And I also wasn’t sure if it was a good idea to transfer the house into the LLC also once it was formed.

If you are setting aside funds for capex, taxes, insurance, or other expenses that don't occur monthly, transfer those funds to Savings each month and hold them there until it's time to spend them.

The mortgage & re industry does not want to see seller finances and the banks don't want to see their loans that they underwrote transferred.

Now he is saying that it's a "second home" mortgage (higher interest rate) because she won't be living there (but if I buy in MD, we still have to pay the state transfer tax because I have owned in MD before.)

Do I create an LLC to own the property and use a quit claim deed to transfer ownership?

@Jacob PalmerTaking over tenants in a duplex means you must honor lease agreements, transfer security deposits, and provide proper notice.

Yes I didn’t transfer the service right over to my name, and I’m realizing this is one of my biggest down falls.

The security deposit should also be transferred to you as part of the closing.

It's hard to ignore the benefit that any tax saved is basically a wealth transfer gift to the beneficiaries. 

.- Flexible transactions make it easier to sell, transfer, or refinance individual properties.Considerations- State variations mean that not all states recognize Series LLCs.- Management complexity necessitates careful documentation and legal compliance.- Lender familiarity issues arise as some lenders may not understand Series LLCs, thereby complicating financing.A Series LLC offers a streamlined, protective, and flexible way to manage multiple real estate investments.Thanks,
