[GNC] How to Properly Record Valuation Changes in Home Value?

[Tom Route-36]

Hi all,

This is more of a double entry bookkeeping question rather than 
something specific to GnuCash; but I'd appreciate any input on the 
proper way to do this.  I'm tracking the valuation changes of my 
personal home based on notices that I get every 2 years from the County 
Assessor.  When I was using Quicken, I did this in a single account 
(named MyHome).  The opening balance of MyHome was my original purchase 
price.  And then every 2 years as I got updated valuation notices, I'd 
record a transaction back into that same MyHome account (since Quicken 
would let me do that) to adjust the MyHome account balance to make it 
match the current value listed on the County Assessor's notice.

Now that I'm using GnuCash and having to do things properly with double 
entry accounting, I was wondering how to go back and fix things.  I know 
I still want an Asset account for MyHome to track the valuation.  But 
for DE accounting, what should I be using for that corresponding second 
account to balance things out as the valuation changes?
