Hey @Account Closed welcome to the community!
House hacking can be a GREAT opportunity, as many of us in these forums believe. Also, using a low down payment option can be a good tool to utilize leverage.
What area are you in? I don't know if you mentioned that?
If I was you, I would work on paying off that credit card debt, before you get into another large debt, especially if that $7k is high interest debt.
As far as savings/down payment, it is probably a good idea to have a emergency fund buffer beyond your down payment. On that same note, see if you qualify for any down payment assistance programs/grants. $50k per year you may be eligible.
Have you went through the pre-approval process? This is where a lender will review your financials and see how much loan you'll get approved for. This will give you a much better idea of how much home aka house hack you can afford.
Good luck James. You're in a great place to network, learn, and grow. We are all here to help!
