@Steven Stokes  no offense but how does one build a team with 300.00 ... that's ludicrous on its face... and you being in SF come on.Adrien Schebott  if you want ta career in RE  then the license is a great start.

Yesterday when I came to talk to him about raising his rent to market value $1,800 mostly he went crazy, he was offensive and very pushy, now I don't want him there not even if he paid $5,000 a month.

This seems like a terrible idea, no offense but if you have no clue where to start you're likely going to have a bad time with a flip.

The neighbor tried to sell it to a wholesaler who made a super low-ball offer which she found offensive.   

It’s just good to be aware of the laws as in some states the first offense is a misdemeanor and the second is a felony.  

High end black and grey work nothing trashy/offensive. 

That's the first line of offense against sound.

For example, If The seller is asking $37,500 for a 2bed 2bath but you found a 3bed 2bath In the same neighborhood, same upgrades, same features, etc that sold for only $38k, then you have every right to convince them their home isn’t worth $37,500 because your home is missing an entire bedroom and it’s not nearly as upgraded, etc. as the 3bed 2bath home.But, this is a dance so you don’t want to offensive to the sellers if you really do want the property. 

The best defense here is a good offense.

Filing eviction papers for a non-evictable offense could cost the landlord many thousands of dollars in a lawsuit.
