I am living in the San Joaquin county in California and noticed I am unable to receive specific information on owners.

We received two full price offers after the first open house!

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,

You can always cancel eviction if she vacates, so start it unless you're willing to risk even more months of unpaid rent.As far as last month's rent, get used to not counting on receiving it as many won't pay last month's rent as they need it for the next place's security deposit. 

We just received a bid that drain tile in our basement will be around $9k.

You will want to ensure that you will be receiving the duplex in the condition it was in (or better) at the time your contract was executed. 

I once had a property management company charge me $45 to deliver a letter to the tenant advising them that the PM would be entering the residence the following week.That same management company also had an early termination cause in the contract.Now, this may be local to my area, but I soon after received some wisdom from a few other investors.

I received 2 offers and decide to counter the higher bidder.

BUT if you must do it, then, just get one of the families of your trustworthy friends, or, relatives and have them move out there, after receiving some intensive training in hospitality, to manage the small 60 units for you and take a risk!

Stephen, you have taken the first step and you have received some solid advice.
