Turn Rental into Primary Residence for the HELOC?

[Wes Rice]

To avoid the potential of wasting more time in trying to figure this out all on my own I am humbly requesting help.  

I'm currently planning to move into my rental property in June/July 2021 in order to do some renovations and to take out a HELOC and start growing my portfolio. The HELOC would provide just over $100k to be used towards additional properties. My current lender only offers primary residence HELOCs, but is currently not accepting applications (assuming they will be by next summer). SHOULD I REFINANCE NOW WITH A DIFFERENT LENDER WHO OFFERS INVESTMENT PROPERTY HELOCs OR IS WAITING 8+ MONTHS ACCEPTABLE?

RATIONALE

- Current lender doesn't offer HELOCs on investment properties

- Favorable rates/terms on primary residence HELOCs

- June/July 2021 is the absolute soonest I could move into the home

CONCERNS

- Waiting 8+ months to start growing (missed opportunities)

THANKS IN ADVANCE!
