IMO the BRRR or buy and hold method is a lot more forgiving. 

I'm not asking for profitability, I know how to run the numbers for that....As I said I'm asking about the price of the structure compared to other four unit buildings in the area there, and since it is a four unit you don't value it by commercial standards....

The con would be that it's a dying method of residency.

Structural Vs non-load bearing?

I know the building is a brick structure and it is listed as fire damaged. 

Once you decide what works for you in terms of what you can offer, then an acountant may be able to tell you a better way to structure it.

It's a loose goal but I like structure too.I've been successful with some single family flips but they are hard to come by (much less predictable in availability and actually beating out other investors) so I am considering some longer term real estate investing. 

Another common method our investors use is to sell one property with lots of gain and little equity and 1031 that one. 

The owners who offered the seller financing deal are very busy people which I get,but with my lack of capital or resources im basically sitting around waiting on them to make a move.I specialize in owner financing deal structures - what kind are you wanting to do?

Repayment structures can vary by company.
