You can get 30 yr fixed in residential mortgages and like @Scott England said, those need to be closed in the name of an individual....or a Trust with an individual as the beneficiary.

Groundfloor - https://www.groundfloor.us/ -Of the real estate offerings open to non-accredited investors, Groundfloor is the most similar to the Reg D platforms, by offering debt investments in individual properties.

The property has 6 individual apartment homes on one lot. 

Landlords prefer to choose their tenants, not have their renters choose their tenants for them.

And thirdly, why would the buyer prefer one over the other, if their repayments and term length are exactly the same?

I want to have the 3 m2m tenants sign new leases with me because a) I'm going to use the BP leases which I feel more comfortable with, and b) I would prefer to have everyone in a 6 month lease so that I don't have to deal with people moving out in the winter and trying to find new tenants then... 

People also use them when they want to fund a big project, but need to gather funds from other individuals/sources and hold them in escrow until enough has been collected to move forward.

They also have a preferred list of handymen and contacts, something that I didn't have starting out.  

@Ali Boone Cheers - not sure of my budget just yet; I'm used to having done traditional lending through banks and don't have much experience cash-out refinancing yet, but currently reading up on all that stuff and exploring options.I'm actually from Charlotte originally so I would feel a little more comfortable investing in the city....I think for OOS I would prefer something more turnkey at first unless I was very confident that I had good contacts (contractor) "on the ground."
