Is one of these institutions superior for any reason? 

@Samuel Coronado, @Elan Adler  Entire subdivisions of build to rent put more pressure on local landlords because the big institutional investors can afford to buy tenants with low rents and free initial rent period.

Deposits from the tenant.Security deposits from the tenant in residential dwelling units shall be deposited in a trust account with a licensed and federally insured depository institution lawfully doing business in this State or the landlord may, at his option, furnish a bond from an insurance company licensed to do business in North Carolina.

I would be amazed, shocked even, if a traditional financial institution was willing to lend on a non-habitable asset up to 80%. 

She took about two months studying outreach particular niche and instituted a program in steps where the results could be verified before implementing the next step.  

If she's still there, institute your holdover policy. 

Are there banks or financial institutions that would grant a loan at less than 25% down, say 10% for someone with exceptional credit? 

Or a DST which absorbs all your debt but still leaves you with some cash flow because of the institutional financing already on the DST property.  

I will say that communication with OpenDoor is much better than that of other institutional sellers I've worked with.

In the end, it is up to how the investor themselves classify the lender.HML is thought of being more "institutional money".
