If I could go back in time the only thing I would have done differently is selling my home just before the bubble popped, rent for a few years, and then buy the house I'm living in now.
I bought my home in my early 30s which was an excellent age for a first home, paid off my 30 year mortgage in 15 years, lived there for another 20 years, moved out of state in the mistaken belief I wanted to live somewhere else, came back a few years later and with all my savings and proceeds from the sale of my first house I bought the house I always wanted to retire in, my reward to myself for a life of working hard, living frugally, and being smart with my finances.
Selling during the downslide from the bubble is silly of course, you have to be lucky to do that or be able to foresee the future.
Everything considered I wouldn't do a thing differently. Even the sojourn out of my home town taught me that you have to consider both the pluses and minuses of where you are living before deciding to move. I had only considered the negatives and it took me 4-5 months to realize I wanted to live where I had my whole life all along.
No sir! I wouldn't do a single thing differently!
