Not that I'm aware of. There are blanket loans, sometimes used in construction and for commercial property, where one mortgage or loan covers multiple properties. But I doubt you'd be able to do that here. After all, if you're $100,000 upside down on your mortgage, the lender would want some security applying to both of the properties. And I doubt that you've got enough cash to be able to do that.
Plus: Are you really sure that what you're proposing is a good idea? I'm not. Consider: If you were able to do that, suppose you found a new home with a value and a list price of $400,000. You buy it for $400,000, and have your $100,000 in negative equity transferred to the new property. Now you've received nothing for the sale of your old house, and you've spent $500,000 ($400,000 purchase price plus $100,000 in negative equity) on the new house. I doubt a lender would go along with that! And even if a lender did, you'd be $100,000 in the hole, in what, in many parts of the country, is still a declining market. Let's assume prices decline 10% more over the next two years, then are flat for two years. That's not an unreasonable prediction. That means that in four years, your new place would be worth $360,000. Meanwhile, you'd have a mortgage of up to $500,000. You'd only be digging yourself further in the hole. Then, let's say you want to sell after four years. Allowing for a real estate commission and other costs, you'd be adding perhaps another $30,000 in debt. So now we're up to $170,000 upside down on a property worth $360,000.
Check with a good Realtor and get a CMA on your property. Make sure it's worth only $310,000, or so. But you're probably in the general ballpark.
Based on what little you've provided above, I'd strongly recommend that you consider staying where you are. I'm sure you'd like to move to a bigger place. But if you're $100,000 upside down, "liking to move" isn't enough of a reason to do so.
Hope that helps.
