When the market started to crash and prices dropped the banks either froze or lowered equity lines not giving you access to your equity.  

I see you are in NC and if you have access(you can also join if a direct relative is a state employee) to the State Employee Credit Union I would recommend them for your first home purchase as they will do 100% financing for owner occupied and no PMI which is what I am assuming you are doing with this purchase as a house hack.

As a vet, you have access to VA loans which means you might be eligible for extremely good financing.I wish you the best!

Good access and exit are very important as well as good cash flow.

Wife is a Keller Williams Beaches agent, so we have MLS access.
