Brent,
Your logic is sound. We achieved a debt-free lifestyle seven years ago. After which, our additional "pocket money" started the wife's retirement account and later, college accounts for the kids. We live a blessed life and the kids are well cared for but little excess remains for alternative, what some might consider "higher-risk," lest we pull a penalty-free early withdrawal from an IRA account.
Mike and Randy,
All that debt paid off years ago was consumer debt, including our cars. We do have a home mortgage, but we've only lived here two years, hardly enough equity to borrow for this BRRRR investment. Local lendors quote 4-5% APR and minimums of $50k. Private money lendors, naturally, offer even higher rates and short-short terms, but we may have a little better luck making that type of deal work. We would like to factor in a year's worth of mortgage payments into the loan amount so truly zero cash comes from our family budget, but lendors are wary of these crazy ideas.
