Well, if the mortgage is simply a standard home equity credit, you’ll be extremely deprived from a tax perspective. The tax deductible interest you’ll claim would be restricted to the interest on the loan balance at that point.
By approach of example, imagine that you just had been diligently paying off your original $500,000 home equity credit for years and it currently had a balance of $100,000.
One day you choose to shop for AN lodging to measure in, redrawing $200,000 for the deposit and dealings out your recent place. Your new loan would be $300,000 however the deductible investment loan interest during this case would be restricted to the interest on the previous $100,000 loan balance.
This isn’t the simplest tax result.
