I want to build a portfolio of MF homes using creative financing (starting with one) then eventually scale to larger deals. 

Many larger lenders now bundle and sell their loans.

That was one of the larger problems I saw financing the property as being an "investment property" but I think your idea eliminates that. 

Questions to ask yourself are if you are able to service the larger debt payments on your own if the investment goes south?

I don’t really see an absolutely “wrong” choice here.

Which may not seem like much different but when you move to larger properties it can be a $5-7,000 difference which starts cutting into profits.

It wouldn't be that hard to get rid of them if you hadn't bought in NYC.....I know, your choice, just sayin'......

Wanted to make sure this was not something out of the ordinary that was a symptom of a larger problem.

Regardless of your choice, just remember that fear is part of the game and it's normal to have it but never let it consume you when the I's are dotted and T's are crossed, sometimes the only way is through so take courage and go on your way!

I am considering the possibility of selling 4 duplexes in 4-6 months and looking in to something larger.
