Personally, If I could pull out a HELOC, I would use it to fix and flip which will typically make sense as you shouldnt be keeping the money out for that long and you can recycle it or pay it back and build off the capital that you got from. the flip.

Unless you are using your own money, then you shouldn't have a problem, however, if you are enlisting an investor or a lending company, and there are plenty to choose from, don't go with the ones who do the lowest interest.

You don't have to do anything with the money and there's no time limits or anything.2.

Their ability to recover their money should you default is much lower in this position.

Anti-money-laundering laws are largely to blame.  

Maybe they don't need the money now but in 5 years they wan to send a grand child to college.

Use your own money?

If its a Class C I'd go for a more affordable unit, there's no point in putting in more money than you have to. 

In those days it was possible to locate and tie up a “killer” deal, and close the transaction with absolutely zero of the investors own money.
