Obviously it is neighborhood specific but for me and every ADU client that I have where they rented both the house and ADU, they never gave a discount for the main house.

. - Forced Apperception (BRRRR or buying at a discount) is also a hedge against corrections.

Definitely a discount but I don't see a third or a half at all.

We use Quickbooks Online for our main accounting software.  

The house I am looking at is a private sale from an older family friend moving into senior living (discounted).

Consequently you either sell to the least qualified owner occupant imaginable, likely pay 6% seller assist, get crushed through the home inspection process or come to the conclusion going through that process 4 times is not worth the hassle and find an investor to purchase the homes as a package at a discounted price.

He focuses a lot on automation & software to get more deals.

I will look into driving for dollarsWholesalers just want discounted deals.

Quote from @Elizabeth Rose: @Josh Bowser this tip of doing a quick search on county GIS or software to see if homes in a neighborhood are owned in personal names or LLCs is gold, thank you!

I have 3 right now only because they got a new listing discount.
