@Rob Gervais I think you should reconsider renovating if you cannot envision what you want, or find someone they can help you.

When faced with those situations I like  to envision the worst case scenario and then ask myself if I could live with it. 

Without seeing the place its hard to follow / envision.  

Not what you want to hear and I don't have the details on your park so I could be way off base, but if it were me, I'd:-Get the homes up to the standard you envision for the park. 

buyers are envisioning entertaining next to laundry.

The appraiser will take a scope of work to envision what the property will look like post-rehab, and then do comps based on that vision.For conventional rehab loans like 203k or HomeStyle Renovation, I'd imagine they do the same thing as well.Still unclear whether this loan was conventional or short-term financing; it wasn't mentioned by the OP. 

I envision a family buying this as a bargain they can put sweat equity into at $1.05 million, and it will be worth $1.6 million after 4-5 years of them doing upgrades as they can afford it.

Its really tough to envision a good 1031 replacement.

. -  How do your envision yourself fitting into the process?

Not because anything is wrong but because they cant envision living there.
