Quote from @Edgar Duarte: hi allI would love to get some perspective from your expertise, we have a property that we would have to sell in 2025 to avoid paying taxes on the capital gains, we believe we rcan sell it for $700K and get an equity of almost $500K after paying the mortgage balance, if we invest all of it option in index funds at 7% rate (standard com growth calculator), or in more rental properties as we are all here for, I can get the equity of around $900K.option B would be keep paying the house at 2.3% int rate while we have it in AirBnB and maybe sell it in 10 years for $900K, knowing that we would be paying taxes but it is not that bad still. or we can 1031 at that point?
