Nothing is accruing between now and then, right???

WHich brokerage are you with out of curiosity?

Just out of curiosity...

One more question:  Besides the amount I would pay at the auction sale, how can I find out the amount of taxes owed post-judgement that could possibly be accruing?

This could be as high as 18%, per the statutory maximum from FSS 197.172(1) or, very often, as little as 0.25%.197.472    Redemption of tax certificates.(2) When a tax certificate is redeemed and the interest earned on the tax certificate is less than 5 percent of the face amount of the certificate, a mandatory minimum interest of an absolute 5 percent shall be levied upon the face value of the tax certificate. [...]Translation: When a property owner pays their delinquent taxes and thus redeems a tax lien certificate, if the certificate has yet to accrue a total of 5% at the rate at which the winning bidder won the certificate, then the winning bidder receives 5%.

Interest still accrues and some will require a lump-sum payment anyway.   

It's an amortized schedule, if you keep the loan that loan you will accrue a ton of interest.  

I do not, nor have I ever, liked to accrue a lot of debt.

@Josiah Swartz Out of curiosity, would you purchase this property (or one like it)?  

Laddered I-bonds or CDs out of curiosity?
