Niles, if buying a SFR (single family detached residence) as an investment, you can secure mortgage financing with residential lending terms. This said, mortgage financing with residential lending terms will require closing in your individual name(s) rather than a Corp, LLC or etc. This also applies to multi-unit property (up to 4 units).
A property that is more than 4 units will require commercial mortgage financing. In this scenario, financing can allow for application, closing and titling under a Corp, LLC or etc. Similar to residential mortgage financing, commercial lenders will require some history from the Corp, LLC or etc as part of their review for loan underwriting and decision.
If you have more specific questions, you are welcome to contact me for a detailed consultation.
