Can a cracked toilet be permanently repaired

One thing you can try is to shorten the chain to the flapper. Sometimes a long chain leading to the flapper will not allow you to open the drain fully (you are only lifting the flapper just a little bit). A partially lifted flapper will not allow the maximum volume of water to flow into the bowl in the shortest amount of time possible, causing a weak flush.

First off, never assume anything. You should take some pictures and know the basic dimensions of the house. You could talk with some local contractors, armed with pics and dimensions and get some ballpark prices. New siding on an existing building can go $250 to $400 a square (10ft X 10ft), removal and replace.

Just because your inspector found some rot, don't expect the sellers to discount for an entire siding job. You can try for what ever you think you can get, but I bet your offer to buy contingencies won't cover that. Unless the inspector committed and said the siding was unserviceable, you will need to negotiate.

Wood siding can last 100 years if well maintained, but I have seen 20 year old siding that was junk. The type of wood, whether the wood was back primed when installed, and how often it was stained or painted will make a huge difference.

Although this is not in a pure sense a home improvement question, I could not stand to not answer this one. I am a home inspector and these questions come up all the time with my customers.
