I read a story at the Glob of Mucous about Sears homes delivered by rail (in pieces) in the early 1900's. Prices ranged from $400 - $3200, and you had to build them yourself (or hire someone to do it). Cute little houses they were too. Sears would give a ten year mortgage on them with payments of $30-$40 per month. During the Depression, people did default on them. Now, houses, and the monthly payments, are 100x more.
Oh, sweet nostalgia.
Edit - I forgot to mention (from the article) -
The price was cheap. The materials were not. Cypress shingles, bronze door hinges, glazed windows, granite bathtubs. They came in styles and shapes and sizes befitting a wealthy farm owner. They also came in smaller sizes, at prices affordable to even an immigrant coal miner.
They carried evocative names such as The Montrose, a seven-room, one-bath Eastern colonial with green shutters, flower boxes and a hooded gable entrance. "Justly considered a beautiful home in any community, no matter how exclusive," said the catalogue.
Granite bath tubs - fergit yer granite counter tops - those are low-brow.
And the marketing was good then too - according to the catalogue. Evocative names. ...no matter how exclusive. No mention of luxury though.
