Before I start, I have not figured out how to @ (mention) someone, I'll take some instruction for that part as well...Thank you Chris for the suggestions on finding contractors.  

The seller is, in California at least, required to present the written offer barring other instructions from the seller such as "do not even bother showing me lowball offers."

You are not allowed to use arrest records to determine a rental applicant’s qualifications.According to the U.S Department of Housing and Urban Development: Arrests records are not a valid reason to deny a rental applicant housing.Convicted criminals may be denied housing if the reason for their convictions clearly demonstrates that the safety of your residents and/or property are at risk.Blanket terms in your screening criteria that say “Any criminal convictions will be denied” are now considered discriminatory and in violation of the Fair Housing Act.If you deny a rental applicant due to information found on a public record (like a criminal background report or eviction search) you need to provide the applicant with a denial letter and instructions on how they can obtain a copy of the report.

Every now and then I notice a profile that is hidden.

(also make sure there isn't any hidden surprises on the property, my local Code Enforcement department, Planning and Development department... 

Been flying for 16 years, just never did anything with it outside of instructing.

It comes down to the obvious of buyer beware since the unit was not hidden or disguised to pass inspection.

section 13/14 take care of what you have to do. 13 basically says you have to pay like 75% of their gross income x remaining months of the original contract and any options (2x7 yr options).14 tells you how to opt out of the options by sending a notice (gives you the time frames and instructions for how to submit notice). 

I set up a rent collection only bank account and gave instructions to all tenants that they need to deposit their rent at the bank and text me that they did.

Would love to chat with you but it says your contact info is hidden.
