Before anyone can truly answer this, they need to really know what your short/long term goals are and what you want out of your brokerage.Personally, I’ve been a broker since 2004 and am with Berkshire Hathaway in Lincoln Park.

If you your plan was a flip or short-term hold, then a HELOC might be an acceptable solution.However, if your plan was to do a long-term hold, you will likely end up having to do two closings, one to buy, one to refinance.  

Would I have a better ROI doing Short Term or Long Term?

I am going to look into this, but thankfully I do not have such a case on my hands, else I would definitely not be a happy camper.Long story short, start planning an exit strategy with said tenant as this does not look/sound good.

Not sure if anyone is interested in possibly partnering or providing short term private financing.

Experience with nearly every type construction project long and short, always see it through to the end. 

Most of the bank can offer you short term like 25 years. 

I raced up there at 10pm on a Friday to find it 70 deg, and her standing there in shorts and tank top in February!

I ask because I came across a firm offering deals like this:Purchase, rehab and flip a distressed property, timeline 6-18 months.Minimum Investment $100,000Above $500,000 and an investor can appoint a member to the management boardMinimum asset price $1,000,000Management Fee: 2.5% of invested fundsManagement invests 10% alongside investorsDeveloper invests 10% alongside investorsSuccess fee of 50% on returns above 8%My main question is whether the 50% success fee on top of the management fee is highway robbery, or pretty standard on larger deals averaging 30%+ in such short timeframes?

I'll reach out shortly man!
