However, it is SUPER common to do so.

Also, you are offering way too much, not sold for a year, ok it has issues. 

Common lead source or so called (all in one AI powered software) for me are a big scam.

Private Placement Memorandum (PPM), Subscription Agreement (SA), and Operating Agreement (OA)These are the three most common "docs" for a syndication.

Hey BP, I have seen some people have been asked to give a down payment just to apply for a loan (in the last conversation I had , it was with an investor who needed a commercial loan) How common is this and why is that even asked before the loan has been given, would it apply to the balance eventually? 

Go on youtube and look for Seeing eye dogs training and you'll get an idea of the type of vests that they wear as well as how they behave compared to a common pet.

Not quite the same issue.

There are lockable thermostats for commercial use, but I can't see that working in a rental.I think the main issue will always be that any thermostat that you can set a minimum temperature in will always be susceptible to this fail safe failing, due to the possibility the tenant could change it on purpose or on accident.I'd hope in a 4 plex as long as there is no building defect to the thermal envelope that it would be difficult for one units pipes to freeze as long as the other units were occupied, seeing as they share some common walls/ceilings.

Somehow, it seemed to blow up as an issue during Covid. 

It's a turn key, good flip with a few minor issues.
