Take out a HELOC (some banks go as high as 95-100% LTV) to fund your next deal.

Find a property that you can use the funding from a HELOC from to do a BRRRR, once you pull the cash out from the BRRRR property pay the HELOC back for peace of mind.

One thing to note, with a HELOC you can only take out up to 90% of the home's appraised value. 

My question is should we utilize a HELOC on the Multi family, and use that to cover the 20% for a convential loan, or would we just be able to acquire an FHA loan for the new house? 

A heloc is another option that does not have closing costs and can be used repeatedly.  

We want to invest in another fixer property and want to use the HELOC so we can pay cash, fix it up and rent it out.

We plan to use heloc money on our personal home to pay for the down payment, and plan on using conventional financing for this deal.

Can somebody please clarify the HELOC for me, please?

But more importantly it gives me access via a heloc to a large sum of money should I find another good deal so that I can tackle that deal without needing to use hard money loans and their insane rates.  

I'm still learning how to find hard lenders, which banks to talk to and win, how to refinance, and when I can receive and use a HELOC.
