I hired him last year to help renovate a duplex for $45k.

@Robert QuirozI had purchased a number of duplexes and triplexes through the years.

You are (older/retired) and could benefit from house hacking and buying a duplex, or renting a room.

We have two rentals rent by room and a househack duplex.

This extra road frontage now also qualifies my property to be able to be legally converted into a triplex from a duplex.

Alternative route I chose, I will leverage my duplex (purchased 4 years ago) equity through house hacking to have skin in the game on next flip.

., "I will buy at least one single-family home, duplex, triplex, or fourplex before the end of 2019") and then do it.

I am also curious how folks are dealing with appraisals as appraisers don't view these properties as duplexes and I've heard of investors having issues with cash out refinances not hitting their target values where had the home been designated a duplex (lets say in a two detached property scenario) it would have easily appraised in their target value. 

This may affect value or time required to sell.7) Adding an ADU does not make the property a duplex.

Am open to single or duplex property that is requires minimum or cosmetics renovation.
