What Is an Open-End Mortgage?

An open-end mortgage allows homeowners to borrow additional funds after closing, up to a set limit, mainly for home improvements. Interest is paid only on borrowed amounts, with payments rising as balances increase. Qualification requires strong credit, equity, and property appraisal. Though convenient, these loans often have higher rates and limited availability. Alternatives include home equity loans, HELOCs, construction loans, and renovation loans.
