Bigger pockets has rules against posting links to competitors websites please message me and I will send you a list of meet ups. 

Bandit signs do the same thing and are time tested however they’re only up for a few days before being ripped out of the ground by competitors.

Another option is Zillow Rental Manager; however, if I owned that many units I'd likely be using AppFolio or Buildium or one of their competitors.

They dwarf the nearest competitor and the Blackstone name is them advantages some other funds can only dream about (including the top puck of managers and cheaper financing).

And you're right I find it funny how we all could view one another as "competition" but one thing I learned early is that every connection in real estate is not a competitor but a potential partner or future opportunity. 

I have no interest in buying second hand information that is being sold to a hundred of  my competitors.

I would recommend seeing what the nearby MHP parks are renting for (hopefully your park is below market rents) and see if those competitor parks are billing back for utilities. 

But if things are indeed as bad as they say they are, it creates an awesome opportunity to normal investors that are able to provide a level of service and a higher quality product that will be able to easily compete with a larger, more clumsy, competitor - especially after their issues are brought to light with increased publicity. 

Some competitors may be flagging them.

Unless the business has readily salable easily repossessed assets that are valued for quick sale in excess of the loan amount, and those assets have not been pledged via a UCC filing to trade accounts or other liabilities, you're banking on the continuity and profitability of the business itself.Small businesses are notoriously difficult to evaluate since the quality of their accounting varies widely; the key personnel play such a key role; their market position can be devastated by the emergence of a key competitor, the loss of a key account, or the exodus of a key employee.That is why companies that buy receivables from small businesses target returns of 36% plus, and often the risk is so great they layoff some of the risk by partnering.
