I don't find it hard to believe. I'm no contractor, but we've been renovating our home for the last 10 months for the 2nd time in almost 20 years, and I've learned that everything costs twice as much as you think it will by the time it gets done.

Put together a spreadsheet listing the everything you think you need, and then go on Home Depot or Lowes and cost them out. Don't forget to add tax and delivery charges.

Have you considered using reclaimed and salvage materials?

I would expect significantly more than that, but it all depends on what you are looking for of course. If you are able to find things at e.g. a Habitat Restore or something like that you might find some good deals, but reclaimed materials often cost more than new.

@Harmoni: yes of course it all depends on where the materials are sourced. If Lisa is willing to put in the time and effort, she may find some great deals on lumber,roofing,bath fixtures,windows,etc. It also depends on whether she wants everything new or prefers a wonderful old, weathered look.

Google "tiny houses". We did an estimate for a 8 x 24 ft home and the materials from HD come out to around $15,000. This includes a microwave, refrg, sinks, water heater, shower, toilet and all electrical. If you would like to have a copy of the spreadsheet let me know. gary@clearled.biz

Wow! Thank you so much for such a detailed response. I really appreciate it.

This is a habitable but no electrical or water. It will be used as a bunkie. I am going to see if I can source at Habitat etc... Thanks to all of you!

Habitat for Humanity:: Here are some images of homes for the homeless (home4less). Just need a common area with bathrooms and a kitchen. Enjoy Life Daily~

just had another thought. shipping containers. no kidding. google it. people are turning them into wonderful living spaces.

We did think of shipping containers but our property will not allow for delivery where we would want it located. Property is rural very hilly etc...They do look like a great idea though

Shipping containers still need to have walls build inside for electrical, water, sewer and insulation.

@Lisa > If you are building these homes for charitable causes I wish to offer my services regarding no-cost housing options to assist your efforts without a fee. I have 45 yrs in the construction industry.

No this is actually for personal but the tips in the thread probably led you to think otherwise. Thank you so much anyway...your very kind.
