The majority of "residential" lenders will sell their loans to Fannie Mae or Freddie Mac. Those two will not buy more than 10 loans per individual. So you are capped out. Now some local banks may "Portfolio" loans (meaning they keep them in house).
Commercial loans are backed by private funds, groups, VCs or kept on the books by larger institutions even smaller ones. This means they do not have to play by the Freddie and Fannie rules.
With that being said, if you have a loan in your personal name, it is recorded against the deed/title. This means, if you get a loan in your personal name, even if you the title is in a trust, or LLC, you are now going to named in any lawsuit should a tenant, their friends, etc get hurt etc. on the property.
You should also have insurance, but a properly filed, kept and operated LLC will add to that level of liability protection.
Did that accurately explain it @Martin Zawarski ?
In other words, I will say this yet again. This is a BUSINESS. Treat it as such. Do not endanger your personal assets, and file your entity as you would if you were to start a restaurant, an auto shop, a car dealer, etc.
Stop treating REI as a hobby. Deal with BUSINESS Bankers, as you are a Business person.
