Could use some advice on how to handle this "foundation" issue before selling my home.

I am currently getting ready to sell my home, we are in the cleaning and minor repair/fixes stage. We have a small crawl space under a portion of our home that was an addition in the 70's. They made the foundation with cinderblocks and at some point it started to deteriorate (before we bought the home 7 years ago). It appears that someone has attempted to repair it from the outside as there is a large clump of cement directly against the foundation on the outside (there is a flower garden there now that has a large slope away from the home.)

This foundation is disconnected from the floor above it as seen in the picture that portion is being held up with the beam extended down to anchors in the cement pad underneath. The load-bearing walls are on opposite ends and those foundations seem fine. Essentially this foundation only holds up the wall above it (which has a large window) and a gable end.

We have noticed that after heavy rainfall the last few weeks that we are getting some water penetration. We have not noticed this in the past even with watering the garden outside the wall nightly so we assume it's from the heavy rainfall.

As we would like to maximize our profits from selling the home, what is the best way to handle this issue? Leave it and simply disclose it to the potential buyers? This concerns us because the house could get black-marked as having foundation issues and will scare off any potential buyers. I'm concerned about digging up the outside to try and waterproof it because of the previous attempt at repairing it leaving a large clump of cement that may or may not be a nightmare to remove.

The other option is to try and rebuild the wall in some way by either using hydraulic cement or the likes, but while I am extremely handy and have the ability to do just about any job, I just don't know what the best procedure is in this situation. We don't have the money to hire anyone to do the job, so it's going to be up to me. I'm hoping that someone with more knowledge can guide me on what path to go down in this situation.

Thank you to anyone that takes time out of their day to help!

I gather you are talking about water penetration below DPC level.

I would start by looking for pipes, drains and downpipes that might be the source of water.

If none found, trench the outside of the wall. If you can't find the source of water you can lead it away from the house with a French Drain.

But building standards, methods and regulations are different in our country.
 
That's not a foundation, it's called "oversite concrete"- which is not structural and it's common for water to appear there temporarily. The important thing is that it's ventilated adequately.

Unless there is a visible and accessible access hatch, the floor void won't be inspected on any buyers survey.
 
The reality is that the water table is generally quite high at the moment so it could be a non issue

The only issue I can see is that the timber supports appear to be set on timber blocks? If the water level were to rise further they could rot - consider replacing with concrete blocks, but doesn't look like any old damp/water marks but who knows the rate the polar ice is melting.
 
Dragoth Hi,

Unfortunately , I dont think there's much you can do - given your previous remedial attempt, the wet blockwork, the historic water stains, the possibly high water table - and the approaching winter.

Both the Home Inspector & the Termite Inspector will insist on entering that crawl space - if you deny them entry then you might be red flagged? S&L companies will then make difficulties for a potential buyer - & the red flag might follow you thro the Credit Agencies?

The Inspectors are professionals who will typically spot a cover up eg. hydraulic mortars.
So, its probably best to disclose?

Sorry - didn't realise the house was in America - maybe OP post on an American forum.
