It has been suggested to us that if we are lifting a house and moving it on the block to give a larger backyard to proposed townhouses, then why not at the same time create two separate levels of living and install fire proofing between floors, and anything else required within Brisbane City Council to allow us to rent top and bottom separately. Before I even research with local agents whether this will limit our pool of tenants I thought I'd ask here if anybody has done this. I always think I'd hate to rent the top half of a house with another family or couple in the bottom half. It just doesn't feel right (to me). If they want a unit, wouldn't they rent a unit? Properly separated, legally done, I'm wondering who would rent the "upstairs" or "downstairs" of an old well renovated house over the same sized townhouse or unit? This is suburbia, Coorparoo. I don't want to let my prejudices against such a living style to stop us making a better choice than just making one large two level house. We would get more rent from two levels, but are we thinning our rental pool too much?
