Then, with mom acting the age of daughter , seemingly, she's trying to blatantly convince me that no one smoked in there.

The problem is that there are many out there who promote MLM programs unethically and even some programs that are blatant scams and when other companies come on board with similar a similar business model, they automatically get a bad rap.

Kirti, sorry you got taken advantage of so blatantly and so badly.

the fact that you didn't ask how to wholesale, how to house hack with an FHA, etc while blatantly just saying "I don't have enough for a downpayment" ....shows youre just trying to ask for someone to hold your hand and give you the golden egg on how to make it big. and I'm only being an A hole about this because I'm close to your age and most of my friends always ask how to do real estate with 0 self-motivation and research. if you really want to make it in this industry, research  and read Everything. then ask SPECIFIC questions

Your last statement “Regardless of how a landlord chooses to collect rent, they could experience the same thing that happened to you” is blatantly false (but I can see why you would want people to believe that). 

And because California is so tenant-friendly, it can be extremely difficult to evict a tenant who does something blatantly worth eviction, so good luck evicting just because you want them out.The only two options I know of for getting rid of a rent-controlled tenant are:The new owner of the property can pay one of the tenants to leave (amount is set by the city, usually somewhere ~$10k depending on different factors) if THEY (the owner) move into the unit themselves.

To me, it's an obvious, blatant flaw.

You are giving blatantly bad advice here. 

After being on BP for about 18 months now, one big thing I've learned is there are many topics that will have lots of different opinions on the exact same subject....there is no blatant "right or wrong".... only opinions.When it comes to rent increases you will get lots of opinions in the camp of "jump right to market rate and if they leave, they leave" and just as many in the "raise it in small increments to help avoid vacancy which is costly".

Thirdly, its comments like yours, telling people to watch their tone on a forum where its nearly impossibly to tell what the tone is unless it blatantly obvious, that make people more likely not to comment than me questioning a finance strategy that was lacking some key piece of information.
