Austin: Building Granny/ADU Unit for short term cash flow?

[Kristal Pecherski]

Hello, my husband and I are looking to build a back unit for some extra cash flow. We are new to investing. We only own our primary property and hoping to expand. Currently have our eyes on a Kanga System since it seems they have the whole package in terms of city code knowledge, and pre fab units. However, for a studio unit with bathroom and kitchenette, under 200 sq. we are looking at 56k. Expensive, no? We are in the Ridgetop 78751 area. Any advise on if we should use a loan or what to save and pay cash? Builders, codes, just general experience?

Thank you,
