Advice on taking over a mortgage in Texas

[Sherrie Price]

If I'm not supposed to post this here or at all please let me know...I don't want to break the rules!

Long story short... I'm recently divorced and my ex and I decided to sell the home  (not in the divorce decree but through mutual agreement) and split the profit. We ended up not being able to sell the home in the time needed. The home mortgage is in his name alone however, both our names are on the land deed. 

My question is... is there a way for me to take over the home? He can't afford to make the payments and the house is currently rented out. He is already behind on payments and I do all the work where the renters are concerned but the rent money goes to him so the mortgage payments can be made. Is there a way for me to take this over completely and make this my first investment property?  

Any advice would be greatly appreciated!
