I completely disagree.

I've been on jobs that have been very expensive ($50K plus), and looked
at jobs that were small enough that a few products from Home Depot and
the homeowner could do it themselves. In the end, the best idea is to
get a few opinions and weigh the options. The downfall is that a view
with the naked eye just isnt enough. Some repair look major that turn
out minimal, and vice versa.

Many times, the price of the repair can be deducted from the asking
price of the home, so everyone wins in the end.
