Start with your primary, rent out any spare bedrooms "house hack"Use that to practice upgrades, kitchen, bathroom, curb appeal... etcNow you have experience as a landlord and flipper, use that to buy a distressed propertyAdd 40% equity to the property through home makeover, refinance into a low cost mortgageNow you are cashflowing a healthy margin on a second property, use that to build equity over time, cashout later and buy your duplex/quad.If it's going to take you 10 years to save up a down payment for a small apartment building, yeah it makes more sense to start growing your portfolio with cheap SFR flips instead.Every market is different, every borrower is different, every property is different, it would be ill-advised to recommend anything without recognizing the individual's nuanced goals and objectives with their next acquisition.

The fact that our current rate is only 3% doesn't help the refi situation, as we probably would not be able to afford (or would at least struggle to afford) the payment on the new mortgage with the higher rate and principal.I think the best way to max cash flow would be with a small multifamily that needs moderate rehab.

But 3) Try multifamily specific brokers, crexi and loopnet, although 2-4 units maybe scarce. 4) A home equity line of credit is a good source of funds however it will generally make your overall monthly payments higher, so unless a deal is very solidly cashflowing, a HELOC may put you into negative cashflow. 7) Typically electric/gas are paid by the tenant - however this isn't true across the board.
