DEAR MR. MELTZER: After saving for many years, we have decided to buy a new home in a very fancy residential district. They are building $125,000 houses on one and one-half acre lots. Since we are the first family to reserve a lot, we can have our choice of 20 potential sites.

My husband thinks we should take the corner property because he says this is the most valuable. Do you agree with this?

ANSWER: If you were purchasing a commercial site, I might agree with your husband. However, I do not consider residential lots to be more valuable if they are located at the corner.

The old concept of corner houses being more valuable developed with the initial rowhouses that were built in the eastern cities of the United States. At that time, if you had the corner house, you had far more light and air than an interior house.

However, with detached houses on large lots there is no additional light or air for a corner house. But you do have additional noise from traffic, which now travels in two directions adjacent to your house.

What's more, you have the liability of maintaining two sidewalks and a lack of privacy. If I were you, I would choose one of the interior lots.

DEAR MR. MELTZER: We have a refrigerator that has a provision for installing an ice maker. We found ice makers for sale at a local appliance store this month.

Do we need special plumbing to install an ice maker?

ANSWER: The only thing you need is a very small copper water line connected to any one of your water pipes.

A plumber can do this easily. You may want to tackle it as a do-it-yourself project.

It does not involve any soldering, but uses something known as a compression fitting. This is installed by drilling a small hole in your existing water line and then attaching a fitting to this.
