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.

@George Deantry zillow api http://www.zillow.com/howto/api/APIOverview.htm here is an example vba - http://johnmann.me/excel-zillow-api-extraction

A franchisee type tenant can go boom and bust so you want rental increase every year to extract maximum income otherwise they could last 4 years and then go out leaving you with flat rent.Have it as a REQUIREMENT to provide ongoing audited sales.

The more active control you take over all aspects of your RE investments, the more value you will be able to extract from your properties, at least in the early days. 

Its been highly profitable for Texas but this is what I seen working in various parts and being there TDY.Texas:Low cost StateLow tax StateExport driven economy historically (extraction and agriculture industries)When the economy started changing in the 1970s Texas got out in front of it.

@Dave Foster thanks for the reply, my goal is to delever my current portfolio, by extracting equity from my current house at a given interest rate to arbitrage business interest rate will not serve that purpose though it would help with overall cash-flow midly. 

It's a bit of a game - find the cards that offer the most value for your situation, extract all you can from them, and be prepared to dump them for a better offer if one comes along.

It more than pays for $250k each costs....so this investor extracts his original $250k, able to "repeat" and buy four more in the next year....and could actually have $50k extra profit in his pocket.

We want a discounted property (10% below retail would be real nice) in a decent area that projects at least cash neutral and has a value add that allows us to extract most of our investment back out after the refinance while having increased our equity position (BRRRR). 

I just purchased an out of state rental this month and want to extract the down payment from this investment condo.I'll put it on market in March 2017 and do a 1031 exchange with 2 out of state properties.
