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

[gnucash at kcburns.com]

I have been following this discussion with interest, and now have a 
question:

My Balance Sheet (report) shows an Unrealized Gains line near the 
bottom, which is presumably my unrealized investment gains?  But, I do 
not find that I have an account named named Unrealized Gains... So, I 
wonder how this Unrealized Gains line works, and if I should tap into 
that process when recording the Unrealized Gains on my home?

I would prefer to keep these Unrealized Gains lines (investments vs 
home) separated, but have them appear one-after-the-other in the Balance 
Sheet (report).

Thanks,
Ken
