Victorian stately homes for $25k and $29k and when I finish those restorations they should be worth $180k-225k after spending about $30-40k on their restorations/remodeling each.

Keep in mind that pricing is based off bedroom count of a voucher first and foremost. i once had a 7 bed voucher in a 3500 sq ft victorian, and i got 2012 a month (3 more beds than your voucher and the same money youre seeking). 

Another option, although I'm not sure what the ROI would be, is adding a Victorian-type porch along the full width of the front of the house.  

We looked into sub-metering water on a five (now six) unit building that was a converted Victorian house.  

They weren't gathering crops on a fenced property in Sacramento with a Victorian home on it and several outbuildings.  

I remember having wooden floors in all the rooms of our Victorian house growing up.

But I've always managed to find insurers.You can cover it with vinyl, but if you have a property with nice bones (say a nice, or even a middle class old Victorian) putting vinyl over it may throw off proportions of any attractive molding the building may have.If it's a property on Munjoy Hill/West End of Portland, you may want to consider remediation, as it would likely pay off in increased value/aesthetics/resale.  

Big time renovation issues, but depending upon the physical location and style (Victorian, Queen Anne), these can be gold in the ARV.

@Tanya RotellaA Victorian/Edwardian, or earlier, home with little to no insulation is common.  

These might not be considered the B neighborhoods you are mentioning but I would say Southern Orchards and Victorian Village would be closer to what you are looking for.
