@Michael Ndjondo makadi the correlation between competitive price and not providing their w9 is that if they aren't providing their w9 they're not being "forced' to pay income tax, so that's a savings to them.

would that force them to leave?

As long as you are not forced to sell you will make money.

What world are we living in where the only reason a buyer is using our services is because we forced them into it?

Or I'm forced to find another provider who is willing to bill him. 

It may not be a bad thing for people starting out, because it forces you into deals with better cash flow.

But if you purchase correctly (buying below market value with an opportunity to boost value with some simple upgrades) you will quickly see the forced appreciation as well as Day 1 cashflow.

Remember you can't force a deal to happen.  

-After that refi I was thinking every 2-3 years a partner could ask to be bought out and if no one member wants to buy them out then the can forcefully sell their share of the business to the other partners.A few questions that I have for everyone here;-What amount of insurance would be appropriate for the business and should I also have an umbrella policy for myself?

For example LA is having a "come-to-Jesus" moment over the homeless issue, and parts of Chicago with the rampant crime, and on other side of that coin there is parts in TX and FL that have a unique force factor in play pressing greater than average appreciation.
