Some things mentioned do give me pause about BTD for my paver driveway and patio, especially the cost.
First, I would feel foolish to have LBYM and the just die with a large balance. What is the point of doing that? So, if the point of accumulation is to enjoy it, then that requires some thought on what would give me pleasure. I'm writing this while leaning against a rock while soaking bait fishing on a mountain lake where we've been camping the past few nights. It doesn't cost much but it is pleasurable as I listen to the wind and the soft quack of a mother duck to her ducklings as she spies me as she comes into view. I've done the caregiver thing for my father who had Alzheimer's and I've supported my children with home purchases and expenses when needed and appreciated. But at some time before I return to dust, I would like to BTD on something I don't especially need but think, "wouldn't that be nice?".
A deck, a boat, this paver project, trips, etc all were on the list, but only the pavers didn't jack up price over the past couple years the way lumber, travel and RV/boat toys have. Also, the only one that didn't immediately start devalue or wearing away is the pavers. The wear is even better than concrete which cracks sooner than later.
My conclusion is, after a lifetime of obligation to family and community, I am at peace choosing my paver project. It hardly makes a dent in my bottom line, will improve my home value and won't depreciate over the years like other home improvement projects.
