Alan - are you saying my friend's analogy is wrong because if I were to buy my current CA house "today" using the hypothetical $350k the property tax on my property would be almost double the current amount of $6,800 per year?
Here is our exact situation. The house would likely sell for $850k, we owe $440k. We refinanced a couple years ago changing it to a 15 year note at 3% interest. Our PITI is $4,041 per month. We could rent the house for $3,400-$3,700 per month. So it seems the only way to make this thing cash flow would be to refinance the house again to a longer note. If we had to pay our CA mortgage and an AZ mortgage at the same time we could do that. However, I'm not sure about having so much riding on one single family residence. Maybe diversify that $350k a little more (multi family, notes, etc.)
Our income is high enough that we could completely pay for another house in AZ quickly without using any money from our CA house (as long as we keep the purchase price reasonable)
