I imagine it can be difficult and complex given factors like zoning, septic tanks, wells, and a plethora of other things I have zero experience with. 

Besides being an over simplification of a complex and geographically diverse market, the information was outdated it as soon as he said it.Dropping commodity and energy prices have not caused the inflation that would have been expected in the past.It will be interesting over the next year to watch China will do about citizens exporting money as fast as they can.It is unlikely that the FED will want to pull money from other economies anytime soon.I am guessing the next FED minutes will say something like "We survived the rate increase, VERY slow ahead."

I am pre-approved for 1.4M range.Since I have multiple rentals (3) and Primary home mortgage, my case becomes complex with current mortgages 50% LTV .

Also the Universal Life thrust in retirement planning is a red flag, to me, because of the high upfront commissions involved and needless complexity often imposed in these products. 

OTOH I built and own the complex.

A track record managing a SFR worth $100K does not necessarily translate into owning a $450K multifamily property and that experience doesn't necessarily translate well into owning a $2M complex.

The area of real estate that resonates most is CRE note investing, which is so complex that I feel I would need to work to learn before I earn.

I'm self-employed and I own investment property so that's already two strikes against me for underwriting complexity. 

Large residential complexes will calculate a cap rate basically because they all will have similar expenses and share information so it is an easy calculation. 

My question is should I go and sell this property and pursue my goal of owning a small apartment complex or build a house which will prob cost around 150k to 200k and rent it out covering most of my mortgage?
