Kinda random question from a nevermo

So for context, my sister converted after marrying her second husband who is a TBM (at least as far as I can tell) . While my family doesn't dislike the guy we don't really love him either, he's passive aggressive, immature and insecure (they have to do absolutely everything together and are all over each other like teenagers). One of the things we've had a hard time understanding is the physical state of their house. Previously my sister has always had homes that are decorated very colorfully and eclecticly, she's always painted and done tons of DIY inside and out and it's always been cute and cozy and very reflective of her style. Her husband is very handy and has the skills to do pretty much any home improvement project but the guy cannot seem to finish one once started. They bought a house that was kind of a fixer upper and 7 years later it's in worse shape. She's had a bathtub in her living room that's supposed to go in the master bathroom for at least 4 years now and the deck is literally falling off the house. She's a dentist and he runs a fencing company so they can afford to hire out the work but he doesn't want to pay for it and won't approve the quality of work for anyone other than himself. But after reading a bunch of this board I'm wondering if the church demands so much time and money that members often end up not being able to maintain or improve their own homes, because he mentioned that he's always lived like this and that growing up (southern Idaho) they moved houses every few years. I know they gave 30k to the church last year and frankly that would buy a decent amount of work to fix up the house. So is this somewhat of a LDS thing (obviously it's also somewhat of a personality, in my opinion the guy is undiagnosed ADHD)?
