So now you know it may be worth it to consider a better grade cathode, or water filter/ treatment. 

I had to grade and level the entire property and plant new grass and it's now one of the prettiest lawns on the entire black.

If you have a property with a B grade or lower, you should always list it on their website.

Sounds good, happy to share a graded map of the area. 

I find it extremely difficult to give letter grades to an area.

Let's also say your daughter and your neighbor's daughter attend the same 1st grade class and will continue to do so after the sale closes. 

So I’ve since blocked off the third floor on one side and rented it as a 1 BR for now. but when the other side leaves eventually I’m starting to lean towards raising the ground grade 28” so that the total drop is less than 20’and then I’ll knock down some walls and make the whole 3rd floor attached only to that last unit so that the whole area can use the stairs and that window as second egress. 

@Peter Jin it depends on a million different factors other than the CoC.For instance, a 10% return on a turn key A grade property might be solid, while a 10% return on a C or D grade might be a nightmare.

Often, units that are sitting on grade will see deterioration of the cooling fins, due to animal urine or other contaminants, and physical damage, both of which affect performance.
