I'm considering repurchasing a dump that to me was the Taj Mahal. Have
an appointment with my realtor to look at my old place today, which I
haven't been in in exactly four years. Just wondering if anyone here
ever did this "twice in a lifetime" type thing, and if they had any
tips, regrets, suggestions.

FWIW, I learned how unconditional love for a home could be in the years
I've been away.
