For some, opening an account is required for the HELOC and may even be the difference between getting you from a variable to a fixed-rate option.Others try to get you to open an account before you even have the approval of anything – real slimy like, we won’t say any names on that.

There are so many variables to HVAC that can lead to problems.To your question, I would absolutely try to get the original installer back out to diagnose the issue.

The rate is variable, and is currently at 4.5%.

I also need it done quick so I can get my HELOC money back out of the deal as it's a variable rate and has gone up quite a bit.

After factoring in taxes (from your local tax assessor property search), insurance quotes, available cash for down payment and closing costs, and what mortgage you would have from the purchase price, and variable expenses (vacancy, repairs, property management, capital expenditures), and fair market rent, you're left with your cash flow number.

I heard Canadian market is all variable loans and with the rise in rates they could get hit harder in housing marketCurious to your opinion as I don’t invest there.

Is something like hometap a better option than a Heloc which would be variable interest.

Most HELOCs are variable interest.

It may be worth it, but there are too many variables and unknowns to decide for you. 

@Aubrie Caton in addition to the aforementioned banks, America First Credit Union was also doing HELOCs on rental properties as of about a year ago (I don't know if they're still offering them or not).As you probably already know, HELOCs are usually variable rate, and rates are increasing (and will likely increase substantially in the future), so it's important to be clear about whether there is a maximum rate the HELOC can go to, and what that rate would be....Once you know the maximum rate, you'll want to run a "worst case scenario" financial model where your HELOC goes to its maximum rate. ...If an investor isn't basing their decisions on worst-case scenario financial models where adjustable rates max out, then they're risking a 2008-style disaster where their formerly affordable monthly payment balloons into an un-affordable payment as rates rise.Good luck out there!
