The load calculation made for the existing foundation were not factored into the initial design.

Of course, if you do flip it you'll want to put in nicer finishes so that would increase your rehab costs and that needs to be factored in as well. 

Run your comps and be prepared to adjust a suggested price based on condition, layout, and other factors.

@Isadore Nelson Yes, eviction is possible, but there are too many factors that need to be taken into consideration, active military family members, disabled veterans, building violations, maintenance issues and etc...

So most investors just throw in the same expense factors no matter the age of the property.

I think pools also factor in to summer rentals, if you don't have one that will hurt you. 

I base the price on a few factors - Room size, amenities and area average rents. 

The renovations were already factored into the LTV during the initial loan approval, and the increased value of the property due to those renovations may not automatically allow for an earlier PMI removal under Fannie Mae's standard policy.Workaround/Next Steps:Reappraisal: You might be able to request a reappraisal if the lender is open to it.

Factor in vacancy.  

Of course you can manage for this and set aside funds however I suspect the risk and loss factor was/is far greater than the sponsor realized when they go in for this noble pursuit of helping homeowners save their homes..
