Hey Justin, good choice on the house hack, and in really big on Elizabeth.
With 3-5% down, you're looking at FHA, VA (if you're a Veteran), or some banks will do conventional as low as 3% down. Do some research on the positives and negatives of those to figure out which will be best for you.
For a first property, it’s impossible to say which is the “best” lender without knowing your exact situation such as goals, credit score, etc. So in the most basic sense, because interest rates are so low, the big banks may be your best bet. They can offer great terms, and assuming you have steady income, they are relatively easy to get.
At 17, a lot will be determined by the level of credit you've established up to now. Many 17-year-olds have little to no credit. Your first step is always to check in and see if you can get a loan. I would start at a local, community bank as big banks will be harder right now for you, being so young.
