Great insight and advise.

My broker advised me to "bite the bullet" and close the deal, telling me that I should be glad I wasn’t losing money on the deal.

Yes you also get appreciation, but when a total stock market index like  (IVV) returns 30% over the last year and 90% over the last 5, I have a hard time advising someone to buy a property for all cash to receive 5.3% along with the risk, property mgmt etc.  

Readers are advised to seek professional advice.

I would list the property and advise the tenants you are planning to sell. if they want to stay month to month, that's fine.

Geesh.The Broker also who wrote those contracts and advised their clients to make these deposits most certainly has some liability here. 

One the ice maker is not advisable.

Regarding the Zelle versus Avail issue, I would advise choosing your battles wisely - as with many aspects of life.

I wouldn't advise pulling a HELOC unless your numbers are dialed in and you are willing to take that risk.
