ANY lender is going to want core soil testing which is expensive- where is this?

You can park car underneath and lock everything up when you leave.

If you have no experience in the construction field and have never taken on a rehab, then maybe it's wiser to partner up with a more successful flipper and learn from underneath them.

My contractor advised against doing LVT on the stairs (said it just always looks bad) so it seems like I’ll put carpet there (didn't want to do this but there's no hardwood underneath the current carpet).

Then if you ever go to sell the house you rip up the cheap flooring that has basically protected the hardwood floor underneath and refinished the hardwood floor to its best luster. it makes no sense to refinish the floors and get tenants that are going to wear and tear them down over years and then have to refinish them again in order to sell it.

These walls often have failures due to improper drainage or removal of water from the soil around the structure.

I spoke to three companies yesterday and they looked up soils maps and they believe our cost is going to be somewhere around $20k-$25k, possibly up to $35k if we need a special system.

But turn your front lawn into a junk-yard dumping toxic waste into soil, impacting entire neighborhood, no not cool.     

There was an old superfund in the 80s to clean up metal contaminants in the soil from the old mining activity, so maybe check into that if.

We were also about to put brand new LVP flooring throughout the downstairs when we noticed this issue....Recently, we had noticed the slope in our upstairs bedroom getting slightly worse, our window wouldn't close and it feels like some floorboards underneath the carpet are starting to come up so we contacted a foundation/basement company to come look at the issue.
