(The argument about "74% of your first year's payments going towards interest-only" is completely irrelevant, because if you converted the whole loan to a first position HELOC, your Lender would still require the same - if not more - money out of your wallet each month, and you'd only be accelerating your pay down if you were forced to pay it back quicker, or if you volunteered to, because of all your excess income!)

The city has a growing population, reasonable property taxes, and offers solid cash flow opportunities—especially with new construction duplexes.These are off-market deals that are designed to attract long-term tenants, and they offer a balance of immediate cash flow and long-term appreciation potential.
