I also got married and had my first child during that time, so we bought a new house and kept this one as a rental.In late 2015 I found BiggerPockets while searching YouTube videos on real estate investing. 

My fiancé and I are getting married in 2 years but plan on getting the house this year.

If the house you are selling is a primary residence, then you will be covered on capital gains up to $250,000 single and $500,000 married.

She got married and I'm guessing her wife has a child also because I'm being requested to provide a letter stating that the two children live there.

Great option if you're bachelor, maybe not if you're married!

I'm not a tax expert, but I seem to recall that if your move was over 50 miles away and was due to a military reassignment, you may be eligible for a partial exclusion ... so not the full $250k (or $500k if you are married) but darn close to it since you were close to the 2 year mark, and probably enough to wipe out your tax bill entirely.

You can ask them for examples ... what are you good at ... listen to what they are doing, what they need, know what you are good at and marry up the two to add value ... figure out how to do that on a consistent basis with other investors, sellers, buyers, and really everyone you meet and the world is your oyster ... and that is true in REI but goes well beyond.

My girlfriend and I plan to get married and live in her home state of Rhode Island.

Don't marry the guy until you date him first.

I'd like to update my last name with my married name but I can't seem to figure out how to do it.
