"Just let me show you.

Supposing, for instance, that you want to build a house worth--well, say twenty thousand dollars, in some pretty town near the city." "I would rather figure on a cheaper house than that for a country place," I interrupted.
"Well then, say two thousand dollars.

You get masons, and carpenters, and people to dig the cellar, and you engage them to build your house.
You needn't pay them until it's done, of course.

Then when it's all finished, borrow two thousand dollars and give the house as security.
After that you see, you have only to pay the interest on the borrowed money.

When you save enough money to pay back the loan, the house is your own.
