Solo LLC question for new investor

[Kathy Moser]

Hi Amazing Investors!  

I am in the process of negotiating an installment sale contract for 3 houses, one of which will be my primary residence.  The houses are not currently mortgagable but those issues are resolvable over time.   The owner wants to sell soon so we are starting the deal with seller financing.  

I want to form an LLC for the 2 investment properties so that I can buy the primary residence with a conventional loan without the investment properties affecting my credit score or DTI ratio. If I do a solo LLC it will appear on my 1040 and it is considered a "disregarded entity" in my state. I could do an S corporation instead or have the LLC considered as an S corp.

Any experience with issue would be greatly appreciated.  Thanks!
