It's not a big deal, once you find the source of moisture it shouldn't be too bad to fix.

That's step #1.Far too many people want to run a marathon so the first thing they do is buy some expensive running shoes, moisture-wicking shirts, a $300 fitness tracking watch, a $30 app, a 60-pack of energy gel, etc.

Hello Eli,The best way to inspect this is to hire a home inspector who will point out any possible structural damage and can also check for moisture throughout the property.

So it really only works from a cashflow perspective, not a forced appreciation play.Then you have issues with moisture, and often need to build expensive windows for legal egress points.You’d have an easier time forcing appreciation by looking for a 2br with an unfinished attic.

I'm not a fan of flushing agents, but 410a reverts to an acid at the slightest sign of moisture or contamination and makes a substance that clogs all of your components of the system and it's a royal pita to get that contamination out.

I would love to get a 70-80 % penetration rate. 

Moisture invasion gets more expensive the longer you wait to remedy it.

Why do you think it’s a $$$ fix for a moisture-ridden basement?

A few questions:Is this a (minor) moisture issue or a (major) standing water issue?

Another big issue up here is unresolved basement leaking/moisture problems.
