I don't number my properties (I don't own anything anymore I don't want to keep) but I do keep tabs on my net profit independent of income taxes on each unit because if a unit starts to slip I need to know if it can be salvaged (have I been consistent with rent increases?

I like both of your ideas so I would look for the single where an ADU is permitted or one with a dump ADU to renovate (that's best) and balance that against the purchase of a 2-4 unit.

Trying to figure out whether is it worth transitioning my 2br 1ba 1100 sqft unit to midterm rental from long term rental in Renton WA?

I’m on the verge of firing my property manager due to 7 months this year of at least one unit being vacant.

Did a 125k upgrade to unit, but now need to make income.  

I considered adding a universal gym but will go with billiards and foosball instead.There are more spas in this STR market than EV chargers ((only 5 or 6 units have a EV charger), yet it is about 200 miles from the nearest large metro (too far for most EV to go without a recharge).  

If the rent payment covers your mortgage and you have a good tenant, why would you get rid of them to take on the expense of unit turnover, because you will have to do one, and the 5% vacancy loss just to increase your rent $150 per month?

Those two units make a good combo.  

My lease requires renter's insurance which should cover loss of use if the unit becomes damaged/uninhabitable, but I don't think renters insurance covers costs of living expenses incurred during just an evacuation.

If you are buying another home, I think there are also ways to transfer your mortgage.We have mortgages that are similar to that in the United States but use different terms to describe them.
