Hard to say anything without more info.
1. The $50K you’d lose today, what % is that of the price you paid?
2. What % equity do you have in the house?
3. Is your mortgage for 30 yrs? Fixed rate?
4. How many years left in your mortgage?
5. The $200 monthly loss, is that after subtracting PITI only from the rent? Or do you also include an allowance for reserves, maintenance, operating expenses (other than PITI), and vacancies?
