Corporate leases typically provide stable, longer-term tenants, while Airbnb can yield higher nightly rates but may involve more management and turnover.

So while I can't claim to speak for every financial institution out there, it's a very broad survey, finding an option not contained there might involve making quite a few phone calls.When I see 30 year fixed, 30 year amortization, 30 year maturity (basically, identical terms to a consumer-friendly kid-gloves home loan), which does in fact pop up if I specifically search for it, it's almost always at a rather high interest rate, and the borrower doesn't opt for it.

I'm working for a broker and real estate agent (as a contract handyman I'm not on their payroll)  who have recently become involved with rentals. 

It's the substance of the transaction, not the structure.So, the inquiry becomes not whether you are representing others and engaging in 6 defined activities but simply whether you do 2 or more deals involving real estate in 12 months. 

My wife is fully involved in our business.

You can express your willingness to offer a new lease to the more responsible tenant, but it's important to avoid getting involved in their personal issues.

Which is why I avoid involving an LLC on my property until all the dust settles. 

My role involves raising capital and collaborating with investors interested in leveraging my business to facilitate their acquisitions.

And in all of those, there was no bank involved in a single one. 

Given their request for an addendum, it's important to communicate clearly with them without getting involved in their personal disputes.
