This question crossed my mind recently after reading a post and some comments discussing whether an investor is experienced enough to raise capital from outside sources.

Does anyone recommend knowledge sources on building a mobile home parks (websites, books, organizations, plans, etc..). 

A warranty can bring peace of mind, especially if the tenant values quality and reliability.Here’s our rule of thumb:For budget-friendly rehabs: Used appliances from a reputable source can be a smart choice.

So the problem is you wont be able to source the down payment as coming from the seller (most likely), but you can certainly add as many junior lienholders as you like, after the fact.

I stopped reading after reading your subject line...know this:The #1 reason why landlords fail is due to their failure to manage to the lease (Source: American Apartment Owners' Assn). 

This is the sum of all of the sources of gain including not only cash flow and appreciation but also depreciation and amortization of the loan. 

Is there a reliable source to get this information from other than agents? 

Unfortunately - my current lot for my primary is 1 acre and VERY sloped, and close to a water source (creek), so the county has not even allowed me to permit my downstairs finished basement without an extremely costly renovation to our septic (over $60,000, and that doesn't count demo'ing and replacing our driveway to get to the existing tank and leachfield), and even if I could permit it, it would essentially need to be a treehouse in the redwoods due to the slope (not a bad idea though, I would actually love a livable treehouse on this lot!

Going to want to cast a wide net at first and figure out where you can best source your MTR leads from

You can write the best guide but people want information for credible sources so you might want to clarify all of that or it might be an obstacle all along.3.
