1. Did you discuss this situation with your employer? Do they offer relocation assistance?
2. Have you discussed this with your CPA? Tax-wise having a rental property will have a significant affect on your situation, both while it is a rental and when you decide to sell. This happened to me, we kept it for 18 years and made a lot of money when we sold it...but it was not an easy learning curve.
3. Are you planning to buy when you move? If you have this property as a rental will for debt to income ratio and debt to asset ratio allow you to buy? You could end up renting...which we did.
Have your CPA prepare some scenarios that you can present to your employer. Perhaps when they see the numbers they might find a way to help you out, maybe bump up your salary?
You might be able to narrow that gap a bit by offering your home as a lease-option. Also, with a lease-option you can shift a lot of the burden of maintenance onto the tenant-buyer.
Hope that helps.
