Understand resale and lending considerations

Off-grid features can affect how a property is valued, mortgaged and sold. This is neutral background, not financial advice.

How

US example: Fannie Mae, a major mortgage buyer, requires site utilities to meet community standards; where public water or sewer is not available, the property must use private or community well and septic facilities that are legally accessible and viable on an ongoing basis.
US example: Fannie Mae guidance also treats owned, financed and leased solar panels differently in the appraisal, and requires access to an alternate power source for some leased or power purchase arrangements.
Lenders in other countries have their own rules; ask several lenders early, before you buy, how they treat off-grid homes.
A full house file and final certificates make valuation and sale easier.
Some insurers ask about off-grid systems, wood stoves or batteries; check with yours.
Keep improvements permitted and documented, because unpermitted work can complicate a sale.
