Keep in mind- you can pull your down payment right back out of the house through a HELOC, so it's not as if that money is gone forever, just don't buy beer with it- put it to work. 

I took out a HELOC on Condo 1 to buy Condo 2 (SFH) in Seminole, Florida outright for $55k (USD) in 2017.

I could take out a HELOC on my private home for a portion...maybe also a loan...but I think it would still be short of the necessary funds.

It has a HELOC used for real estate investing.

Yes I’m going to look into a HELOC.

Other Creative Methods Home equity — home equity loan or HELOC (home equity line of credit) (HELOC is renewable) — these loans are generally lower interest but the rates can fluctuate whiteout warning when things get bad Partnerships — you can cover each other’s weaknesses.

I know that PenFed offers HELOC's on both types of properties, but I wanted to know if anyone has been able to get 2 HELOC's, on 2 different properties(primary and investment) at the same time? 

Rent the property and take out a heloc to fund more brrrrsC.

I have a HELOC set up and am looking to use that money to do a BRRRR on a 1BR/2BR townhome close to where I live (I know I can probably find better deals further from home but am not comfortable going that far out with my first). 

A HELOC will be there when you are ready to pull the trigger when you move.
