Or are LPs more concerned about the technicals vs the warm and fuzzies?  

The lack of short term rental data available to the appraiser concerns me. 

Two of the biggest challenges I face are that I’m not very liquid at the moment, and the Seattle area is extremely expensive.

This added inventory gave renters more options, leading to increased competition for landlords.Why This Matters (and Why There's Hope)For landlords accustomed to a manageable 6-day increase in DOM during the holidays, the 10+ day spike might feel concerning.

This led me to have an extreme ambition of trying to give my future family the things I didn't get.

And if you base an offer price on that, you'll likely have an extremely difficult time getting any traction. 

Your wanting to do high-risk via extreme leverage....via high risk OOS investing, committed to never being boots-on....... via high risk class c....... doing reno's to make habitable which is high risk at a level we should just call it EPIC risk..... 

It sounds like they have been paying, maybe talking to them about your concerns can help them better meet your expectations.

This is due to the extremely annoying TX 50a6 home equity laws.

However, a lot of concerns can be mitigated with looking at their past rental behavior in a lot of different settings.
