They might can hang out a loan longer before it comes due because the balance is so small versus deposit levels at the branch.I usually do not do much business with banks on commercial because simply what they are offering I really consider crap loans for the deal size we do.Had a president of the bank call me the other day selling 3 to 5 year fixed loans with 20 year amort. and full personal unlimited recourse with 30% down.

Do some research on the site(unlimited info on here, almost overwhelming) and I'm sure you will be well on your way.

Lets look at a $100K loan and compare between 15 year and 30 year amortizations.15 year 4% interestPayment $739.69 month, your very first payment is more principal than interestTotal interest paid $33,14330 year 4% interestPayment $477.42 per month, you pay more principal than interest on payment 153 (14y 9 months)Total interest paid $71,868You only get 4 loans on 30 year amortizations, you get unlimited on 15 year loans if you can keep qualifying.
