Buying Two Fourplexes - Financing Options

[Paul I.]

Hello everybody,

I am looking at buying two fourplexes right down the street from one another. 

Will the bank look at this deal as a standard residential mortgage or will they view it as a commercial/multi family deal looking at NOI?

Also, in a situation like this how will the appraisals work? Are they off of comps or NOI/Cap Rates?

Thanks for the advise and guidance.
