On the cabin rents - other than keeping up with staining, appliances and new furniture- they are pretty bulletproof.

You can't get by with an underequipped kitchen and uncomfortable furniture.

I know it's possible to get furniture from many stores that offer "0% APR financing."

Hurricane Harvey...we bought in July 2017....spend a few weeks putting about $5000 in cosmetic touches and furniture into the place...then a week after that was done, Harvey tore part of the roof off.

That's the washer, dryer, fridge, stove, 3 bedroom sets and living room furniture.

Furniture left behind, etc.
