Financially, we have about 40k pooled in our fund now, and inject about 15k each year (before any gains/losses).  

If the LLC has no money to pay for the defense, you'll be injecting money into the LLC yourself to cover the legal fees, just as if you had no LLC at all. 

The likelihood that you could buy out the investors from refinance proceeds alone isn’t likely to work mathematically unless you inject a lot of your own capital.

A lot will depend on the financial condition of the banks when interest rates go up (and they will have to at some point due to all this money the Fed has injected).I had a bank call a loan on my first home in the early 1980's (which I tried to sell with a wrap).

This should inject a healthy dose to my credit score and while making the monthly payments on them at the same time.

I've looked into this and HHBR is in need of a serious cash injection and by all accounts the surrounding neighborhood needs regeneration too? 

Try and work with the seller, maybe they are willing to provide a vtb allowing you to inject as minimal equity as possible.

There are plenty of contractors out there wetting their beaks to hear your news of capital injection available.

Flipping, if done right, can give you quick injections of cash.  

For our business model, it would be too impersonal to inject this type service.
