About to refinance into a rate that will save me approximately $350/month, but extend loan by 4 years.
A) keep making same payments and pay it off about 4 years early that original note
B) pay extra to equal original payoff date, invest the difference
C) go all out, invest the full difference, even though loan would be extended
3.625% on 30y note, 26 years remaining
Refinance to 235k balance, 2.375% on 30y note
If investing is the preference, what type of fund should I be looking at?
