I'm tying to be very careful before I request any more loans. 

Do you have a relationship with a local lender that would be more willing to work with you now & in the future vs. a larger institution to whom you're just a number and they don't really care about at all.

BUT I also want to emphasize that it should be done carefully with a well thought out plan, and hopefully a plan with multiple exit strategies.  

Or should we merely roll all the assets under our current LLC structure (note: our state doesn't care about DBA- you can have 30 companies with the same DBA so long as there are no complaints/TM infringements).Many thanks in advance- and to answer a few questions; no I won't share the name and would appreciate it if others wouldn't as well. 

Just be careful and run your numbers with an extra padding if you invest in IL.

They don't care if they make any money on it but they don't want to lose money either.

Be careful what Gurus you listen too.

Some lenders may not care or may have more generous guidelines. 

Careful who you listen to and understand what they are saying.

Just leave it under the house..instead of using the very costly Trane unit I would use the cheapest no name brand..if it blows up in 8 years who cares?
