I will mostly likely reside northern Seattle/Snohomish area, which is determined by my job placement somewhere in the manufacturing industry of Washington.

I own one rental house that was our former primary residence.

You never once notified the resident that there was a sale going on.

I used them on 3 loans (even my primary residence).

Primary residence (in Nevada).

I might not be brave enough to try that for a flip, but I would love to do that for my personal residence.

Not sure if this transaction would qualify for a 1031:http://www.1031corp.com/1031-exchanges-made-easy/1031-exchange-requirement/Originally posted by above link: ...Examples of non-like-kind real property that cannot be exchanged under Section 1031 include primary residences, “flips,” stocks, bonds, notes, mortgages, cash, equipment, goodwill, inventory and interests in a partnership.Emphasis (bold) is by me.

If you don't ask, the answer is "No".It is unclear if you meant you want a HELOC on your primary residence or the subject property or some other property.

The terms of the tax credit required that I live in the house as my primary residence for a period of 3 years.

In trying to figure out what loan is covered by what law, people will ask, "is it a one to four family residence?"
