I know where you're coming from about H finishing those tasks, but try not to get too stressed. My H did the same thing after he asked tenant to leave our rental apt so he could move into it. He told me he wanted to use the money he would normally contribute to his IRA to renovate apt. He spent the next three months coming up with things to do over there and changed his mind a million times. Replace cabinets, don't replace; Repaint, doesn't need painting; New bath vanity; New toilet; Sofabed purchase; New carpeting even though existing was only 1 yr old; New Kitchen floor. The apt was empty for 3 mos while he kept coming up with other things. I was totally stressed all the time this was going on, waiting for him to let me know the actual date he was leaving. Finally, it reached the point where there really wasn't anything left to do, it's only an efficiency apt. At that point I really stressed out thinking he has to make a decision, he can't leave it empty for another month without a good reason. And I think he was also stressed at the idea he couldn't put off the decision any longer.
Bottom line is that he's still here. Fate intervened and a friend called looking for an apt for the summer, the day after the carpet was installed, the last thing that he could do to it. I guess what I'm saying is back then with all his talk about furnishing the apt, and fixing it up, I was afraid I was a complete fool for thinking he might not leave.
From the outside, it sounds as if he may also be stalling by working on all of these projects. It may also be a control thing. I think my H got enormous satisfaction out of doing the apt stuff completely on his own, because he thinks I make all the decisions about the interior of house. I couldn't believe how excited he seemed to be about changing the apt. I think it was more about controlling his own space. This from a man who seemed totally uninterested when I would try to get input about doing anything in the house. It actually kind of pissed me off.
So, can you come up with any additional things that need to be taken care of. Maybe ask if he could fix some other things and see what the reaction is. He may be glad for the excuse to stay around, but unwilling to admit it even to himself. You might even suggest a new project, something that doesn't need fixing but that you have always wanted to change. Heck, if you have to, start breaking things for him to fix.
My H seemed to all of sudden find things he needed to take care of at the house about that same time he got into the apt - stuff I never saw as needed at the time. I think in his mind he was trying to do his fair share.
