On the other hand a line of credit might work for the down payment, but you will likely want to look for a private or hard money lender for the fix and flip portion and as a beginner, I would expect to put between 20-25% down and likely a bit more for closing costs and reserves. 

I've most often seen it with sellers who aren't interested in doing a 1031 and they save some on taxes, earn interest, have a swtream of payments, but no obligation to operations/maintenance. 10 years or less is likely.

The steps are the same, utilize credit cards, take out small loans, and make sure to make all your payments on time. 

Hello BP community.I currently make 125 k a year and I own 1 property that is performing well as an STR.I dont have the upfront cash to purchase another for a down payment but my parents are interested in financing my down payment with a 5% interest rate. 

I haven't done a down payment since 2015 and have 9 doors including my personal residence. 

But the power of a house hack is not from the cashflow after you leave, its in the immediate reduction of living costs you get while living there and the incredibly low down payment options you can use.  

I opened a HELOC on my main property thats in another state to pay for the down payment and remodel.

The interest only payments and great leverage should allow you to turn it quickly and reap your desired profits.

Or there may already be an assumption of debt component (It's generally non-recourse) as you'd see in a DST.A second option would be to use a zero coupon DST to absorb the debt in your 1031 along with 18-20% of your proceeds. 

The city posts the licenses to their portal immediately after the inspection, lead cert, and payment are all provided (again, through the portal).
