@Mario Morales - As some others have said I think the strategy is sound, but the key would be to find a distressed property that you can drive up the value with renovations so that the new value is 25% higher than the purchase price so you pay back your HELOC.

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?
