@Ahmed Sublaban  Yeah you won't be able to get it online from the San Joaquin County Assessor's Office. 

Hi @Nicholas CruzI can't get all the questions answered at once, a tax lien is filed against the property, when you purchase a property the title company of the escrow office, or attorney, depending on who does that in your state, would require the seller to pay all taxes so you will receive the property without encumbrances, if you put a encumbrance on that would be a mortgage or a deed of trust.Respectfully,

Even though this  might not technically be against the rules some might think it goes against the spirit of the rules (in my opinion)  I am sure there are loan officers who will have a different take but truly the devils in the details.  

And with the internet, finding, researching, buying and selling properties is possible from your office in some cases.

I’m looking to network with other investors in my area and provide cold calling with a script, door knocking for wholesalers, sending out mailers, setting up bandit signs, or any other administrative office work in exchange for being in the environment of an active somewhat established investor.

I have at least $18,000 in savings and currently, have a w-2 student worker job paying $13/hour. 

The easiest and quickest answer is, you can visit the county and ask the tax collector or there assistant at the County Offices and they will give you a thorough explanation or if you prefer to work online you could research your particular county, I know your looking for Overages, in different counties they have different names, for example: In Texas those properties are called Strike-Off.

For it to be sent via certified mail you've got to go up to the post office & you've now got certified mail charges what is that like $5 or $6 or something, plus time at the post office for the employee.

Unless you share the wealth (pay them well), you get lousy workers.

Could be buying a 50% occupied office building (but with a big tenant lined up on my end), a run down industrial building (knowing the properties next to it are being knocked down and turned into a townhouse subdivision) etc.
