How do I divide my deceased mom's two houses between 3 of us children?

I have been sole caregiver for 9 years. Mom said I should take whatever house I wanted and let the boys share the other one, but they are not equal in value. My brothers think an equal 1/3 is fair. I am inclined to think my mom would have wanted me to be compensated for the care I willingly gave her when the boys were out of state and out of country living their lives. One visited every 3 years and stayed for 3 months to renew his visa and to visit, but would not fix her breakfast or see that she took her pills.. Cooked soups and such, but not helping with caregiving. She had short term memory loss and needed reminders and someone making sure she ate and took meds, etc. Other brother came every 6 months, but again never offered to lighten my load or free up any of my time. just reverted to being the youngest son even though he is an RN working with the elderly. He felt like Iwas keeping him from spending time with her, when in fact I was on the protective side when it came to taking her out for a drive when she wouldn't have enjoyed it. Her likes and dislikes kept changing and her ability to remember and enjoy some things varied...on any given day. My mom put my name on both properties because she trusted me and upon her death they became solely mine. I now need to know what is fair and just as far as how to share the properties. One is worth $410,000 and one is a mobilehome worth $180,000. To be or not to be...generous with them or allow myself extra for the years my life was put on hold for vacations, business meetings, etc.
