You were not qualified at that price point (yet) and he had no right to assert you were.  

A homeowner has been in foreclosure for a couple years and has filed motions against the mortgage holder, its counsel and mortgage advisors asserting that they did not have legal authority to schedule a sale, that they failed to obtain proper, legal valid assignment of mortgage and power of sale, that the foreclosing party is in violation of Federal money laundering and wire fraud statutes, that there were violations in Truth in Lending, that he filed for bankruptcy, that he had a binding arbitration underway, etc. etc.  

Well it all depends on your investment strategy, but I would definitely disagree with the assertion that you made a bad investment. 

HiI know we don't take mortgage payment in operating expenses when calculating NOI or Cap rate, however what if the down payment is done by refinancing your another assert?

Your assertion on the Garn St Germain Act is correct.However, although no trustee is required to be named, users of anonymity trusts should anticipate objections from a future title company based on the proposition that a trust is not a legal entity—which it technically is not, even though trusts often act as if they are in fact legal entities.

Anything official in a lease agreement, or even a handshake assertion that "your last month is free if you use my gal" would be a straight up inducement, and in states with tight anti-inducement laws straight up illegal.Otherwise, induce away! 

There would be a gift tax return filing requirement, even with no tax due.Such a transaction could jeopardize the previously executed  1031 exchange, as the IRS might assert that the property was never held for investment, but rather with the intent of gifting away to a child.

The IRS has challenged similar arrangements in the past by asserting that a replacement property in a 1031 exchange that was either (a) subsequently gifted to a child or (b) rented to a child did not qualify as exchange property because it was not "held for investment." 

Always be calm but assertive. 

I am capable of making well over $100,000/year if I assert my time.
