Assuming conservative rents are about $600 X 96 months = 57K lost.
Assuming stagnant property value on a $150K home on a 30 year loan, you pay almost primarily interest in the first 8 years and then have to eat the realtor fees when you sell. $50K in interest + $8K in realtor fees = $58K in losses
A $25K loss doesn't look so bad compared to the alternatives.
