Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with zero or negative relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560, little to no good tradelines, lots of collections & chargeoffs, recent evictions.

Right now the rental income covers most costs and I’m going to be paying 600 a month of my own money. 

Seller financing is a great way for the seller to avoid a lump sum capital gains tax, and still make steady/expected income on a property even after they sell it. 

Also maybe turning it into a two family home to maximize rental income is an idea.  

If you want the income lending/lending funds would probably be a great option, but there is rarely any equity appreciation.

However, looking to leverage real estate to generate income and or future wealth.

House hacking is for sure the best way to get into real estate investing (in my humble opinion)If you combining your incomes puts you where you want to be, I'd do that.

Sure, what you do will affect those latter two, but nothing about the realtor.Perhaps with in your setup the lawyer and accountant may need to confer, but the accountant will prepare the return according to whatever income/expenses you provide and whatever legal structure your lawyer puts together for you. 

I think you may have very well narrowed down my strategy choices down to one of three; the BRRRR method (although this might be too much to start with for a newbie), the live-in flip that you mentioned (probably the most practical as I've been part of many different projects in the construction industry), and a combination of house-hacking/live-in flip (probably the most rewarding with a potential to swap between units as I finish one in order to bring better rental income).
