You should read through some of these numerous posts on this topic.

I gave Financial Freedom my credit card info so that they could bill me $3.95 to ship me a book.

I like to stay in the working class areas as they make enough to pay the rent and bills, but don't have the financial discipline to save enough to purchase their own home. 

I have to decide if im going to use a new injection of capital from the sale of my primary residence to:1) Hold in treasury bills at 4.5 percent until I find another property to purchase2) Pay off one of two existing mortgages, one at 3.75 percent and another at 4.5 percent3) Just find something to buy that beats either of those percentages on paper and be done with it4) Possibly loan out some hard money/broker it to a friend to allocateIts never an easy decision, but its a good problem to have.

In our company we basically use the cloud based expense reporting software that takes care of the accounts, invoicing and billing in a precised and significant manner.

From an investment standpoint this reminds me I believe of a Bill Cosby story line I believe.

I’m billed quarterly in Las Vegas.

Since tax bills are for entire parcels (typically, though not always) then it is highly unlikely that they somehow segregated the taxes for that small portion and paid it.
