If my sister and her husband have anything done to their home, it will be for their enjoyment and they will not care about resale value. They are likely to die in this home. My sister just does not see that she needs anything more than what she already has.
We are about of the same mindset, but we still did a bit more to our home. Having the countertop changed was not that big a deal, did not take the workers that long, and did not cost a huge amount of money either. And we did enjoy it afterwards, and thought that we could have had it done earlier.
We have talked about redoing the bathrooms, but never got around to looking seriously at the options or having someone providing a quote. We just keep procrastinating. And I am afraid once we have it done, we will tell ourselves that we could have it done and enjoyed it long ago.
