My vision is broader: I'm investing in high-quality renovations to offer more comfortable, healthy, and affordable living spaces.

Some investors will continue to earn a healthy return on their investments while other will not be able to survive.

I didn't need cashflow to survive on, just as it appears that you have a healthy career outside of real estate.

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

The reason this is very dangerous is because not only does it impact your cash flow, but it also impacts your ability to exit as pricing is typically based off of the NOI approach.2) Natural Appreciation: Currently there is some healthy appreciation in the market, however, is that going to continue at today's rate for the next three years?

A healthy balanced market is closer to 3-4 months of inventory so we've got a ways to go.   

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.

At this point it may just be a waiting game if you’ve already offered a healthy price

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.
