I understand that there is data to shift through in regards to this, but I'm curious how it's been in your personal experience: as far as demand/occupancy goes, what are you seeing in the larger vs smaller properties you own? 

With the numbers people throw at me, in my area the TLDR/conclusion is most often that ADUs do not seem to make sense to build purely from a resale value perspective.

I'll offer the perspective of global nomad.  

The economy is about to shift very soon and that could change tour options... knut for the good or bad?

Jason,  here's the old guy perspective. lots of good advice on here, I'm 62 closer to retirement age, I went the SDIRA route with my accounts,  Buying and holding properties in the IRA ,  building tax deferred income  and purchasing houses inside IRA about every Two years. mine are traditional Ira's , Agreed i don't get to hold the money in my hands but it fully remains dedicated to real estate and keeps me on focus.  

From a personal perspective, we only look at pet-friendly STRs when we travel.

From the perspective of someone who hasn't yet invested in self-storage but is looking to start, it's nice to hear from those with experience instead of simply relying on data/analytics.Chris

The different perspectives is super helpful for a first time landlord for our home!!!

Unfortunately you will not get the value for the ADU (from a price per sq ft) perspective, but you will get a great value for the duplex.

@Aseel YerunkarThanks for the response Aseel, I agree you should always have a plan B to shift to.
