Feel your pain.

I've attached one link.From a lender's perspective, it's much more of a pain to do the parent and then children LLC's because we need the entity documents for all of themmost lenders require the LLC to be specific to their transactionyou'll need to keep the funds separated and many times, the LLC doesn't have the assets for reservesthe filing fees for each entity can become onerous and if the property is in a different state, you'll need to provide the foreign entity registration as well as the certificate of good standing in each state   Instead of setting up all of these different LLC's etc..., until you get to a point where you can no longer use Fannie Mae and Freddie Mac financing, get a good umbrella liability policy so you can enjoy the more favorable financing.https://www.biggerpockets.com/renewsblog/the-tradi...
