Without knowing more details about the specifics of the project being proposed as it relates to your property, it's hard to say if there are any obvious big red flags that could negatively impact your property's future value.That being said, I would try to find out as much information as possible about the new apartment building's design and layout - the two big things I would try to ascertain would be the location of the garage entrances/exits, as well as the location of any outdoor amenity spaces (pools, terraces, dog runs, etc).  

I believe I know why the combined property value numbers are incorrect but still am not sure why the total loans, total equity, and total net worth are incorrect.For the total of the value of the properties, the amount of years of ownership being used for 2 out of the 3 properties is wrong, hence the incorrect scaling.
