I would set up calls and then sit in and listen, every day, typically a few times a day for around 6 months.

There are more buyers for SF homes, but Multifamily properties typically cash flow better as you mentioned. 

if so does anyone know how much is the typically LTV you can takeout?   

. - Production: Typically STR production on the Oregon Coast is +/- 10% of valuation.

Without accounting for management fees (I have not yet decided if I will try to self manage), and with planning to raise rents to typical market of $825 for each of the smaller units, and $1200 for the larger unit, does this seem like a worthy first investment? 

Also, if you buy using a hard money lender or cash, Zach Starnes can do re-fi's off the appraised value shorter than the typical 6mos and then you might not need any money down if you buy at the right price.

I wanted your typical 3 bedroom house (not necessarily 2 bath) which cash flows.

I typically don’t read a post that long but yours kept my attention. :-)

We all use private investors or NON/QM investors for DSCR but some again charge points and some do not because they UW the file (Mini-C).Most Bankers typically offer rate closer to PAR or less margin built into the rate.

This is not uncommon and actual more typical as it is based on sales price and even though the first appraisal was $130k the new one gets reset based on its recent sale and home prices are not up 10% over a few months.You are going to have a hard time getting a lender to use other comps compared to this home as it recently sold.
