After I consolidated all my student loans in January, my score dropped maybe 10 points once the new tradeline hit my CR. A minimal drop, really, and had no effect on my closing on a house April 30th, nor did it take long for my scores to regain the drop. If you are looking for a mortgage and your scores are borderline, you might want to hold steady for the time being. I don't think having a mortgage will affect your ability to consolidate student loans--maybe if they're private loans. If you consolidate, do it under Direct Loans with the US Department of Education. They are easy to work with. Who are your lenders for your student loans?
