A Real Stickywicket....

[Jimmy Mozingo]

A good friend of mine is in a failed marriage situation in California. After 12 years of being together, the husband decides he doesn’t want to be married anymore. The house they own has a mortgage in the husbands name. Both names are on the deed. 
here’s the down and dirty on the house:

Mortgage— 434k

ARV—- approximately 650-675k

Mortgage is current 

my friend needs to stay in the house for the sake of her 5 kids

She owns her owns her own nail salon/spa which is mostly a cash business 

Her credit score is 600ish

Because she is not a w2 employee she will have a difficult if not impossible time getting a conventional loan. 
she has asked her ex how he needs to walk away from this mess and he said he wants half the equity. 

How can I help my friend keep her house and pay off her ex without conventional financing? 

Thank you in advance for your suggestions and ideas.
