@Nadya OstroffFirst thing is ALWAYS check for positive grade, sloping away from the house. 

My kids are little - kindergarten and first grade, and I don't even do everything for them.

Re grade drainage issues around houses .

My God....Such a simple question: would you pay to replace the neighbors fence, and instead I feel like I'm teaching a second grade class on basic reading comprehension and critical thinking, explaining the same basic things over and over again to you and ONE other guy.

I wouldn't pay an upfront fee at a pharmacy before they can help me.

I get the mid grade filters.

Damaged hardwood &/or laminate is going to be much more expensive to replace than contractor grade carpeting.Having carpet cleaned isn't that expensive. 

Here, they would not be classified as an over/under duplex unless the lower unit included the above grade main floor.David is also correct that they rent for less, even if they have a frost wall and are 50%-60% above grade, as folks do not like living in holes.

Things like foundation issues, leaks, moisture penetration, grading and drainage, mold, old wiring, corroded plumbing should have been addressed during the rehab.

I consider a Class A example to be an SFR or apt within 3 or 4 blocks from the beach or on the bluffs overlooking the wild life sanctuary which has top notch fashion up grades.
