From a compliance standpoint, no. However look at your HELOC contract. You will find that all the termination, reduction, suspension, etc prohibitions of 1026.40 will be found in the contract. This will drastically limit your ability to reduce, suspend or terminate the LOC.
It is not wise to co-mingle consumer loan contracts for business purpose credit. Just my humble opinion.
