@Corbett Brasington I might be misunderstanding what you are asking here but I do no rely on a sq ft multiplier. 

I've also seen that there are some private and hard money that would do loans to foreigners but they seem much more expensive and they would probably kill the cash flow from the buildings i am looking into.The duplex I own I paid for with my personal line of credit but that limits my buying power by alot.The main reason why I invest in the states is simple, in my area in Canada, gross rent multiplier is about 16-20x, which is not ideal for cash flow.So my question to you is this: does anyone think that it's worth it to get loans with higher interest rates and just go with my initial strategy?

What you focus attention on multiplies. 

I feel like the finance fee's are canceling our current cashflow and the payoff calculator we are using for the Credit debt reads 7 years if we keep using our avalanche snowball method to the tune of 43k in interest paid over 7 years.

A side effect of a low cap is exactly what you are talking about - the multiplier of the value add is much greater, and thus it makes sense to do value add.

Your NOI at a cap rate puts you at around $1.6m-$1.7m, but if you look at a gross rent multiplier, it's much lower.

Cap rate, price per unit, comparable sales, gross rent multiplier etc. 

Take your ARV, multiply by your banks loan to value percentage, subtract your purchase costs.

I have invested in stocks most of my adult life and am hooked on multiplying wealth.  

On a 4 unit, appraisers will also use the Gross Rent Multiplier (GRM) to calculate value.
