Take a look at current interest rate trends and forecasts.

I'm currently renting it to a family member under the agreement that he moves out in time for us to sell it within the 5 year window so my husband and I will have lived in it as a primary residence for 2 of the last 5 years (we moved up to WA a year and a half ago).

Currently, I own one rental property. 

Currently looking at a ~$1.35MM duplex in the Los Feliz / Silverlake area.

I’m currently in the market for a second long term rental property. 

Ok, so does that mean never had one before or don’t have one currently?

I currently rent out 3 of the 4 rooms (all MTRs) and keep 1 for myself.

For me to build an ADU in central California at my current house would cost only about $80k and would rent for $1500/month which is almost 2% rule.

. ;)   Not raising the rents to market is just subsidizing someone else's lifestyle at the expense of your own household.
