However, you'll want to repair/fill your cracks before you put down flooring so that 1) your flooring is laid on a nice flat surface and 2) moisture doesn't penetrate from the ground to your finish flooring. 

SO, would you mind please informing me of what I need to know (right after the part about starting with an experienced commercial realtor) What a realtors part would usually entail, what buyers should be doing.Don't be gentle.

Some of the old mortar is crumbling and there are spots with moisture residue (photos attached below). 

Mold, basement moisture that rusts the breaker panel, inspection difficulties, etc. 

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.

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