John Bianchi’s free course, which is about 30 hours long, is super helpful for anyone that’s trying to figure out what property to buy and how to design the property in a way that will allow it to be highly competitive in its market.

But using a HELOC is a risk because a) the liability is against your primary residence and b) current interest rates on HELOCs, which typically adjust after the initial term, are anywhere from 8-12%.

Is there a way to achieve both without having to give up all of the properties in the long run?
