Ramon,I am a client of Truth In Equity. 

Then, products such as HELOC or 1031 exchange are not open to me as a foreigner so even though i have on paper $500k in equity I don't have a real way of tapping into it.Any ideas or suggestions what I can do now to keep growing would be much appreciated!

Runaway inflation could have dire effects, certainly.You want to be in equity, whether that be property, precious metals or some other resource.My $0.02 ...

As of now, our rental company has over 300k in equity and no debt.

To pull equity out, you have to leave 25% equity in the property… so on a $100,000 house with $25k in equity there is ZERO money you could take out of it, because the first 25% has to stay in the property.  

William,Can you give me some numbers as to how many dollars in equity you would pull out of the 1st house and how much your second purchase would be?

We have about 80-90k in equity in our residence and another 60k in IRA's/Roth.

Our credit scores are both above 750 and we have around $50k in equity with the house.

What I mean by this is buying a property that offers enough room in equity, cash flow, etc. to the point that you can still be positioned correctly regardless of market fluctuations.

You have $100,000 in equity in the property costing you $833/month in lost income, you do not want to lose any more.
