For this type of a question I would suggest posting it in the multi-family forum. 

Also, when they said they have "network" to find investers/property owner to land my offers, and "system" to calculate profits in order to show whoever owns the property short term rental is the more profitable option.

Starting with single-family and small multi-family properties is a smart choice, especially out of state.

I looked into trying to house hack in LA, with roommates or multi family but it just doesn’t seem worth it with the numbers. 

You might find that installing a mini-split system, properly insulating, and ensuring the finishes match the main home’s quality will make a difference in how the appraiser views it.

And you're right about avoiding weekly travel—sound systems can save you time and stress!

Stressed with lots to figure out in terms of getting systems in place and making repairs with not much time to get everything done, but I'm confident in the deal.  

House-hacking in a multi-family unit is one strategy I wish I had been aware of when I chose to purchase my first property.

Matthew,Am just starting to invest in multi family space, realistically up to 50 units.

Acquired a double lot for $112k after resolving title issues and paid $360k for construction, creating a 6-bed, 5-bath house designed for co-living or multi-gen use.
