How to handle this

Good day everyone. I am fairly new to REI and I have a ? regarding the use of using a HML on this deal. I have the oppurtunity to get 2 tri-plexes, fully rented ($400 per unit rent) for 50-55k (asking 64k for both). My comps per buildings are 45-59k. Appraisals are 102k for both. Then there is a school building and land (about 3 acres) that I can get for 55k that I would like to convert to be my primary residence. This property appraises at 92k (as-is). Now if I were to get a HML for these properties, would they have to separated because of investment purposes, because of the school becoming my home? Also it is now zoned commercial, will it be hard to get it zoned residential? Any advice on how I should handle this will be greatly appreciated. Thanks any and all.
