The grass is not level and the fence in the back is not level. As far as I have been able to tell, it doesn't have any warping or sinking.
Also, today I found out I am going to have to come up with a bit of coin to install some electric baseboard type heating, or pay out the ass to have the furnace replaced. In the long run I will save more just going to electric, but now i have to get it installed, or I won't be able to get insurance (because the furnace is beyond old).
