With that the manager placed a mark down sticker on a darker piece of meat.

Maybe the first property had a lot of work done to it and you will not really see any major maintenance for the first 5-10 years (not accounting for tenant's mistakes) That might be a much greater payoff in terms of cashflow than a property that has a lower sticker price BUT needs some maintenance right away.

GFCI should also have a sticker that says "no equipment ground" if it is not grounded.

I have done some diligence on Parks exactly like this - the POH are a disaster and you're going to end up effectively moving all the POH out of there since they're already worthless and have to move in nice(r) ones so you can get better tenants and rent rates.Also when you're renting like that the area typically isn't nice and there is lots of crime, which means you have to spend money on fences and bushes with stickers to deter people that want to smoke crack in your homes when they are vacant.Capital intensive and cannot get financing.  

My rehabs have been in Oakland, although I have thought about going further afield and perhaps getting over my SF Bay Area sticker shock.  

WE ONLY HAVE ONE STICKER ON THEIR GARAGE FOR GARBAGE PICKUP AND I HAVE TO CARRY MY GARBAGE UP TO THEIR GARAGE, SEEMS I AM ALSO PAYING FOR BOTH HOUSES. 

Best part is that when tenants become accustomed to gradual rental increases, they don't get sticker shock when you go to increase their rents the following year.

Was there sticker shock of down time, remediation cost and rebuild?  

Ask for inspection stickers/updates and inquire in your town.

The financed buyer can pay a higher sticker price because most of it is financed, but takes 21-45 days to close.
