She would like to start investing in flipping homes. She would put up all the financing and we would manage the contractors to fix up the homes and we will split the profit. She has offered to pay all moving expenses and put DH on a salary to help us feel secure. She will also pay for a minimal health insurance policy. (snip) We own a small business here that gives us a small income that we have had for 20 years.
How would the salary she is offering compare to the income you earn now? If she's going to pay him significantly less, in exchange for him getting some of the profit, then you are looking at it the wrong way - she's not offering a job, she's offering an investment opportunity. Don't accept it unless you understand and are comfortable with the risk.
