BRRRR 30 year vs 15 refinancing?

[Jonathan Klemm]

This may be a silly question, but why does everyone seem to refer to the 30 year mortgage when talking about refinancing in the BRRRR strategy? Could it not possibly be better to do a 15 year mortgage to reduce the amount you are paying in Interest thus building more equity?

I think people want the lower payment requirement with the ability to make extra payments as they're able to reduce the length of the loan on a 30 yr. If disaster strikes and you have to make major repairs you wont have the option of lowering your payment if you're locked in at 15 yr.
