LLC for 9 plex, will it affect DTI

[Hannah Forman]

Hello, I am a real estate rookie. I am hoping to seller finance a 9-plex from a family member, but I am trying to figure out the logistics. I want to keep it very professional, and set myself up for success as a business. I understand as soon as you get greater than 4 doors its considered commercial, but not sure how seller financing comes into play with this. 

My question is, if my husband and I create an LLC, and do the seller financing through the LLC and a business bank account, will this affect our personal DTI? We are also hoping to buy a personal SFH through a conventional loan, but not sure how our DTI will be affected by the 9-plex.

Any help is much appreciated! This is all new, and I've been reading the RE Rookie book suggested on here as well as listening to podcasts. 

Also, if you have an attorney or someone professional I should talk to about this, I would appreciate recommendations!
