How do I claim rental income for a basement apartment plus shared accommodations with 2 other people (not family) in the top 2 floors?
Can I lump them altogether or do I have to do a form for each one? It's all in the same house.
With (approx.) 1800 square feet (600 per floor), do I have 23% personal use? (100% - 33% for basement = 67% main and second story divided by 3 = 22% each)
