if for LLC, mortgage will be commercial -- how higher the interest rate than residential rate, for a 4 family?

The conventional loan limit, Fannie Mae/Freddie mac is 10 mortgages properties, after that you’ll need an in house portfolio loan or commercial loan.  

I have 2 properties currently financed with a private lender, wanting to refinance with a bank commercial loan for longer term.

The reason I ask is that I work on a lot of large commercial projects(read projects in the hundreds of millions of dollars) and even those mega high paid architects and engineers miss things in their design.

CoStar is a good source for most research pertaining to Commercial Real Estate.

Lots of questionsWhat kind of property (single family, multi family, commercial)Borrower's credit scoreIncome or no income verificationOwner occupied or non owner occupiedcash out or rate and term Lots moreLoans are like Plinko on the Price is Right. 

Become a property manager, real estate agent (commercial), appraiser, inspector, mortgage broker, etc.

I am a national NNN commercial broker & syndicator and love the STNL net lease & MTNL retail shopping center space.   

Anyone can comment on how to split electrical bills for a shared space?  Specifically, 2 office studios on one meter.  My concern is what do you know when one tenant uses more than the other?  How do I prevent arguments?

Some of it seems more geared towards commercial real estate and very large residential properties but I’m liking what I’m learning.
