A couple of things I like to tell my newbies-Owning a short-term rental property can offer significant financial benefits.

@Helena Goyvaerts it will be tough without 2+ years of USA tax returns showing you are profitable.Higher interest rates have negatively affected most lenders and many of them are getting more aggressive with offering more flexible programs. 

Not a lot of our competitors offer this but it's something we can consider (but for us, it can't be in a rural area, the loan amount must exceed $150k, if we're using PadSplit income (or STR/MTR income) the max LTV is 75% and the down payment must come from your own funds). 

Is any bank offering a HELOC based on the combined equity?

I’m a new investor based in WA state with an exciting opportunity to relocate for work in the U.S. and out of the 92 cities available, I’ve narrowed it down to 13.

National banks typically do not offer products that suite your needs here. 2.

I offer an online payment portal to submit rent payments via ACH or CC - they "couldn't figure out how to use it" so I set us up to accept Zelle payments.

I believe it's because the property is being sold "as-is," and they are unwilling to make repairs or negotiate based on findings.

Did you use standard offer contract for your jurisdiction? 

Class C properties are considered the riskiest investment, but they can offer good cash-on-cash returns.
