Hi @Adam Pervez! You honestly have great cash flow with your current investment. The answer to your question, in my personal opinion, is to do exactly what you're looking to do in the future, right now...invest in small multi-family (up to 4 units) that you can purchase below market value in developing areas in order to capitalize on the appreciating value...but to do it with properties that also have lower entry costs, strong rental demand, positive cash flow, and with lower property taxes. Not only will you continue to build your portfolio, but it can offer the tax benefits to offset your high income.
Out of state investing can be very beneficial for someone in your shoes. But, I'd recommend going the B2R route where management is already in place for a turn-key process without the headache of dealing with tenants and property issues for, at least, the next 10 years. We're in several Florida markets for this exact reason.
I am working with a 20-year, veteran, cash investor right now that is navigating this exact problem. His profitability with the current properties has capped & he wants to get out before things hit the downturn. This is the same conversation I had with him. Happy to answer any questions.
Feel free to connect with! (Same for you @Joseph Chacko vellukunnel.) Good luck!
