I currently have a pre-tax retirement account with employer match and a Roth IRA invested in the stock market.

Heck, there are even lenders that will NO DSCR, meaning they dont care what the income of the property is and they'll still fund the loan (at a lower LTV and higher interest rate of course).

Seller financed loans - See #2 above as typically seller financed have lower rates, longer terms and higher LTV.
