Sell it now, net gain about $40-$60K after taxes, commissions, listing price, etcTo properly and adequately answer this question, one would need to know your strategy and goals.Strategy A is based on cash flow to support living expenses.Strategy B is long term wealth building - appreciation (market and forced) combined with principle pay down, depreciation, etc.If you strategy is A, then you should sell as this will not turn out positive for several years down the road (unless you utilize some sort of house hack play, vacation rental to increase income, or any combo of increasing income and reducing operating expenses - which by the way you skipped a lot of those in your analysis so your negative monthly cash flow is actually greater than you explained.)If your strategy is B, then by all means keep it and enjoy the likely future appreciation, amortization and depreciation deductions to offset your actual loss each month until the unit goes cash flow positive.
