The realtor stayed downstairs, sitting on the arm of our couch, while the family (one of which who had a backpack) walked around our house alone. 

Hi allI'm closing on my first property today a 3-family unit.

We don't want to sell its been in family for generations. 

Having one large 100+ unitsOr5 or 6 10-20 unit multi family?

I'm aware of a couple off-market deals that I've dug up for other investors, and I know a local investor that owns over a hundred of units that he'd consider selling, all the way from bare land, to single families, to multi-units including several apartment buildings.

I personally want to use this strategy to lock in a lower interest rate on a rental property (being 20 years old with a small amount of credit history). 

Could be SFHs or small multi family.

If you can house hack and there are available two-families in your area, this is a great option to start.

Luckly I do have family in realestate so once I get my license they will guide me.
