I am soon closing on rental unit 4 and 5. First property 10% down Second 20% down with HELOC off primary residence Third same as second Fourth/fifth (a duplex) 25% down. Half heloc. First three cash flow and I expect 4 and 5 to do so as well. My question is what do I start to pay off first? Lowest loan amount first? Or maybe start paying down heloc? My plan is to try a cash out refi a year after I've owned one of the properties to gain money for the down payment on another. Man this gets addicting! I don't need my cash flow as I still have a day job right now. Please share your thoughts on where I should start. Or please share how you started your snowball effect. Many thanks!
