An off-grid budget is a complete list of what you must build and what it will cost, not a rough guess, because under-budgeting is one of the quickest ways to run out of money mid-project.
What you are paying for
The book says off-grid living needs significant spending, because everything that makes a home comfortable and safe has to be set up by you. It names four necessities you cannot skip: electric power, a water system, waste handling and a food supply. Costs depend on location, climate, energy use and whether you hire professionals or do the work yourself. A minimalist cabin with a few solar panels costs far less than a fully equipped homestead with food production and livestock.
Build the list, line by line
The book's most effective advice is to sit down and list everything you plan to build and the resources needed. Typical headings, which it also uses in its own breakdown, are:
- Land
- Housing (cabin, tiny home, prefab or other)
- Solar system and batteries (see planning a solar system)
- Water system, such as a well or rainwater (see water storage)
- Septic or composting toilet system (see composting toilet planning)
- Heating (see heating considerations)
Include the small things
The book says to factor in details that seem minor at first, such as delivery, installation and ongoing maintenance, because they all add up. It also warns that cutting corners during the build only costs you considerably more later, when you have to fix the mistakes.
Remember the land trade-off
Cheaper land often lacks infrastructure, so what you save on the plot you may spend on access, water and power. Compare total cost, not the asking price alone (access and roads).
Use your own numbers
The book gives broad price ranges in US dollars, and it notes they vary with place and style of living. Costs in your country will differ, so get written local quotes for each item, and keep a contingency for the things you will not foresee. Check which grants or incentives for renewable energy or rural projects exist where you live, and consider paying for advice from a financial adviser who understands rural property and local tax rules.
A simple process
- List every item and who will do it.
- Price each from local quotes.
- Add delivery, installation and yearly upkeep.
- Add a contingency.
- Decide what to build first and what can wait (making a transition plan).
