And, if the money is borrowed and you lie on your loan application about that (they will explicitly ask and you will have to explicitly lie if you want the loan) then you're committing loan fraud.If you have to turn right around and sell this property for some reason, I,as the lender of the 20% down, will suffer a 50% loss. 

We called lawyers but they said the company was so big that they were highly invested in top lawyers that would drag it out for so long the recovery would be a loss.

To give you some perspective on what those tax increases can look like here are some examples of the changes based on some of my properties that I own in the city:$4096 -> $5522 (+1426)$3850 -> $5516 (+1666)$3835 -> $6283 (+2448)These are only some examples, but all of the properties that I own have increased in its tax assessed value, therefore drastically increasing the taxes per year and decreasing annual cash flow.While tax assessments are normal it seems that this is a very drastic effort to recuperate losses.

So, this created a few issues along the way and ultimately a loss of potential profit.

Job loss, divorce, severe illness, Covid impacts, etc.
