Hi Brad - This is a great question and you are smart by pre-planning prior to making a move. Financing and mortgage rules have drastically changed over the course of the past 18 months. In order to answer the question effectively, a bit more information would be necessary. Program guidelines will vary dependant upon several things. IE: primary vs sencond home; Income; Debt to Income ratios: amount of land; etc., etc. Since the home may be you primary residence, it is important to keep in mind the fact that you will receive the greatest tax benefit from your primary home, therefore it may be a wise move to purchase the home using a mortgage program that requires less down and putting the balance of the cash into the purchase of the land.
I am sorry that I cannot be more specific. If you would like to discuss this in detail, I would be happy to do so. Please either shoot me an email at email@example.com, or feel free to give me a call at 920-858-1203 - I am happy to provide a no cost consultation. Best of luck to you Brad and I hope I have provided you with some things to consider prior to completing your transaction.
