Any suggestions or advise on HELOC’s are greatly appreciated as well. 

No sure about that as buyers want to see the finished product and showing them before pictures will often not be well received.That's funny, my wife said the exact same thing about showing them the before pictures. 

The inspector for the buyers stated "this is a nice house" "done really well".

At some point if you're doing well, maybe turn the first one into STR or LTR, and do it again.   

Could you do a cash out refinance of that property and rent it as well, or are you planning on selling? 

I would also join every FB group for investors, from local to California, and post the package there as well.

Check Furnished Finder, Zillow, as well as AirBnb and VRBO (30+ day stays) to see what sort of competition is in that specific market.

@Rene Hosman As a property manager with 20 years experience and a portfolio of 1,000+ single family homes, I can say concessions like reduced rent rarely work well for smaller landlords.

Only if it looks well off from otherwise projections would I worry something like hotel listings might be throwing it off

Are any of the accountants you have looking proactively for tax planning opportunities as well?
