In the Ft. Sill/SW Oklahoma area, military folks sometimes (often over the past couple of years) find they need to move on to their next duty station within 18 to 24 months of purchasing a residence using their VA.
They're still upside down on their mortgage at that point, almost always - so no equity. And we are in a very slow market, so the property could set empty a long time.
These sellers are putting their property on the rental market, often with one of the property management companies in the area. It may take a few months to get rented, but it's often a shorter time period than it takes to sell. That way, somebody is making the mortgage payment.
The soldier, in the above example, may be able to use up the remainder of their VA entitlement to purchase another house. I see this happen every once in awhile.
You might check into selling and buying this way, Paulo. Hope you'll let us know how things work out.
