One more hard to believe post  

What kind of tax exceeds the total income revenue made on a sale?

If the sale is a loss of revenue, isn't that a deductible amount?

I am aware that it is possible to owe more than the offer to purchase property.  Normally you would not take low offers, you could improve the value of your property, you could hold the property until market value increases, or if you really underwater you could file bankruptcy.

If taxes on the sale of property are so high that anyone can not afford to sale, then people need a new government.

Reading your post I considered it really stupid untill I read the last line "all he can do is keep taking loans against the properties" I now know for sure you are clueless!

Taking loans out on properties is a way to leverage funds, done all the time.  Banks just don't say " how much money do you need Mr. Trump".  Banks have a tedious method to verify any and all loan requirements, they do not loan money on property underwater.

Your post is just BS!
