For example in many jurisdictions I can STR units in a duplex but cannot STR an ADU (some jurisdictions will let you STR if you owner occupy).

The property has 6 units with 5 veteran tenants currently occupying the place.

Seller Pre-Sale Financing: Consider selling the tenant-occupied property "as-is" now to an investor, perhaps at a slight discount, which could save time and eliminate renovation costs.

After 25 months, If they can prove that they lived in the property for two of the past five years, they can sell it as an owner-occupied residence.

Fannie Mae has a requirement that if you want to use the rental income from the non occupied units, that you MUST have a current housing expense which means you cannot live rent free.

Hello, due to a hiccup on my personal credit history I am having issues getting approved for traditional financing outside of an FHA which I do not plan to use as I am not going to owner occupy.

The concern with places like Irvington will be once you move out and no longer owner occupy how do you raise rents legally.   

They allow you to include up to 6 months of rent payments in the loan if you are unable to occupy the premises during the renovation.Just to be complete, it's also worth mentioning that both the VA and USDA have renovation loans.

The good news is owner occupying allows you to get away with things like this a bit more. 

I'll be in the market for a duplex/triplex in the $400k range that I will owner occupy and use a 5% down loan.
