I think it's long past time for traditional minded Catholics to face three facts. First, no matter how much you grovel and plead, if you go to a diocesan traditional Latin Mass you are living on borrowed time.
Second, while you still have that Mass it is an act of utter folly to spend money on restoration projects. Yes, fix the roof if there's danger, and get the boiler tended to but don't go beyond maintenance. Two times now I've seen good people take a run down church and lovingly restore it only to have a Cardinal, in one case, and a bishop in the other decide that they aren't allowed to have the TLM anymore. Essentially, these dear folks spent their time and treasure fattening frogs for snakes.
The third fact, may hurt the most. Your Novus Ordo attending acquaintances and family, be they wild liberals or do nothing conservatives will mock you in your grief at losing the Mass and the community you found at the TLM. They will also tell you to be silent.
Even if you have a benign bishop, and you can go to the TLM daily, he will retire or die one day and the next man up could gut you. Don't despair and don't become bitter. Talk to your spouse and friends about the worst case scenario now. If you were planning on moving across multiple states to be near a particular parish you might want to hold off and watch how the winds are blowing. You should take a road trip and see how far you can reasonably travel to get to Mass. You may have to content yourself to traveling to the TLM once or twice a year and going to the best Novus Ordo you can find for the rest of the time. This is what Rocky and I are doing and no, I'm not satisfied with it but it is the best we can do right now.
Admittedly this is going to be hard or impossible for people with small children at home or for those who can't drive anymore. While none of this is a fun mental exercise, it will keep you from being blindsided when one day your priest announces that the bishop is forbidding the TLM to be celebrated anymore. Like Our Lord set your face like flint and go forward.
