Follow your process until it's over, don't negotiate or give an inch.

However, it seems to be built with less solid material than the main house and has very obvious tilt (two inches).

Only once, but I have seen it 200 foot wide after about 2 months of rain and then we got 5 inches of rain in an hour.There is very little "valley" here. 

April 2020 was the first full month of the pandemic, so the 37% increase in closed sales last month is a tell-tale sign that metro Austin’s housing market will continue to be hot for the foreseeable future.

Give an inch and they may take a mile. 

If it were mine (I might) go with this (if the neighborhood was nice).Some black mulch and some colorful flowers, a USA flag, and a bigger Black Rubber Heavy duty door mat.As well as ditch that tiny path of a sidewalk...I think I might get a "Better" Renter...

Worked on it with my parents over a 6 month period working everyday remodeled every inch of it.

If they don't keep it below 8 inches, your lease should state that you will hire it mowed and send them a bill.

From what i see they redid the house and it flooded about 17 inches on the house.
