Most likely the issue is poor surface water management, failing gutters or missing downspout extensions.

@Abhishek Sahni, at the surface level, real estate investing is real estate investing.  

I know I'm fashionably late to the party (sips glass of bourbon).

I didn't specifically seek out anything like 30 year amortization or non-recourse, etc, so none of that surfaced.

Or it may be surface water flowing from another lot, or surface water piling up from rain and not soaking into the soil, which may be some type of backfill they had dumped in at some point during the construction process to grade the lot higher than it was when they bought it.

The rise and rise of house hacking might keep rolling considering that housing remains unaffordable due to high prices and low inventory resulting in an upward pressure on millennials headed for creative solutions like house hacking.Even though stylish nowadays, not only is house hacking in fashion but also bears enduring benefits like creating a property ladder, passive income generation, and financial freedom attainment.

That said, it sounds like the OP and their team have already been trying for months with many hours on the phone trying to resolve the issue the old fashioned way, and they aren't getting anywhere.

It is to create an easier path for a consumer that has been screwed over in some fashion.

Is there a driveway/patio/other solid surface near your house that would drain water toward the house?

Even if yuo do get a home in that fashion, just realize you are immediately over leveraged and underwater in most instances on that property.
