Sorry to hear your news
It might be a bit late in the season but you might be able to get some extra cash by temporarily renting out whichever house you are not in for short stays on airbnb. You can even rent out extra rooms wherever you are staying (if you have extra space). We started using it this summer to rent out our condo at the lake when we aren't there and have had really good luck so far. We allowed flexible rentals (e.g., 1 day or 20 days) and just charged a flat cleaning fee for each rental and wound up with rentals for every open weekend this summer as well as some mid-week and fall rentals (compared to 1 last summer with local rental agency).
