You’re asking the right question, and the answer isn’t cash or HELOC, it’s liquidity management vs. interest arbitrage.A few observations based on what you shared:• At a 12% tax bracket, the psychological benefit of paying off the primary residence may outweigh the tax math, since that interest is effectively non-deductible anyway.• However, paying off the house first and then relying on a HELOC introduces call risk.

In those cases, I’m effectively buying someone else’s problems at retail pricing, which is just not attractive for a savvy investor.

Most will not take the time necessary to effectively take careof your investment.Use Section 8 tenants as much as possible.

I will continue to analyze deals and educate myself daily, however, those activities have more of an indirect effect on my portfolio.
