You might want to consider long distance investing in a state with no income tax, like Texas, or a state with anonymous LLC's AND no income tax...Wyoming! 

There is likely an anonymous complaint that can be filed with the DRE with links to the Craigslist adds. 

I use land trust for anonymity purposes in which the beneficiary is a series LLC. 

This means (1) you get the favorable financing available in your personal name, (2) you can actually establish the Land Trust anonymously and remove your name from public record on the property [a great tool for those seeking more privacy,] and (3) still grants you the liability protection of the LLC. 

And it costs money to maintain the structures.Full anonymity vs no anonymity is your choice.

I am trying to send a reasonable offer than an unintelligent one.Any help is appreciated.PS: Some numbers are random to keep anonymity of this property

You can also call the SF rent board, explain the situation anonymously, and see what the say for free.

The operating company takes on all of the liability that would otherwise blow back on you including: paying property management, paying contractors, collecting rent, marketing, etc.5th pillar is owning everything anonymously.

When established with an experienced attorney, they can sign for your as a Nominee Trustee and keep your name off public record. this helps offer you some privacy through the anonymity of the property.

In our case, it just felt like another tax to extract monies for the city coffers.You may want to call your city anonymously and just ask what the process is if you bought a house and prior work was not permitted.
