As long as the property grows in equity through increasing market or renovations. 

$50K gain in equity in <2 years Lessons learned?

That gives me $100 a month cash flow and probably around $100 in equity pay down per month on something that already made me a healthy profit.I think the point about taxes increasing is the one that convinced me to hold back a little in the tank.I actually did think of flipping this when I bought it, and would likely do so if I thought I could get $128k.

Last idea, is we take a Heloc out on our home, which we could pull $40-50k out in equity. 

I believe ARV there would be about $120,000 in equity.

You have $75k in equity (based on your ARV number). 

That would leave an option to utilize $26,000.00 in equity based off of the $238K loan.That's not a huge chunk of change but if you can also lower the rate there may be a tangible benefit on top of the cash out.

I have about $100,000 in equity in it.

Still renting out, house has gained over $50k in equity and will only go up!

My duplex has gained about $50K in equity and I'm wondering if I should use that equity towards purchasing another property?
