I'm not familiar with how European real estate transactions work but personally know I would feel a lot better if there was a third party involved holding the money

Going full bore on them will hurt their feelings and may cause them to move.2) Do NOT get involved in disagreements between tenants unless they are willing to file a police report or one of them violates their lease!

If you have another professional advisor (attorney, CFP, etc) who is involved in advising your business, they may be able to provide a similar letter. 

I'm also looking to connect career-wise as I am making transitions in my life right now & want to restart my Real Estate Journey or some type of involvement. 

Realize at the outset that real estate will involve all different types to service, maintain, repair, improve, insure, manage and eventually sell.  

Why would you want to double down on the biggest risk involved with real estate, liquidity risk?

@Raymond Yan why are you getting involved in the eviction process?

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.
