Hello Michael, that is exactly what we did three years ago. We got a HELOC for $196,000. We used $113k to buy a 1/1 condo in the up and coming Allapatah area near Marlins Park. We spend $17k to update it using our credit cards and Home Depot and Lowes 0% interest for 12 months. We chose an Interest Only option variable rate. It started at 4.5%, but it has gradually climbed to 6.61%. It cash flows about $400 every month. We rent the unit for $1,385. The HOA fee is $258/ month, property taxes are about $180/ month and the HELOC interest only is $525, but slowly decreases every month since I apply $400 towards the principal. The HELOC balance has dropped to $95k AND the condo has appreciated to about $150k. I thought of doing the BRRRR, but the refi was going to eat about $7k of the equity. Instead, I will probably sell it in 2-3 years after the HOA updates the building which will increase the condo values and as you may now, the City of Miami is spending $208 million for the I-95/ 595/ 836 project which I believe is going to create a boom for that entire area.
