Then had $80000 in equity year 2017.

A year later that same home is now worth 150k and I have since put 10k into the principle on the loan.Would I now have 80k in equity?

In 3 years, I have about 70k in equity in my townhouse and about 100k in equity in my SFR, all from appreciation in this crazy salt lake city market.

I built it myself and have about 85,000 in equity in the home. 

Some people think that because they have paid on a 30 year mortgage for a few years that they now have lots of paid in equity, and will be disappointed to discover there is less of a maximum draw amount available than they had hoped for.

I have 24 year loan and have roughly 25k maybe more in equity.

I don't have any real estate investing experience but I just jumped into my first RE deal by taking an option on a pre-foreclosure where I expect to capture about 40k in equity after expenses.    

Since this is an FHA loan that was originated over 5 years ago the MI will fall off after 11 years or when you reach 20% in equity.  

You're losing money and you don't have to, and that area is absolutely awful for appreciation so you can't make it up in the long run in equity gain either. 

Person A lived in their home 15 years and has $50k in equity, Person B lived in their home 5 years has $16k in equity.
