I don't want to shoot myself in the foot by taking out this line of credit.

If you can do 4-5% down payment and have a decent credit score, most local lenders (mortgage brokers, credit unions, local banks) will be able to offer you a way better (overall) deal than an FHA loan.

I heard using line of credit for maintenance is what you should do.

@Joseph Blanchett, as military, traditional lenders will be tripping over themselves to lend you money assuming you have any type of credit history at all.

Its scary having this many credit cards but you also have more available credit.

My personal credit is mid 700’s and I was curious as to if anyone had any ideas about whether it is best to use personal guarantees or use your tax Id to establish business credit.

I'm also a grad student so my financial situation is not actually the best and I'am currently enrolled in a credit repair program (hopefully that helps with potential loans if need be) so I was thinking that maybe NACA would be a great start to purchase a multi family to house-hack and product passive income.

Talk with a lender about what your plans are and they will be able to look at your credit and financials and tell you if this will work and what the terms and conditions of the loan will be.

See all the 0% balance transfer credit cards solicitation you get in the mail now days?

My thinking is that because the purchase of a ownr fin. property doesn't show up on my credit, banks won't look at it as legitimate income.
