Living in the same house is a popular fact, but it might be a little dishonest. It's a big house, with a lot of space around it, and it's obviously been kept up to date with somebody who has money. It's not at all like the 50 year old house my grandparents have.
I'm not sure how dishonest it is, as I can't imagine he stays put in the house for PR value.
Beyond that, I wouldn't assume that he's had an incredibly out-of-the-ordinary level of work done on the house. It's time-consuming, disruptive and messy.
Adjusting for his budget, I can only imagine this would all be made worse if the upgrades include holodecks, teleporters and a subterranean command center.
