Buying home for family in Austin, can I get 2nd mort soon after?

[Bo S.]

Looking for the best strategy on two mortgages in short time period. I'm helping my parents purchase a home in Austin, the home would be in my name and would be my 1st home. Parents would make the monthly payments. But I currently live in Seattle and would also like to buy a home here. Planning on conventional loans with less than 20% down for both properties. 

What's the best way to go about this? How long would I have to wait between the two mortgages to qualify for the 2nd home in Seattle? 

Thanks in advance,

Bo
