but i've run into several issues when I apply for HELOC1. the home is a a rental and the banks/credit unions don't allow HELOCS on rental properties2. as mentioned the property is in the Northwest and I live in the southwest.

After the credit score is built I want to get an FHA loan for house hacking, I know that you need a job history to apply, but here is my question "Does the job history from my country matter in the USA as a 17 years old or in general as an adult for an FHA loan?

Do you have the credit score and credit capacity to qualify for conventional financing?

When you do a cash out refinance its cash in hand (liquid reserve) so it can be used as an asset or for PITI reserves on the next purchase.The other downfall is if your credit score should drop for any reason which can happen even my accident or mistake the lender will close or reduce the Heloc credit limit.

Local credit union financing.

The total cost of project is more than we can qualify for based on personal income, although our W2 income and credit score all work in our favor.

Their credit score is also slight less than the minimum credit score required to qualify so I can reject them based on those grounds.
