Coco,
All the other posters have brought up great opinions for you to analyze. These are opinions on what each persons exit strategy would be if they were in your case.
Stop and think rationally...
You need to take the time and rationalize what you are about to do next. Write down the core problem you need to solve!
Is it that your mom wants to cash out of the property?
Is it that your property is causing you to lose value?
(This is going to take more than a day to solve)
Now that you have a rough problem statement you need to write down a list of potential solutions. The other posters in this forum have brought up some great potential solutions. When you write down possible solutions it does 2 things for you. First, you are forcing yourself to connect your thoughts and rationalize your emotions as to why you think it is a possible solution against your rational. Second, this list allows you to visually the possibilities against each other.
Go Deeper...
Take the top 3 possible solutions and go deeper.
Do some background research by reaching out to the experts in your area. Talk to your local government about what is happening in the community and find out what is happening in your community in the next 5 years. Talk to a few real estate professionals about what your house is worth, what buyers are looking for, how to leverage your current property, ect. When I say real estate professionals i am talking about anyone from an investor, a realtor, a mortgagor, anyone involved in real estate.
It is awesome that you are on BP, now take the next step!!!
