VA Financing 2nd property

[Raymond Popsie]

My Wife and I are both Veterans. I used my VA Loan to purchase the single family home I currently live in. We are selling our house and taking the equity to invest in multi-family homes. We intend to live in a triplex or quadplex (not to much inventory here). My question is after we purchase our first multi-family home and live there for a year can we use the VA Loan again for our next property (if we live in it). For the second property will it considered an investment property and require 25% down for a conventional loan? Any help on using the VA loan strategy would be helpful. I understand the first purchase however; after that I am a bit confused on what type of mortgages are available.
