It's a lot of warning signs.

We are a group of Latin American investors who are experiencing economic losses due to the irresponsibility of ABC Capital.We have found on the public page www.courtlistener.com two actions where our office of trust in real estate investments and property manager, to whom we entrust our investment and assets, are sued.We put at your disposal both actions; with the warning that they should not prejudge, since it will be the court that hears the case who passes sentence, since it is the one that knows the evidence presented.https://www.courtlistener.com/?

Fair warning.

I would start simply by issuing the tenant a written lease violation warning for denying access to evaluate any potential issue.

I would warn to be wary of choosing the lowest monthly rate, that is often a huge trap. 

I finally had to have our attorney send him a letter warning against his attempt to “activate” hiss passive ownership interest.  

Any suggestions, warnings, or references of service providers would be great!

That loan will have some bank hand-holding that people dislike (annual reporting requirements for the first few years, all rent checks must get deposited into an account at that specific bank so they can see it coming in and have an automatic "early warning signal" if they drop off, etc), but hey in their case I'd say it wasn't unwarranted, their only track record is that of mismanaging after all. 

Be wary, each fund has risks (some are "levered debt funds", some lend in second position or at higher LTV than you will like, some may lend in regions that make it difficult to foreclose, some may charge high fees or offer low returns). 2) To ask them if they have any notes for sale - Be warned, lenders may try to offload the loans that they don't want to keep on their balance sheets.

You have to be ready to chip in a lot more money at any time with no advance warning.
