I use iGMS to manage my STRs and really like them. 

Deep value add multifamily project. 4 units. 2 x 2 bd 1 bth, 2 x 1 bd 1 bth.

Does anyone have a system they use to filter through the endless available markets and narrow down your options to something a bit more manageable?

I contacted a Matt Robertson (Sales & Operations Manager CiX) and he acted as if this was the first time ever hearing of this and that he was all in, in helping me get to the bottom of this. 

Lastly, find a property manager that matches what's most important to you.

I am self-managing my ADU build in Oakland, CA and have come across a few snags. 

Given this I know I will need a property managner/property management firm at some point.

If I'm trying to determine how much to rent an LTR for I'll also use Zillow to see what others are asking for similar homes and how many people have reached out & applied.If I'm trying to determine how much to rent an STR for I'll use the enemy method, AirDNA, and estimates from property management companies.

Although no major renovations were needed, our strategic approach and rapid transaction management significantly increased the property's market value.

Self manage?
