It would take many lifetimes to exhaust those REI opps available and on all levels.

I have seen a few parks  empty halfway during the summer time "I am a mailman" That being said there is a market for these homes but the lot rent is going to add up quickly unless you can sell fast and buy at a low cost.

I did some investigation and it seems like a pretty good cash flow scenario with low overhead.  

Anything one can do to get a more targeted list when low on funds is a smart play if the time investment isn't too great per property.

They typically have very deep pockets, are looking to park cash, and have a very long time horizon, like 20+ years...Personally, I am interested in deals locally, but am timing acquisitions, with these expectations in mind (low to zero short term yield expectation, very long-term investment horizon).

I know a lot of agents, but I have found that it seems to be hard to find an agent who is investor friendly, some tell me I am offering too low and I don't hear back from them, but I offer those prices because that's the price I need it at to make our profit.

I found BiggerPockets from reading "The Book on Investing In Real Estate with No (and Low) Money Down: Real Life Strategies for Investing in Real Estate Using Other People's Money".

All of my credit now is low balances, and on time payments.

There minimum investment is $10k (and they will consider going as low as $5k).  

I'd probably get a good cash profit out of it, even if I sold it at the low end.
