How much should I epxect to pay for a modular home?

I recently went through the same decision making process. As with most things, you generally get what you pay for and I've personally seen a wide range of quality between manufacturers in the modular market.

The short answer is that they're in the neigborhood of $50k to $250k. On the lower end you get something that may be as good as your average travel trailer (thin walls, cheap flooring, small rooms, etc.). On the higher end, you get something that, in my opinion, is of much better quality that the majority of on-site stick built homes. Your best bet is to stop by a dealer and look at thier models and price sheets.

The biggest benefit to going modular isn't necessaily price, but the fact that you will likely be able to move into it much faster than if you go with a house that is built on-site. Be aware though that modulars, whether they deserve it or not, still have a stigma about them when it comes to banks, insurance companies, and real estate agencies. They tend to lump them into the same group as "mobile homes". On the contrary, builders such as Silvercrest out here on the west coast build better quality homes than any tract house I have EVER seen - but you do pay a premium for it.

Also keep in mind that there are various manufacturers throughout the country and you'll have to look at the ones that are within delivery range of your area.

It depends whether or not you plan to buy one that has been hit by a tornado or not...

It really depends on the options you want. Thus the quote. They also need to know how it will sit on the property... foundation with full basement, footings, blocks... whatever.

You can spend a little or spend a lot, it depends on your taste and what they charge you to fulfill your dreams.
