$650,000 / 4br - 2000ft2 - LA (Angeles Mesa) Duplex!!!!!!!! (Los Angeles Mesa)

We have a duplex in the Angeles Mesa pocket of Los Angeles! Both top and bottom units are a 2 bed/1 bath.
We are a total of just under 2k sq ft on a 6500 sq ft lot w/ ALLEY ACCESS.
Our corner lot is zoned LAR2 and we also have TOC Tier 2 status which allows you to build more if you want to develop.
There's duplexes our size selling in the mid to high 800s!! There's an investor who bought a duplex at 675k that sold with a squatter.
Multiple exit strategies: as-is flip, buy and hold, value-add, or brand new development!! Bottom unit is vacant and boarded up.
We personally went out there to speak with the occupant.
She was very cooperative and spoke with us.
She claims to have lived there for 15 years.
However, we are told there was never a lease agreement in place.
She personally said she is open to cash for keys, however as of now, we are still working on getting a number.
