HELOC Tips
- • Tax deductibility: HELOC interest may be deductible if funds are used to buy, build, or substantially improve your home (consult a tax advisor)
- • Rate caps: Ask lenders about periodic and lifetime rate caps to limit your exposure to rising rates
- • Annual fees: Some HELOCs charge annual fees of $50–$100; factor these into your total cost
- • Freeze risk: Lenders can freeze or reduce your HELOC if home values drop significantly
