16x28 slab in the back of the property that I "Fixed" now its a 8 inch monolithic slab with rebar and 1/8th inch wire for a foundation for a Attachable ma and pa unit.

This included new 4x6 beams and we raised the house a total of 8 inches to allow for access for the remodel and future crawlspace access.

In my market, where every square inch of land is in some sense desirable, you can lowball all you want if you write your own offers (no buyer's agent will take your business for long) but you will end up either buying zero properties for all your time and effort or inadvertently buying a liability rather than an asset 99% of the time. 

According to the International Residential Code, a bedroom window can be between 24 and 44 inches from the floor, it needs at least 5.7 square feet for the opening, and it must measure no less than 24 inches high and 20 inches wide (R310.1).Size: The room should be at least 70 sq ft, and more specifically the room cannot be smaller than 7 feet in any horizontal direction (sorry, that 1’x70′ room won’t work) (R304.2 / R304.4).

I thought you had inferred a few inches from water hence your statement about flooring and carpet.

However, for the plan to inch forward to action I need more information.

(hints at capitalizing) @Basit SiddiqiThe foundation sunk a few inches in the back, the repair was lifting the foundation with a jack system set in the ground under the foundation.

Depending on how low it sits you can regrade the yard or raise the house up a quarter inch (all depends on that specific unit).

Normal water pressure runs between 40 and 60 psi (pounds per square inch), and above this, the high pressure could be the source of water hammer.

Its not everyday people are willing to work with people they dont know like that, so trust me i take every inch of help seriously.
