Yes, you need an attorney. There are some factors related to a land installment agreement, or land contract, that you should know. For example, have you paid 20% towards the principal of the contract price during the past three years when adding in any down payment you may have paid? Is the land contract recorded? The recording of the land contract protects you the same as the deed meaning that all are put on notice of you rights to the property. There is so much more - so please, get a real estate attorney!
