Portfolio Loan Questions

[Peyton LaBarbera]

I have been looking into portfolio loans and I have a few questions that need clarifying

First off when you get a portfolio loan can you add additional properties after creating the original loan as in the future I am looking to keep expanding my portfolio?  If so does this affect the current rate I have?

Once a property is paid off in this style of loan can I individually sell that property or do I have to sell the entire portfolio?

Does a portfolio loan work with multi family homes of 2-4 units?

Lastly If I want to switch my current properties held in my LLC into a portfolio loan is that just a matter of switching things around or do I have to refinance all of my properties?

Thank You,
