Here are some considerations for investing in a duplex in the Dallas area and potential alternatives:Investing in a Duplex:If you rent out one property, you can possibly create positive cash flow by partially offsetting your living expenditures.If you're an investor with limited funds, duplexes could be a more accessible alternative because they may have lower entry expenses than bigger multifamily properties.Perform in-depth market research in the Dallas region to pinpoint communities that have high demand for rentals and good prospect for real estate growth.Take a look at owner-occupant-friendly financing choices including FHA loans, which frequently have less down payments.Make sure you have a well-defined escape plan.
