1. Can I still get a mortgage to buy another home, if this loan is still in my name?
The answer is "YES, you can." Mortgage Lenders will see the loan for this house on your credit report, but will consider it a "sale" rather than a liability. As long as you have good credit (which is required for all mortgages), they will not count this loan against you as a debt and it will not affect the amount you can borrow for a new home. You can confirm this fact by calling up any mortgage lender and asking them.
2. I do have equity in my home and I'd like to get some cash out of it?
If you have less than 15% equity, it is unlikely that you would get much (if any) money back after you close if you sell through a real estate agent. Most folks have less equity than what it would cost to sell their property. Which means you would have to come to close with cash to sell your property using a realtor. This small amount of equity is known as "Realtor Equity." It exists if you are successful with selling your home by owner.
It is possible to sell it yourself and get this equity, although you would still have to negotiate with the buyer on the price, make mortgage payments, pay closing costs, and pay for repairs. Statistics show 85% of "For Sale by Owners" are not successful with selling their homes.
