As the lender I was issued a lender title insurance policy but I am not sure if the buyer got one too.So morally I actually do owe the taxes but legally it seems that my buyer ( because of his attorneys mistake) now will soon have a tax lien on the property.

https://www.njconsumeraffairs.gov/regulations/Chap...Look at page 15.I think Jared is likely correct -- this is probably more about getting something to base scope upon, not a licensed architect legal necessity.   

I believe this "subject to" is the way I will go as long as I have a good legal contract to protect the seller and myself.

In theory, I believe you should be able to rent out STR in any complex in California, regarding of HOA rules, so long as it is permitted with the City.Your best bet is to seek legal counsel and run the Oxnard case by them to seek their opinion.

My credit is over 800, along with a strong financial background, so I am not worried about getting approved.

Would I be able to legally rent out the property to 4 different families?  

Instead of a prospectus, companies will need to issue investors an offering memorandum, which is a legal document that is not pre-cleared with the regulators like a prospectus would be.

How long it will take if I go with legal action?

I work for Stewart Title, so of course I approve of this! 

@Doug Pretorius I like to check previous transactions on a property as well as any potential liens or legal actions from the city, etc.
