Great property, perfect setup for a duplex with separate driveways, entrances, back patios w/ storage, brand new roof, plumbing, newer HVAC, appliances, flooring, etc.

I'm in the messy middle as a residential agent who works mostly with investors and specializes in the small MF space.  

If you don't have a full basement, the bedrooms may have floor joists over a crawl space, and frost in the winter is lifting that section of the foundation - sloping the floor.

You have lots of other choices in the free and paid space. 

When you're responsible for customizing the layout you can get more creative and find extra space a builder missed out on because they wanted to include some type of flex space or amenity room or it just didn't fit their box.

Your zoning should be ok, but you want to do everything by the book (which can be costly) to percent future insurance claims or injury claims in an unpermitted basement living space. 

After 8 years as a director in the kitchen and bath retail space, I'm bringing my positive energy and relationship building to a wholesaling firm covering Los Angeles and San Diego counties (we specialize in single family homes priced between $400-$1.7M).

Adding rooms does create the potential for more conflict but carefully thought-out floorplans, designate wet and dry storage spaces, and provide supplies.

I live on the top floor but have also rented out both floors previously via STR.

The property in question has commercial space on the ground floor with two, 2 bed/1 bath units above.
