Make sure you choose a PM that does it full time and specializes in it and not on the side to shave a few percent off what you pay.

usually the cream rises to the top and aren't hard to find.contractors - please - dime a dozen.

This is the number one reason in my state of Georgia in most urban core and suburban areas you do not see new parks.They have restrictions against them and also the people at the park tend to be more transient.The local elected officials get constantly bombarded by complaints from home owners about the parks being eye sores and attracting crime.I have seen some counties enact laws where you have to buy a minimum of five acres to have a trailer on it.This keeps people from buying tiny parcels and dropping trailers on them everywhere and impeding the county and cities land use plans.I would look at a park where it is sitting on premium land for commercial development.I could sell off all or parcel out smaller pieces over time to extract more money per acre.My mom's friends in their 70's and 80's have owned about 45 trailers or so for 40 years.Every time a trailer burns down or something grandfathered in goes out the city hits them hard with paying for new connections etc. that cost thousands of dollars.Believe me cities and counties do not like these things in my state.There are of course rural counties where they do not really care about such things except for right in the town.The county or city will sometimes allow a temporary conditional use for a trailer while someone is building their house on the land but the put a time limit on it.

Just assume a long hold, the people who get creamed are those who assume continued fast appreciation to make their plan work.

I was also able to search around for PMI and shaved about $25/mo off of the original PMI my mortgage broker suggested. 

Our children know nothing else but being able to walk just a few feet from our door to buy dim sum, a burrito or an ice cream.

Also, since the 90's have you done any improvements to the house? 

Talk to a lender(s). Have

Good work and as long as you didn't get totally creamed on this, move on to the next and make a killing with your new knowledge.
