Also, how much capital will you be able to inject into your business either through saving, side hustles (including flipping), and using other people's money?  

Nothing else works.4) Inject a "pride of ownership" into your residents with immaculate common areas and they will take the ball and run with it.5) Don't let city officials push you around -- find a good municipal lawyer and your problems are suddenly solved.6) A successful mobile home park is like a high-density subdivision in which the neighbors watch out for each other and have a strong sense of community.7) NEVER rent mobile homes -- sell them at whatever price you can get and focus STRICTLY on the land rent.8) Smart owners copy what other successful park owners are doing verbatim and bad owners try to be pioneers.9) Think like a lender and you will always be successful (my happiest moment was when I got a conduit loan on Glenhaven as that confirmed that all my steps had been correct).10) Don't listen to your friends, family and peers when you buy a mobile home park as they will all say you're nuts.

Meaning, it is a combination of the investor personal money (his equity injection) and the money he borrows.

Maybe I'm just not looking hard enough.But appreciate the help.I'm just injecting my positivity in this thread 😁

I got 3 quotes from 3 contractors all suggesting different methods. 1 - $23,000 - 47 concrete piers with rebar2 - $6,500 - 38 concrete piers with steel support beams 3 - $11,000 - no piers (more on that below), polyurethane injection Contractor 3 said piers aren't necessary as their is clear evidence that piers had already been installed previously.

That manager had a tendency to inject himself into EVERY aspect of operation. 

If that doesn't solve the issue the first thing you can try is injecting the cracks.

Our rising national debt and The Fed's massive injections of cash into our economy seem to be very strong economic indicators that are concerning when considering future taxes and inflation.

I currently have a summer job where I have saved just over $6000 where I have slowly started injecting into various etfs.

@Nathan Adams depending on the size and location of the crack you could extend downspout ends 3-4 feet away from the foundation, Install a French drain, inject epoxy into the crack, apply some tar to the foundation or maybe a combination of these.
