You either have verified income and meet the other requirements, or don't. 

I remember when I first started looking into multi-unit properties, financing options were such a headache, especially trying to balance affordability with down payment requirements.

What kind of seasoning is generally required as it relates to the rents/revenue as it relates to servicing the note, etc...I currently own one PadSplit (acquired via Subject-to) that has been up just over a month.

Most lenders who order appraisals are required to order them through a 3rd party AMC, which can add additional costs to the appraisal but ensures that there is no lender (Or borrower) bias in regards to the values.

You said public water was available...would the lots require a septic system to be installed or is public sewer available? 

I have been told by a contractor that the foundation of the building is intact, so it does not need to be torn down but requires a "gut renovation down to the studs."

Many of them might be skilled folks but they are not always the best estimator and business person. 

@Andreas Mathews admirable, but make sure you do some research so you understand what a PM can make.Starting your own PMC business will require 75-150 doors to make a decent living, depending on gross rents and your fee structre.Working for a SFR PMC as a PM, will require a RE license and you usually get paid a percentage of the gross rents the portfolio of owners/properties you manage generates.

I don't know if this is required in your locality but if it isn't get rid of it.

Social security number is definitely not required for non-payment for eviction in NJ.
