On a conventional loan with 20% down, most will allow you to waive escrow. If they won't, someone else will. If you're doing a 5% FHA loan, you'll have to use an escrow. But then, you probably don't have the discipline (or income) to save consistently, so an escrow is probably a good move.Very few, particularly first time buyers, qualify to not do escrow. I get the philosophy behind your post but what can one earn on an average balance of an escrow account? Then there is the headache of actually paying it. Not worth it to me…
If you're paying $1k+ of HO insurance and $1 - 2k (or more) of taxes, I'd rather earn 4 or 5% on that money than not. Especially if it means I only have to write a few checks during the year to do it. A penny saved, etc...
I've had mortgages with several lenders in my life and every one of them over or underestimated payments almost every year. One forgot to pay my insurance one year. F that!
