Re: replacing mixed foundation on Lake house with erosion
I would recommend stemming any current problems and leave the replacement of the foundation to the next owner. Normally I don't recommend such things, however, you will never recoup one cent that you put into this structure, so you need to minimize your expenses until you are able to sell it.
I am not suggesting that you jury rig the problem, what I am suggesting is that you strategically assess your options and go with the least invasive and expensive business model.
If a portion of the foundation is failing, then address that portion. You can replace a section of foundation easily enough without too much trouble or disturbance to the rest of the structure. If the hillside is failing, then you've got bigger problems than what's going on with the foundation, and no amount of structural work is going to correct the ground giving way under it.
