If you are working with a conventional lender, refinancing/ HELOC follows the same general process as a new loan (underwriting)...there are some exceptions to this, but it depends on the lender/loan product, and situation...

When comparing apples to apples across the board with different lenders you will need to know what the interest rates are, what % down you will be using, what the total lender fees are, any points being charged & what loan product specifically you are looking at. 

You will need to let your mortgage company know as the terms of the loan product could be dependent upon  owner occupied use or that of SFR rental alone, and you don't want to have anything come up there.

As in never.....Well yeah, naturally.

Relying on parking companies to manage and improve your "product" is paramount.

@Steven Wilson Thank you for sharing the the HML contact with me, ill be sure to check them out.They are really good with long term products, but dont expect it to be any easier then a traditional lender.

I work as a civil engineer for developers working on master plan communities, commercial buildings, and multifamily product throughout the Central Texas region.

I’m a overthinker my nature so just gotta scrap that and commit to it.

The DYI nature leaves me struggling to find larger quantities of plants and gravel at a quality price.

For primary residence, investment property held in my own name and investment properties held in an LLC, I'm interested to find out which financial institutions offer HELOCs and Cash Out products and the details for each.
