There are are other reasons, but those are the biggies.Like Zachary said, keep it simple.

Even if you take a loss on your investment by getting out, it's probably better to part on good terms than having to lawyer-up.  

With long term rental, we coulnt cover mortgage at all, with short term rental, there was possibility to cover mortgage ans sometimes it did. 

Other options include regular loans with a 20% down payment or getting a long-term roommate.

If the owner was responsible for the booking, and you are simply taking care of people as they are there (you mentioned that it is a BnB), AND your contract does not state any terms for canceling they probably can do whatever they want. 

First off, I would lose the term "elderly" and refer to it as seniors, senior living, etc. 

My focus as an investor is buy & hold real estate with long term and short term rentals.In 2022, I am looking to network and surround myself with others in the industry to ultimately help each other expand our real estate businesses. 

I thought it was their job to look everywhere to find the best rate and terms.

I’d love to hear who you’ve used in similar situations, or what sort of rates and terms could be expected.

Depending on the property type and terms this can be justifiable but usually reserved for those with ample experience and higher risk tolerance. - Higher and Hard Deposits.
