applesauce, we redid our bathroom couple years ago, and the old tub stayed for the same reasons as yours. It would be way too much to rip walls open to get a new one in (old one one could cut to pieces to haul it out). I really dislike the old tub though, and I am considering putting in just a shower. To me that would not make a difference buying a house, I like showers better, but then again I don't know how the "natives" here would think about a house without a bathtub (and we know we will sell this house eventually).
Our roof is fixed , it ended up costing $1950, and with a 10 year transferable warranty on craftsmanship that they will come to fix it if anything happens (hail damage, leaks etc.). I thought that was really really nice, and definately the reason why we chose the contractor. Next thing to do is to make the closet in den [where all water leaked in from roof before] to a computer nook/closet, can't wait for that one to be done .
ps. Have to add that the estimates for the roof were really ranging from the about $2000 to double that and more, so it was really worth it to get several estimates (although we ended up choosing the first one). I just don't understand how they can differ so much for the same job, same materials... Especially on a small house like ours. I could understand some 10-20% difference, but 200% and more is just uncomprehensible to me.
