I work a W-2 job and still have a $13K of student loan, but no other major debt (own my car and small credit card debt) and I have a high credit score.I have been learning and researching on how to analyze BRRRR strategies in my area (Essex County, Haverhill, Massachusetts) but I am stuck on what can I do right now with not enough savings built up get and its only been 5 months with my FHA loan.. should I wait it out for the 1 year mark?

I also don’t like carrying debt so I want to pay cash for my personal residence.

Their goal is to find a 3 or 4 unit property and they will live in one of the units and rent out the other 2-3 units.Meanwhile, I have been wanting to get an investment/rental property and we're hoping to combine forces. 

I would also recommend a positive cash flow on day 1 of your ownership and do all expenses except the debt should be around 40% of the gross income. 

With that money (combined with my savings), I can enter the multifamily arena which is something I've been wanting to get into. 

A combination of phone calls, face-to-face meetings, and your own computer is what you'll be subject to at finding the information. 

The reason is my family business cash flows $700K+ net income/year and only has about 300k worth of debt overall (including a 13 unit apartment complex that is about 50% paid off) so I don't see any problem with getting financing for deals in the 100K-300K range.

If I use ARM for my first mortgage, at the time I buy the second property, how will my Debt To Income ratio be computed?

get rid of your biggest debt 1st then make profits you know?

So you may be able to do a combination.
