Final answer:
A property needing many obvious repairs is most likely advertised as a fixer-upper with potential because it needs repairs and offers a chance for buyers to personalize and potentially increase its value.
Step-by-step explanation:
If an open house is held on a property that requires many obvious repairs, it is most likely advertised as a fixer-upper with potential. This term is commonly used to describe homes that need repairs or renovations but are priced accordingly, usually lower than market value, to account for these needed improvements. Such properties offer buyers the chance to personalize the house and potentially increase its value through renovations.
Option 'b' Ready-to-move-in would not be accurate as the property needs repairs. 'c' Ideal for renovations could be a possibility, however, it doesn't necessarily convey the same immediate understanding to potential buyers that 'a fixer-upper with potential' does.
Lastly, 'd' A project home is similar to a fixer-upper; however, the term 'fixer-upper' is more widely recognized and understood in real estate marketing to communicate the state of the property and the investment opportunity it represents.
