I'm newly married, so now with a dual income household and split expenses, I'm starting to feel more comfortable about taking a step into investing in real estate.My original goal was to always keep my current home and rent it out regardless of where I moved next, because I think we could make $200-300 per/mo. on it (not including maintenance/vacancy) - and when the mortgage wraps up, even better.We're not looking to move any time soon, so I think our next step will be to look for a duplex in 2022 - hopefully near Bay View but open to other Neighborhoods in the Milwaukee area.
