@Dillon Ransome many if not most areas have property records online so you dont have to actually go there. 

After researching online I found landlord responsibility under California Civil Code section 1941 described as followsClean and sanitary buildings, grounds and appurtenances (for example, a garden or adetached garage) which are free from debris, filth, rubbish, garbage, rodents andvermin. 

Then, for some of the other units, I would say, based on your message, it is safe to say that they would need rehab to get full market rent.

Personally I think it can be done online.

Sounds like being super proactive by picking out a place before selling the old one is a safe bet.

Is it possible to find something like that online (Costar, Crexi, broker websites, etc.)?

There's likely options out there for your refinance when you rehab it (minimum around 50-75k loan amounts).You can find private lenders online or you could possibly meet one at a meetup.

Goes to emphasize, not to believe what you read online-go to the state website and see if changes are coming...I doubt it.

When you say online advertising, I assume you mean off-platform? 

Not sure where to post this, so if needs to be reposted somewhere else, please let me knowI am trying to determine the value of a property as a STRUsing the online services, it comes out to an income of $110k+ at 67% occupancyOf course that must be net, so what does Abnb etc charge, whats the expected net?
