In fact I have not been in the place for some time. We were renting the place out since Papa did not want to sell it. He has been living with my sister and she told me that the tenant had shown her this problem. They call it subsistence, which means that we need to find a masonry contractor in Nassau county NY to fix the foundation. The cause is pretty simple, running water from a leaky pipe caused it to undermine the foundation. In fact you can look at the Grand Canyon if you do not know what water can do when given the time to work at something. In this case it can literally bring the house down if you let things go for a long enough. A plumber already fixed the leak that was causing the issue, but you have to find someone who knows what they are doing to fix the foundation.
I went and inspected the house as best as I could, while I was looking at this problem. We are going to sell the house at the right time and place. That is what makes the most sense, but no one can talk Papa into what makes sense and so it has to wait . In the meanwhile we are thinking about what is going to need to be done in order to get the best price when we do find the time is right. That means you want to fix the place up, but without using the money unwisely. It is a delicate problem which you need to think through in advance, or else you end up losing out on the chance to maximize the profit that you are going to make on the deal. They are not going to give you more than they have to.
