, we like to only consider semi-stabilized (with minimal deferred maintenance) or fully stabilized, cash-flowing properties. 

Aim high, and have a great holiday season, brother!

Why not aim to move these perpetual renters into home ownership instead?

We aim to bring buildings and properties back to their heyday, at the same time providing affordable and middle income rental housing.

I like this train of thought and think you should aim for option 3: conventional loan + lower downpayment (perhaps even lower than 10%).

This ends up supplementing my income about $1,000/month give or take.
