@Charles White Thank you for your service.
VA loan benefit is a great way to get into real estate investing. You can use your benefit for 1-4 unit property. The benefit increases as the units increase, and the benefit amount is different in different counties (to account for cost of living). For Pittsburgh (Allegheny county) the limits are:
1 unit - $417,000
2 unit - $533,850
3 unit- $645,300
4 unit - $801,950
You can only use your VA loan benefits for your primary residence. So in the case of a multi-unit property, VA would expect you to live in one of the units.
Unless you have Landlord experience (which it sounds like you don't) VA will not allow you to count rental income to qualify for your VA loan. You will need to have sufficient income to qualify for the purchase. Once you have Landlord experience, in the future you will be able to use rental income to qualify.
You are correct. When you refinance your loan away for a VA loan, your VA loan benefits are restored.
