@Andrew Lavier You will get the best, detailed answers by going directly to the source!

HMLs are good but they aren't always the best source of help fund deals.I hope this helps answer your questions. 

I’d say the most important thing is finding the source.  

You won't figure this out from Costar or Zillow or most other data sources. 

You can search online for companies in your area that lend that way.But I'm guessing if you talked to the people around you, showed them what real estate investing can do, and offered a good enough return, you could pool money from multiple family and friend sources to make it happen.Most people aren't sitting on tens of thousands of dollars, but most people have 401ks or IRAs and if they trust you, and you are trustworthy, you can teach them how to pull loans on their retirement accounts that don't penalize them, and give you access to more money than you realize you had access to.Probably start there.

Hands down the best source of information.

Look at the source of the funds used to make each payment. 

At the root of this method is just basic math.

Banks are very familiar with mobile home parks and how to structure loans.The top sources of mobile home park lending are:1) Seller financing by the moms and pops.2) Bank loans (typically smaller banks in the town the park is located in).3) CMBS Conduit lenders (on deals where the loan is $1 million and more).4) Fannie Mae/Freddie Mac "agency" debt (on loans of $2 million and more).You rarely hear of a mobile home park deal that can't get financing today because banks love the industry and it's incredibly small default rates.

It’s a problem with your source of funds
