How do I protect my interests purchasing an investment property with co-owner?

We have decided to purchase an investment property & be co-owners with my boyfriend so we can split the profits upon selling it after 1yr. What legal steps do I need to take to ensure my interests are protected? The mortgage will be under my name. The plan is for him to lease the property for 1 year & make monthly payments that will cover the mortgage. I will continue to rent. We will both contribute equally towards upgrades needed for the house to sell after 1 year. How should he be listed on the title? should the interest be 50/50? What additional legal documentation would be needed incase we decide to split. I realize as the loan will be under my name I will be solely responsible. How can I ensure I can sell the property if I need to if he ceases to rent & I decide not to move in to the property, can I remove his name from the title? How would I need to set this up to begin with to allow for such flexibility. I haven't closed the deal as yet but will be doing so soon.

Many questions there. First find a licensed mortgage consultant to help structure your mortgage. Secondly draw up a contract with some of the facts you listed above, i.e. 50/50 split, you pay the mortgage he pays the rent, etc. and have an attorney look it over. As for vesting you would hold title as tenants in common which your attorney can explain.
