You can avoid property tax by selling it and using a 1031 Exchange. The "2-in-5-Year Rule" doesn't matter.
I would recommend you sell. If you only make $200 a month after paying the mortgage and property management, then you are technically in a negative cashflow. You should be setting aside 10% each month for maintenance, 10% for capex, and 10% for vacancy until you have a healthy reserve established.
You also have to consider Oregon is increasingly unfair to Landlords and that is unlikely to get better. You should move your capital to a state that is more tax friendly, believes in justice for Landlords, and where your money can cashflow better.
once you collect the 10% for each of the 3, what is consider a healthy reserve? The point to where okay I can now stop saving this 10% for this category.
Curious
capex healthy reserve = cost of at least one of the most expensive repair (example roof replacement)
vacancy healthy reserve = is 3 months worth of your property bank mortgage payment. (thats what im doing)
maintenance healthy reserve = I would stop saving for this area per property once I have 12 months worth of it?
